Guide to Using Harris Parts List Information
The Harris Replaceable Parts List Index portrays a tree structure with the major items being leftmost in the index. The
example below shows the Transmitter as the highest item in the tree structure. If you were to look at the bill of materials
table for the Transmitter you would find the Control Cabinet, the PA Cabinet, and the Output Cabinet. In the Replaceable
Parts List Index the Control Cabinet, PA Cabinet, and Output Cabinet show up one indentation level below the
Transmitter and implies that they are used in the Transmitter. The Controller Board is indented one level below the
Control Cabinet so it will show up in the bill of material for the Control Cabinet. The tree structure of this same index is
shown to the right of the table and shows indentation level versus tree structure level.

The part number of the item is shown to the right of the description as is the page in the manual where the bill for that part
number starts. Inside the actual tables, four main headings are used:
•
•
•
•
•
Table #-#. ITEM NAME - HARRIS PART NUMBER - this line gives the information that corresponds to the
Replaceable Parts List Index entry;
HARRIS P/N column gives the ten digit Harris part number (usually in ascending order);
DESCRIPTION column gives a 25 character or less description of the part number;
REF. SYMBOLS/EXPLANATIONS column 1) gives the reference designators for the item (i.e., C001, R102,
etc.) that corresponds to the number found in the schematics (C001 in a bill of material is equivalent to C1 on the
schematic) or 2) gives added information or further explanation (i.e., “Used for 208V operation only,” or “Used
for HT 10LS only,” etc.).
Inside the individual tables some standard conventions are used:
•
•
•
A # symbol in front of a component such as #C001 under the REF. SYMBOLS/EXPLANATIONS column
means that this item is used on or with C001 and is not the actual part number for C001.
In the ten digit part numbers, if the last three numbers are 000, the item is a part that Harris has purchased and has
not manufactured or modified. If the last three numbers are other than 000, the item is either manufactured by
Harris or is purchased from a vendor and modified for use in the Harris product.
The first three digits of the ten digit part number tell which family the part number belongs to - for example, all
electrolytic (can) capacitors will be in the same family (524 xxxx 000). If an electrolytic (can) capacitor is found
to have a 9xx xxxx xxx part number (a number outside of the normal family of numbers), it has probably been
modified in some manner at the Harris factory and will therefore show up farther down into the individual parts
list (because each table is normally sorted in ascending order). Most Harris made or modified assemblies will
have 9xx xxxx xxx numbers associated with them.
The term “SEE HIGHER LEVEL BILL” in the description column implies that the reference designated part number will
show up in a bill that is higher in the tree structure. This is often the case for components that may be
frequency determinant or voltage determinant and are called out in a higher level bill structure that is more
customer dependent than the bill at a lower level.

