Test Set Description
Test Set Description
The HP 8517B test set configured with an HP 8510B/C network analyzer
and an HP 8360 series source, creates a system capable of making
S-parameter measurements from 45 MHz to 50 GHz. The system is
particularly suited for making two-port device measurements. You can
measure all four S-parameters without physically reversing the DUT (device
under test).
The system is also designed for making measurements on non-reciprocal
devices or components like transistors, amplifiers or isolators where S12
measurements are required.
Two directional couplers are used for signal separation. The configuration is
illustrated in the following figures:
•

Figure 1-2, “Option 004, HP 8517B Test Set Block Diagram"
Figure 1-3, “Option 007, HP 8517B Test Set Block Diagram"
For active-device measurements, two bias tees apply external DC bias to
both test port center conductors.

Verifying Test Set Operation
The test set is designed to operate with an HP 8510C network analyzer. You
can verify its operation by:
Table 1-2
Test Set Operation Verification
Checking System Operation
Perform a system calibration as described in the HP 8510C Operating and
Programming Manual. A successful calibration indicates that the system, and
therefore the test set, are operating properly.
Checking Specifications
Specifications for the test set, and the system, can be determined by running
the specification and performance verification software described in the HP
8510C On-Site Service Manual, Chapter 8, “Specification and Performance
Verification”. Additional mechanical specifications and supplemental
characteristics are in Chapter 4, “Specifications” of this manual.
Troubleshooting the Test Set
To troubleshoot the test set, refer to the HP 8510C On-Site Service Manual.

Maintaining Measurement Accuracy
Maintaining Measurement Accuracy
Precision measurements rely on a precision calibration of the network
analyzer. As a general rule, the shorter the time lapse between a calibration
and a device measurement, the more precise the measurement results will be
(within the limitations of your system).
Hewlett-Packard recommends calibrating your system every few hours, or at
least re-verifying your system’s calibration this frequently. Doing so helps
retain measurement precision.
The frequency of calibrations is determined by both the location of the
system and the ambient temperature stability in its operating area.

Controlling Multiple Test Sets
HP 851X Series, Option 001 test sets allow an HP 8510C to alternately
control up to four test sets connected to it. For example:
•
While a measurement is underway on test set number 1 (equipped with
Option 001), a test device can be connected to test set number 2 (which
does not need Option 001).
•
When the measurement on test set number 1 is complete, the HP 8510C
can then control test set number 2.
In a standard test set, the 20 MHz IF and control signals are applied directly
to J11 TEST SET INTERCONNECT, which is attached to the HP 8510C.
Option 001 adds a set of IF switches, control switches, and the J10 TEST
SET INTERCONNECT attachment. This configuration allows the selection
of the 20 MHz test set IF signal.
As shown in Figure 3-3 on page 3-4, test set number 1 can:
•
•
apply its IF signal to the HP 8510C, or it can
switch to pass the IF signal from test set number 2, through J10 TEST
SET INTERCONNECT, and into the HP 8510C.

Multiple Test-Set Connections
For dual test-set configurations, set each rear panel address switch on each
test set to the address shown in Figure 3-3. Refer to Figure 3-4 on page 3-7
for the configuration of two or more test sets.
•
Use the supplied test set interconnect cable to attach test set number 1,
J11 to the network analyzer.
•
Use the supplied test set interconnect cable to attach test set number 2,
J11 to test set number 1, J10.
You may connect up to four test sets in a series if the total length of all test
set interconnect cables does not exceed 13 meters (about 40 feet). The last
test set connected in the chain does not require Option 001.
If the RF coaxial switch is not incorporated into the system, the RF input to
the test set must be manually switched to the active test set.
Initialization at
Power-Up
At power-up, configure the IF switches so that only one system test set is
active. To verify which test set is active, use the following steps:
1. Verify that all system test set LEDs are lit.
2. View the network analyzer’s test set address by pressing the
INSTRUMENT STATE, [LOCAL] key, then press {TEST SET}. The HP-IB
address of the test set is displayed on the screen.
The address displayed must match the address of the test set selected. If
not, enter the correct address using the network analyzer’s key pad.
3. If an unselected test set’s LEDs are lit, deactivate it. Do this by entering
its address, pressing [x1], then entering the address of the test set desired,
followed by [x1].
Selecting a Test Set
To select another test set, follow the procedure in Table 3-4 on page 3-6 of
this chapter.
HP 8517B S-Parameter Test Set Manual 3-5
Table 3-4
Test Set IF Switching
Selecting a Test Set When Multiple Units are Configured
A test set is selected via the built-in capability of the analyzer to generate an addressed
command to each test set. Each time you change the {HP-IB ADDRESS} {TEST SET}
function (refer to LOCAL [MENU] in the HP 8510C Operation and Service Manual), the
network analyzer does the following:
• switches the IF signal of the previously addressed test set to external
• switches the IF signal of the newly addressed test set to internal
• sets the test set’s front panel ACTIVE LED to indicate test-set status
• applies the active test set’s IF signals directly to J11 TEST SET INTERCONNECT
• passes the inactive test set’s IF signals at J10 through to J11 and on to the next
test set or to the network analyzer
Test Set Addressing
You can change the test set address via program control, or via the network analyzer front
panel keys. You must also change the mechanical switches on the test-set’s rear panel.
Here’s how:
1. Change the test set address via the network analyzer keys;
a. On the analyzer’s front panel, press the INSTRUMENT STATE [LOCAL] key, then
press {TEST SET}. The test set’s address appears on the display.
b. Using the key pad, enter the desired address for the test set, then press [x1]. The new
HP-IB address appears on the display.
2. Change the test set address via the HP-IB command:
From the controller, enter the HP-IB ADDRESS; command, followed by the
address value. Refer to the command reference for programming details.
3. Reset the mechanical switches on the test-set’s rear panel. Set the switches to match the
new HP-IB address displayed on the network analyzer screen.
RF Switch Driver Control
When the {HP-IB ADDRESS} {TEST SET} function is changed, the network analyzer
generates a code sequence. The code sequence is automatically issued across the
HP 8510C system bus to the device at the ADDRESS of RF SWITCH .
In the recommended configuration, the device is an HP 11713A attenuator/switch driver. The
switch/driver in turn controls one or more coaxial switches. These switches, (shown in a
Figure 3-3, and Figure 3-4) are used to choose which test set receives the RF output from the
network analyzer source.
The exact command issued depends upon the new value of the {HP-IB ADDRESS}
{TEST SET} value, also shown in shown in a Figure 3-3 and Figure 3-4.