Section 1 Introduction
Transmitter Control System
The transmitter uses a distributed architecture control system. This means that each transmitter
sub-system is responsible for its own monitoring and protection and simply reports back to the
Main Controller for display on the GUI (Graphical User Interface) or to a remote interface. The
heart of the system is the 376 Micro Module which is used in all of the transmitter systems for
control, monitoring and protection. The Micro Module is used on each of the following
controllers and sub-systems:
a. Main Controller Board - This board is responsible for transmitter control and
monitoring. However, with the distributed control architecture, it is not directly
responsible for protection of the individual transmitter components. It merely
gathers all status and fault data from the individual sub-systems and reports that
information to the operator. The Main Controller is responsible for system level
control (issues which effect multiple systems) since it is the only part of the control system which can monitor the entire transmitter.
b. RF Monitor Board - Responsible for cabinet VSWR protection and monitoring of
combiner reject loads. Reports directly to the Main Controller.
c. Power Supply Monitor Board - Responsible for control and monitoring of the PA
power supply and distribution of the low voltage. Also responsible for monitoring
the cooling system including temperature and air pressure. Reports directly to the
Main Controller.
d. External I/O Board - Provides all customer interface connections including parallel remote control. Reports directly to the Main Controller.
e. PA Module Controllers (1 in each module) - This is not actually a 376 micro
module but is a micro controller and is responsible for protection and control of
the PA Module. Reports directly to the Main Controller Board via the CAN bus.
1.4.1
Graphical User Interface
The front panel user interface is a 1/4 VGA, LCD touchscreen display. The touchscreen display is
used to monitor the transmitter. Hardware buttons for the primary transmitter functions such as
ON, OFF, RAISE and LOWER are provided on the overlay panel next to the display.
1.4.2
Control System Communications
The control system uses a serial communications system called a CAN bus. CAN stands for
Controller Area Network. The CAN bus is a closed loop serial network operated by the Main
Controller Board. Each circuit board and module connected to the CAN bus is considered a node
and therefore has a specific address. This allows the Main Controller to gather information from
all parts of the transmitter and display it on the GUI. One big advantage of the CAN bus is that it
12/24/07
888-2685-001
WARNING: Disconnect primary power prior to servicing.
1-5
Section 1 Introduction
Ranger Commissioning Manual
requires only 2 wires of the system control ribbon cable, eliminating a large amount of discrete
wiring which would otherwise be required.
For redundancy, the CAN bus is backed up by parallel, hardwired, control lines that allow the
transmitter to stay on the air even if the CAN bus fails. The parallel control lines also provide the
instantaneous OFF and RF MUTE commands necessary for transmitter protection.
1.4.3
In-System Programming or ISP
The use of the CAN bus for communication between the various Micro Modules in the transmitter
also allows for easy updating of the software used in each transmitter sub-system via a serial port
connection to an external computer. This is referred to as In-System Programming or ISP.
The real benefit of In-System Programming is that it allows any or all of the transmitter software
to be updated without removing or replacing any firmware ICs. The Harris ISP program is
provided on the CD-ROM accompanying this manual along with all of the transmitter software as
it shipped from the factory. The Harris ISP program is easy to use and it only takes a few minutes
to load or update software.
NOTE:
Software does not need to be loaded into the transmitter unless new components
are installed or an update is sent from Harris. The transmitter, as shipped from the
factory, is preloaded and ready to run.
1.4.4
Remote Control
The Ranger Series™ transmitter has all of the standard parallel remote control, status and analog
metering connections for use with a third party remote control system. For a complete listing of
the remote control connections, see Table 2-1, Table 2-2 and Table 2-3 at the end of section 2.
1.5
PA Module
The Ranger Series™ PA Module utilizes the same LDMOS amplifier module as used in the
Diamond Series DTV transmitter. Each PA Module will produce up to 400W average power
output. A block diagram of the PA module is shown in Figure 1-3.

Each PA module consists of the following components:
a. PA Module Controller Board - Responsible for all monitoring and protection of
the module. Reports to the transmitter Main Controller via the CAN bus but is
also connected to the parallel control lines in case the CAN bus is not operational.
Also provides for FET switching and distribution of the +32Vdc power to the
driver and PA pallets and sensing of driver and pallet currents.
b. Phase and Gain Board - Provides for module phase and gain adjustments to minimize the PA module combiner reject power for the CZ1000F.
c. One LDMOS Driver Pallet - Provides enough power to drive the 6 way splitter
and the inputs to the power amplifier pallets.
d. Six-way Pallet Splitter and Combiner.
e. Six (6) LDMOS Amplifier Pallets - When combined, they provide up to 400
watts of average power at the output of the module. These pallets are field
replaceable.
f. RF Output Directional Coupler - Samples both Forward and Reflected power for
metering, module ALC and module VSWR protection.

Ranger Commissioning Manual
Section 1 Introduction
Each Ranger Series™ PA Module is a self-contained transmitter (except for the power supply)
with its own internal control, monitoring and protection. The modules only receive basic On/Off,
Mute, Restart, Phase and Gain commands from the transmitter control system. This means that
each module will protect itself without relying on the system controller.
1.6
Power Supplies
A single +32 Vdc switching power supply is used to provide the DC voltage to the PA modules
within each PA cabinet. The power supply can provide power for 1 or 2 PA modules. The control
system in the PA Cabinet is powered by a self contained low voltage power supply with +/-15Vdc
and +7.5Vdc outputs.
1.7
Apex™ Exciter
For information on setup and operation of the Apex Exciter utilizing FLOR technologies refer to
the separate exciter manual, 888-2604-001. The exciter manual is bundled with the transmitter
documentation for shipment.

Interlock Connections
There are 2 types of interlock connections for the Ranger:
•
External Interlock which shuts the transmitter off and requires the user to
give an ON command (local or remote) to turn the transmitter back on. Used
for protection of personnel and equipment. For more information see "2.7.1
External Interlocks" on page 2-8.
•
RF Mute Interlock which only mutes the rf drive and therefore reduces the
transmitter power output to zero. This interlock is meant to be used for a
motorized RF switch or possibly a dummy load thermal interlock.
NOTE:
To operate the transmitter without any interlock connections requires 3 jumpers:

IMPORTANT:
If no patch panel or motorized switch is to be installed in the transmitter RF output line, or if the patch panel does not have status switches, then a jumper must
be placed on the External I/O board from J14-3 (RF_SW_A_STAT) to J14-1
(ground).
NOTE:
Refer to the Ranger External I/O Connections schematic 843-5560-105 for the
following connections: (S1 = Antenna position / S2 = Test Load position)
Connect one side of S1A and S2A on the patch panel to J18-1 and the other side to
J18-2 on the External I/O Board in the transmitter. See External I/O Schematic 8435549-141, sheet 20, for External interlock connections. This is the transmitter external
interlock input and will shut the transmitter off if the U-Link is removed during
operation. A closed contact between J18-1 and J18-2 is required for the transmitter to
operate. Jumpers must also be placed in the other 3 External Interlock positions, J18-3
to J18-4, J18-5 to J18-6 and J18-7 to J18-8 or one jumper from J18-3 to J18-8.
CAUTION:
ALWAYS SHUT THE TRANSMITTER OFF BEFORE REMOVING THE U-LINK
TO PREVENT POSSIBLE DAMAGE TO THE CONTACTS.

normally not used for patch panels), connect a jumper from J18-9 to J18-12.
If the patch panel has status switches then connect S1B and S2B to the RF switch
status inputs on J14 of the External I/O Board in the transmitter. This allows the
GUI to display the position of the patch panel and will cause a transmitter mute if
neither of these connections are pulled low. These connections include:
•
•
•
S1B and S2B commons connect to J14-1 (ground)
S1B (antenna position) connects to J14-3
S2B (test load position) connects to J14-4
NOTE:
If the patch panel does not have status switches then a jumper must be placed
between J14-1 (ground) and J14-3 (RF_SW_A_STAT) on the External I/O board.

Motorized RF Switch Connections (if equipped)
IMPORTANT:
If no patch panel or motorized RF switch is to be installed in the transmitter RF
output line, or if the RF switch does not have status switches, then a jumper must
be placed on the External I/O board from J14-3 (RF_SW_A_STAT) to J14-1
(ground).
NOTE:
Refer to the Ranger External I/O Connections schematic 843-5560-105 for the
following connections: (S1 = Antenna position / S2 = Test Load position)
The RF_SW_SEL_OUT at J15-9 on the External I/O board is connected to the
select input on the switch. This output is a TTL open collector, active low, momentary
signal meant to cause a switch to the opposite position. The RF switch should then latch
in that position until pulsed again.
One side of S1A and S2A (interlock switches on the rf switch) is connected to J18-9
and the other side to J18-10 on the External I/O Board in the transmitter. See
diagram 843-5560-105 and/or 843-5549-141 sheet 20, for RF Mute interlock
connections. This is one of the transmitter rf mute interlock inputs and will mute the
transmitter while the switch changes position. Another jumper must be connected
between J18-11 & J18-12 to operate the transmitter.
If the patch panel has status switches then S1B and S2B are connected to the RF
switch status inputs on J14 of the External I/O Board in the transmitter. This
allows the GUI to display the position of the patch panel and will cause a transmitter
mute if neither of these connections are pulled low. These connections include:
•
•
•
S1B and S2B commons connect to J14-1 (ground)
S1B (antenna position) connects to J14-3
S2B (test load position) connects to J14-4
NOTE:
If the patch panel does not have status switches then a jumper must be placed
between J14-1 (ground) and J14-3 (RF_SW_A_STAT) on the External I/O board.
The transmitter will be muted without this connection.
Confirm that the jumpers in the External I/O board for all unused External

Figure 2-9 Exciter Inputs and Outputs
ASI #1 and or ASI #2 are connected to the exciter for the low and high priority ASI
transport streams. For best common mode rejection, this cable shield should be
grounded only at the source end.
The input impedance for each connector is 75 ohms. Belden 8281 or similar highquality video cable can be used to deliver this signal to the exciter over a distance of up
to 1000 feet.
ASI OUT is a sample output of the active transport stream. It should not have a cable
connected to it unless specified locally.
ANT (GPS antenna input) connector should not have a cable attached since the GPS
receiver is an option and not present in most Mobile exciters.
10MHZ REF IN (BNC) is optional and normally not used in a Mobile system.
1PPS (1 pulse per second input from the GPS receiver) should have a cable connected
to it that comes from the GPS receiver.
HPF RF SAMPLE IN (SMA) has a cable connected to it that comes from the output of
high power mask filter. It is used by RTAC™ (Real Time Adaptive Correction) to
correct for the linear distortions of the high power filter. Normal input signal range is 30 dBm to 0 dBm. The input impedance is 50 ohms.

PA SAMPLE IN (SMA) should have a cable connected to it that comes from the output
of the transmitter power amplifier, taken before the HPF and after the PA combiner for
transmitters with multiple PAs. It is used by RTAC™ to correct for the nonlinear
distortion caused by the power amplifier. Normal input signal range is -30 dBm to 0
dBm. The input impedance is 50 ohms.
IPA SAMPLE IN (SMA), is not used. There should be no cable connected to this
exciter input.
RF OUT (SMA) should be have a cable connected to it. This is the on-channel RF
signal output from the exciter. The output level is adjustable up to 250 mW average but
is intially adjusted to produce an 80 ALC value on the transmitter GUI display.
EXC/CTRL UHF (25 Pin D) should not have a cable connected to it.
CAN (controller area network) should have a cable connected to it. The connector is a
provision for the exciter to communicate with the transmitter GUI (graphical user
interface) system controller.
LAN 10Base-T should have a cable connected to it. The connector is a provision for
connecting the exciter to a local area network.
RS232 (on front and rear panels of exciter) is a 9 Pin D interface connector and they
should not have cables attached to them. They are used to communicate with various
computer applications. The front and rear panel connections can be programmed and
used independently of each other.
2.11.1.2 AC Power
AC Power is applied through a standard power cord to the connector at the right side of
the rear panel as shown in Figure 2-9. The AC inlet connector also contains the power
switch.
The power supply will automatically select the AC input voltage in two ranges. The two
ranges are 85 to 132 VAC or 170 to 264 VAC
2.11.1.3 Verify Installation of the GPS 1PPS Signal
The GPS (global positioning system) 1PPS (1 pulse per second) signal has a rise time in
the order of a few nanoseconds. It is delivered by a 50 ohm transmission line to the
exciter. Improper termination can cause ringing on the pulse, which, if severe enough
can cause timing errors in the system. The 1PPS signal must be properly distributed and
terminated to avoid the ringing problem.

All control inputs use opto-isolators for surge protection. The opto-isolators are
powered by an internal +5Vdc from an isolation protection circuit, U54. All transmitter
control functions (except Remote RF Mute) are momentary ground switching and
require the remote control equipment to sink at least 15mA to activate the function. The

Under certain critical fault conditions, the PA module will try to shut off (Strike) and
then re-initialize to try and clear the fault condition. If the fault is still present after the
module turns back on it will shut off (Strike) again. If the fault is still present after a 3rd
strike or returns within several seconds after the 3rd strike, the fault is latched and the

PA Data
The PA Data screen in Figure 3-9 is accessed from the PA Meters screen in Figure 3-8.
It contains vital information about the operation of the PA module. The readings are
ADC or DAC counts in either 10 bit (0 - 1023) or 12 bit (0 - 4095). For detailed theory
on the PA Module refer to Section 4, Theory of Operation.
a. Phase - This is an analog voltage from the Backplane Interface board which is
used to adjust the insertion phase of the module. In the CZ1000F this is used to
adjust the phase of PA Module 2 to match that of PA Module 1 (and to optimize
the PA Module combiner). The module controller converts the analog voltage
from the Backplane Interface board to a digital 10 bit word from 1 - 1023 with the
ideal being 512 or centered in the range. PA Module 1 receives a fixed voltage
which places it approximately in the center of the range (it is not critical), while
module 2 receives a variable voltage via R7 on the Backplane Interface to allow
for module phasing. This input controls the I and Q Vector outputs to the Phase
and Gain board in the module.
Figure 3-9 PA Data Screen
b. I and Q Vectors -These are 12 bit DAC outputs from the module controller to the
Phase and Gain board in the module with a range of 0 - 4095. The phase voltage
from the Backplane Interface board adjusts these readings in opposite directions
to set the insertion phase through the module but they are also used to adjust the
module gain as part of the module AGC. These readings are considered OK as
long as they are not at the limit of the range. If either of these numbers are 0 or
4095, the PA Faults screen will register an AGC Unlock fault.
c. Phase Preset - This is a fixed setting inside the module and should read approximately 512.

d. DAC Counts - These are 10 bit (0-1023) ADC samples of the detected RF input
and Forward and Reflected power output.
•
IN - Is a sample of the detected RF drive input to the module. Nominal input
for 400W output is 15mW. This number is usually in the 800 range for full
rated output. The input overdrive fault is detected from this reading and is
triggered when the DAC reading is approximately 1.9dB above nominal or
•
Out - This is a sample of the detected forward power sample from the
directional coupler on the module output. This is used for metering and as
the sample for the module AGC. This number is forced by the AGC to track
the IN reading, thereby keeping the module gain at 46dB.
•
Reflected - This is the detected sample from the reflected coupler on the
module output. It is used for metering of reflected power or VSWR. Can be
used as a relative reading to detected changes in the module output.
e. Module Settings - These are status readings from the module to the transmitter
controller. The FREQUENCY and the BAND are set via the Channel number
entered into the System Setup screen shown in Figure 3-22. These are simply
read backs to verify that the module is setup properly. If not set properly, module
calibration could be affected. All Ranger modules should read HD (High power

PA Setup (Gain Balance)
This screen is accessed by pressing the PA Setup button in Figure 3-10. Its sole purpose
is to balance the gain of the 2 PA modules in the CZ1000F transmitter. The goal is to
match the 2 module gain readings. Adjustment is only required if the module current
readings in Figure 3-11 are more than 1 amp apart. This procedure will have to be done
if a module is changed. The adjustment procedure is simple.
NOTE:
This adjustment should only be done at full power and after the module temperatures have had time to stabilize. PA Module phasing should always be optimized
after finishing this procedure.
STEP 1
Press the RESET button. This allows the adjustment to always start from
a common point.
STEP 2
Use the Left and/or Right arrow buttons until the numbers match. There
will be some bounce in the readings, but they should be as close as
possible and no more than 1 amp apart.

NOTE:
This adjustment is not to be used to decrease the PA module combiner reject
power. In some cases this adjustment may actually increase the PA module combiner reject power by a few watts.
It may be necessary to adjust the PA module phasing via the pot on the Module

b. Output Power Meters - This panel gives the Forward and reflected power outputs
both before and after the built-in mask filter.
c. Output Control - This area of the screen can be used to control an external motorized RF switch so that the transmitter can be switched from Antenna to the Test
Load, provided the System Configuration screen in Figure 3-23 on page 3-28 is
set for “Motor”. For systems with a manual patch panel the System Configuration
screen should be set to “Manual”. It also reads out the position of an RF switch or
a 3-port patch panel, based on micro-switches located on the switch or panel.
Lastly, it shows the condition of the Test Load interlock. The test load interlock
will not affect transmitter operation if the switch is in the antenna position.
NOTE:
If the load interlock (also called the RF Mute Interlock) is open and the transmitter is switched to the “Test Load” position, the transmitter output will be muted.
If a test load interlock is not used the appropriate connection on the External I/O
board must be jumpered. For more information see "2.7 Interlock Connections"
on page 2-7.

Output Service
This screen is accessed from the Output screen in Figure 3-12. It is used for 2 purposes:
a. To monitor the PA Module Circulator reject power. Provides a bargraph and a
DAC count of 0 - 1023 (0 meaning no reflected power and 1023 being maximum). This allows for a relative reading which can be monitored for changes
which could mean increased system VSWR or a bad circulator. There is no
adjustment for this reading.
b. To monitor Combiner Reject Load Power in the CZ1000F. Provides a bargraph
and a DAC count of 0 - 1023 (0 meaning no reflected power and 1023 being maximum). It is used to adjust the phase relationship of PA Module #2 to minimize
the power to the module combiner reject load. The combiner reject load is actually a 40dB 1kW attenuator whose output is sent to the RF Monitor board where
it is detected and then A/D converted for the reading shown below the “PA 1&2”
bargraph. It is a relative reading which will simply be minimized with the phasing
adjustment R7 on the Backplane Interface board. See "3.7.2 Module Phasing Procedure".

NOTE:
The GAIN button can be toggled between LOW and HIGH, with high only being
used to increase the detector resolution for finer adjustment of the module phasing. Proper phasing can usually be obtained using only the LOW setting and
monitoring the DAC reading.

Module Phasing Procedure
NOTE:
This procedure is for the CZ1000F only.
The goal is to minimize the PA module combiner reject load power reading in Figure 313, by adjusting the phase of module #2. The phase of PA module #1 is fixed. The “PA
1&2” reading should be less than 0030 with the GAIN button at the bottom of the
screen set to LOW. If the GAIN button is pressed it will toggle to high, increasing the
detector gain and allowing for finer resolution when adjusting module phasing. The
reading should be less than 0100 with the GAIN set to HIGH.
STEP 1
Check the PA module gain balance on the PA Setup screen, shown in
Figure 3-11 on page 3-14. These current readings should be less than 1
amp apart. If not, refer to "3.6.4.1 PA Setup (Gain Balance)" and adjust
the module gains before proceeding with the module phasing.
STEP 2
Using a digital voltmeter, monitor the test point on the Backplane
Interface board shown in Figure 3-14.
Phasing Adjust R7
Module Phasing
Test point (pad)
Figure 3-14 Test Point for Module Phasing
STEP 3
Adjust R7 (the only potentiometer) on the Backplane Interface board for
minimum voltage reading on the voltmeter. This should minimize the
reading on the Output Service screen in Figure 3-13. The location of the
Backplane Interface board is shown in Figure 2-1 on page 2-2 under the
letter N.
NOTE:
The reject power should be less than 12W when finished.

Output Setup
This screen is accessed by pressing the Output Setup button on the Output Service
screen in Figure 3-13. It is used to calibrate the filter input power and Total cabinet
Forward and Reflected power (after the filter).
It also calculates the VWSR protection thresholds of Foldback power and Fault
threshold and displays them at the bottom of the screen. These values are based on the
“Nominal Power Output” value entered into the System Setup screen in Figure 3-22 on
page 3-27.
•
The foldback level is calculated using a VSWR = 1.4:1. Therefore the actual
foldback power can be calculated as:
Foldback Power = Nominal Power Output x 0.0278
•
The fault threshold is calculated using a VSWR = 1.9:1. Therefore the actual
fault threshold can be calculated as:
VSWR Fault Threshold = Nominal Power Output x 0.0963

Forward and Reflected Power Calibrations
The following procedure is used to calibrate the forward and reflected power readings
via the Output Setup screen. The forward must be calibrated first, then the reflected can
be calibrated. The procedure requires a digital power meter and a 10dB pad. Since
calibration is relatively easy and quick, it is recommended that both forward and
reflected always be calibrated together.
Forward Power
STEP 1
Connect the digital power meter to the forward power (incident) port on
the directional coupler either before or after the filter. For the location of
these ports see Figure 2-1 on page 2-2, designated B and R. The cables
numbers connected to these ports are #40 for the Total output and #42 at
the filter input.
STEP 2
Measure the power at the forward coupler. The coupler comes with a
table of precision coupling values for the various UHF channels which
should be used as the offset for the digital power meter. Make sure the
coupler serial number matches the coupling table. The coupling values
are also written on stickers which are attached to the couplers at the
factory.
STEP 3
Press the CHANGE button to select the coupler being calibrated (before
or after the filter) and then use the +/- buttons to make the displayed
power match the measured value on the digital power meter.
STEP 4
Press SAVE to store the setting or CANCEL to discard the changes.
Reflected Power
3-20
STEP 5
Press the CHANGE button for the desired reflected coupler (before or
after the filter). This temporarily disables the reflected power fault.
STEP 6
Note the forward power and remove the power meter from the forward
coupler. Connect the 10dB pad to the forward power coupler.
STEP 7
Remove the cable from the reflected coupler to be calibrated and connect
it to the 10dB pad. The cables are labeled #50 for the Filter input and
#39 for the Total reflected.
STEP 8
Use the +/- buttons to set the reflected reading on the GUI to 10% of the
forward reading noted earlier.
STEP 9
Press SAVE to store the setting or CANCEL to discard the changes.

System VSWR into station load
System VSWR into transmission line and antenna.
CAUTION:
PRIOR TO MEASURING THE VSWR OF THE TRANSMISSION LINE AND ANTENNA
MEASURE THE AMOUNT OF RF PRESENT ON THE TRANSMISSION LINE. IN
AREAS OF HIGH RF RADIATION THERE MAY BE ENOUGH RF PRESENT ON THE
TRANSMISSION LINE TO DAMAGE THE INPUT OF THE NETWORK ANALYZER. IN
THESE INSTANCES IT MAY BE NECESSARY TO USE AN AMPLIFIER AT THE
OUTPUT OF THE NETWORK ANALYZER IN ORDER TO GET ACCURATE
MEASUREMENTS.

PA Module Removal
The PA module(s) simply push in or pull out of the transmitter. There are no latches or
screws. There is a module off switch located behind the front cover at the top and
bottom of the module so that when the module is grasped to be pulled out, the touch
switch shuts it off first.

CZ1000F PA Module Air Block
For the CZ1000F, a special Air Block (a long, thin Lexan shield shown in Figure 5-1)
has been provided in case one of the modules is to be removed for an extended period of
time. The Air Block simulates the back pressure of a module. This keeps the airflow
through the rest of the transmitter at normal levels even with the module removed. The
Air Block will only fit in Slot #2 (the right-hand slot). Therefore, if a module is to be
removed for a period of more than a few hours, the Air Block should be installed in slot
2 and the remaining module must be placed in slot 1 (if not already there).

To install the Air Block, place the right side into the slot as shown in Figure 5-2. To
finish, squeeze near the back until it starts into the slot on the left. Now using either
your hands or a screwdriver, work it into the slot from back to front. It could also be
installed starting at the front and working your way to the back, whichever works best
for you. When finished, both sides of the Air Block should be captive under the shelf.
NOTE:
If you use a tool to aid installation, be very careful not to bend the aluminum
guide to the left of the slot.
Note: The slot is installed around
the aluminum bracket.

per clamps can be used to finish removal of the board with less pressure
required.
STEP 7
Remove the thermal pad from the heat sink and discard. These pads
should not be reused.
STEP 8
Wipe off any thermal grease or other residue from the heat sink using the
cotton cloth and alcohol. Make sure the surface is completely clean in
preparation for the installation of the new pallet.
STEP 9
Install the new thermal pad. The pad is oriented so the brown wire is
passed through the hole as the pad is installed on top of the heat sink. It
does not matter which side of the thermal pad is up and which side is
down as there is no performance difference.
STEP 10
Position the new PA pallet in place with the brown wire directed through
the corresponding hole in the pallet.
STEP 11
After the pallet is placed, make sure the DC power wire passing
underneath the pallet is entirely inside of the designated channel in the
heat sink and is not between the pallet and the heat sink.
STEP 12
Install the seven mounting screws and torque each to 15 inch pounds.
STEP 13
Solder the brown DC power wire onto the newly installed pallet using
the soldering iron and Sn63Pb37 solder.
STEP 14
Use an Ohmmeter to check the resistance from the brown power wire
pad to ground. It should be 1K ohm or greater. If the meter shows a short
circuit or low Ohm reading between these two points, remove the pallet,
and check the wire position underneath the pallet. Fix the position of the
wire and re-mount the pallet.
STEP 15
Solder the input and output ribbon wires to the pallet, make sure the
ribbon wire is not broken, damaged, or touching ground at any point.
STEP 16
Clean all three solder connections with a piece of cotton cloth and
alcohol.
STEP 17
Replace the lid on the module and reinstall all the screws.
Install the module back into the transmitter and push the ON button, check the value of
the DC current consumed by the new pallet. It should be the same as for the rest of the
pallets +/- 10%.

Power Supply Module Replacement
Removal and replacement of the power supply module is a simple matter of shutting off
the breaker on the front of the module, removing the 2 black screws in the front panel
and pulling the module out.
Before replacing the module with a new one be sure to check the AC voltage strapping
on the front side of the supply (inside the aluminum chassis). The power supply
modules can be strapped for 240 or 480 Vac but all Ranger supplies should be strapped
for 240 Vac operation. Proper strapping for 240Vac is shown in Figure 5-4, along with a
picture of the inside of the actual supply chassis. This information (and 480Vac
strapping) is also shown on the Power Supply Wiring Diagram, 843-5494-353 in the

Circulator Removal/Replacement
The circulators are mounted on an adjustable plate behind the PA modules. It is very
important that when they are replaced that they are mounted correctly or the module
may not seat properly in the circulator. If mounted too far forward, the circulator could
actually hold the module out so that it does not seat properly in the lower module
connector which carries PS, signal and control causing the module not to operate or
become intermittent.
STEP 1
Shut the transmitter off along with the breaker on the power supply.
STEP 2
Pull the PA modules out a few inches to disengage them from the rear
connectors.
STEP 3
Mark the adjustable plate shown in Figure 5-5 for front to back position
(F) on the top as shown and on the bottom. This will make re-assembly
much easier and increase confidence that it is back in the correct
position.
STEP 4
Remove the RF output cables (D) and the reject cables from the
circulators. If necessary, mark them for proper installation later.
STEP 5
Remove the adjustable plate screws (C) and pull circulator assembly
straight back. This should provide access to the screws on the side of
either circulator. The heatsink screws pass all the way through the
heatsink and should only be removed if better access to the circulator
screws is required.

STEP 7
Clean the old thermal compound off of the heatsink with cotton cloth
and alcohol. Put a thin layer of thermal compound on the new circulator
and mount it to the heatsink.
STEP 8
Push the modules back into place. Have someone hold the modules
firmly in place or tape them to the cabinet for the next step.
STEP 9
Re-install the adjustable plate with the circulators mounted on it. With
the modules held in place, seat the circulators into the module. The
marks you made earlier should be very close to lining up. They should
not be any further away from the module than before. The most
important thing is that you are not holding the module away from the
lower connector but are making good RF contact to the circulator.
STEP 10
Tighten the screws (C) in the adjustable plate and then re-connect the RF
output and reject cables to the circulators. Make sure you connect the
cables to the same circulator as before.
NOTE:
Swapping the output cables will cause all of the power to end up in the combiner
reject load, while swapping the reject cables will cause the attenuator readings to
be reversed on the GUI and therefore protect the wrong attenuator.
It should not be necessary but you may want to check module phasing and adjust if
necessary for the CZ1000F, see "3.7.2 Module Phasing Procedure" on page 3-18.

Introduction
This section provides step by step procedures for updating the software loaded onto
each of the controllers in the Ranger transmitter via the In-System Programming feature
or ISP. This allows for software updates without having to change firmware ICs. The
ISP program and the software files for each of the controllers is supplied on the CDROM which came with the transmitter, along with an acrobat version of the technical
manual. The ISP program requires an external Windows PC with an available RS-232
serial port which can be connected to the Main Controller board. This single connection
(via ISP bridging) will allow updating of all controllers, including:
•
•
•
•
Main Controller Bd
PS Monitor Bd
RF Monitor Bd
External I/O Bd
NOTE:
The PA Modules require a different serial connection point and therefore have a
separate ISP procedure than the 4 controllers mentioned above.

Installing the ISP Program
The In-System Programming (ISP) application, HarrisISP.exe, is a Windows based
software program. The main requirements are a Windows based PC and an open COM
port.
To install the HarrisISP.exe program simply double click the Setup.exe program located
on the CD-ROM in the directory D:\Firmware\Isp\ as shown in Figure 6-1 or use the
RUN command in the START menu.
Double Click to Launch Install program
Figure 6-1 CD-ROM ISP Directory
Simply follow the on screen instructions and do not change the paths where
the program wants to be installed. When finished you should have the Harris
ISP icon on your desktop, like the one to the right.

ISP Procedures
The ISP procedure is basically the same for all of the control boards (Main Controller,
RF monitor, PS monitor and External I/O) but is slightly different for the PA Module
controller. The main differences are the serial connection point and the baud rate. This
means there are 2 ISP procedures:

Section 6 ISP (In-System Programming)
When firmware in the transmitter is updated, all firmware revisions (for the controllers
and the modules) should be checked and brought up to the revision levels on the CDROM if not already the same. The .s19 file names for the controllers and the modules
have the revision number as part of the name.
For example: RANGER_CTRL_APP_0013.s19 is revision 1.3 Main Controller code.
NOTE:
There is a separate ISP procedure used to update the Apex exciter. See the Apex
exciter manual for details on updating Apex exciter software.
6.3.1
Control System ISP Procedure
The example given here is for updating the Main Controller board since the steps are
the same for the other control boards except for the update file. This means the
procedure is to be repeated for updating each of the following control boards:
•