Measurement Calibration
After selecting the active test set, complete the system calibration procedure
as usual. When you select a different test set, make sure that you recall the
cal set that applies to that test set.
NOTE
Since the cal-set limited instrument state does not include the number of the
active test set, a cal set which does not apply to the current test set can be
turned on without displaying the HP 8510C caution messages. However, this
causes errors in the data displayed because incorrect error coefficients are
applied to the measured data.
For convenience, store a hardware-state file and an instrument-state file for
each combination of test set to cal set. You may also store your hardware
state file on a tape or disk for future use.
To change the configuration, recall the appropriate hardware state file. The
hardware state file:
•
•
•
•
sets the address of test set
issues the RF switch command, then
recalls the appropriate instrument state file which
recalls the cal set
HP 8517B S-Parameter Test Set Manual 3-8
Measuring High-Power Devices with Option 004
The HP 8517B, Option 004 test set enables devices with output power up to
30 dBm (1 watt) to be measured at Port 2, without adding external
attenuators. Reverse dynamic range (S12) degrades by approximately 3 dB.
When measuring devices having greater than +17 dBm output power, you
must use the Port 2 step attenuator to decrease the power to ≤+17 dBm.
The step attenuator has to be set during calibration for the value needed
during device measurements. However, this setting may cause inadequate
power level during calibration. Refer to “Changing Signal Path States After
System Calibration” on page 3-10 for additional information.
HP 8517B S-Parameter Test Set Manual 3-9
Changing Signal Path States After System
Calibration
Changing an internal attenuator or any external equipment after completing
the calibration means the measurement results cannot be specified. You must
use your own estimation of the potential error contribution due to the
change.
For example, when the port attenuation is changed with correction ON, the
message CAUTION: CORRECTION MAY BE INVALID displays. You must judge
whether the error is tolerable in the particular application and how to
compensate for the change.
The application question is: “Does increasing the signal level during
calibration improve the calibration enough to risk a possible increase in error
contributions when you change the setup?”
The only reason for changing an internal attenuator or external equipment
between calibrations and measurements is to maximize the signal level
under both conditions, thus minimizing uncertainty due to noise.
Many factors enter into a setup-change decision, for example:
•
•
is it more accurate to calibrate at a low signal level without changing the
setup, or
is it more accurate to change the setup to optimize levels for both the
calibration and measurement
Changing attenuators at Port 1 or Port 2 does not change the test set
mismatch, directivity, or isolation characteristics severely. It does change the
frequency response magnitude and phase, however. The difference between
frequency response calibration and measurement can be normalized by using
HP 8510C trace memories.
Changing the Test Port
Attenuators
If only the attenuators at Port 1 or Port 2 are changed, use the following
procedure to minimize errors:
1. Connect a short, or a thru, and set Port 1 and Port 2 attenuators for the
best IF signal levels during calibration.
2. Perform the appropriate measurement calibration.
3. Connect the correct calibration standard, set Port 1 and Port 2
attenuators to the value required for operating the test device.
HP 8517B S-Parameter Test Set Manual 3-10
If you view the response of a short circuit, notice that:
•
•
Changing Port 1 attenuator has negligible effect on S11 marker reading
Changing Port 2 attenuator has negligible effect on S22 marker reading
This is due to the way the attenuators are paired. Both the reference and the
test signal are changed by approximately equal amounts.
When viewing S21 or S12, however, changing Port 1 or Port 2 attenuators
offsets the marker reading by the difference value between Port 1 attenuator
and Port 2 attenuator.
Storing Trace
Memories
To compensate for the main frequency response effects due to changing
the attenuators, use the HP 8510C trace memories and trace mathematics
function, as explained below:
1. Connect the thru used for calibration and set the port attenuators to the
value used for device measurement.
2. Recheck the user parameter levels, then press PARAMETER [S21].
3. Press MENUS [DISPLAY], then {DATA AND MEMORIES}.
Press DISPLAY: {DATA-->MEMORY n} to store the S21 trace in default trace
memory 1. This trace represents the frequency response difference
between the S21 signal path calibration and the measurement.
4. Press PARAMETER [S12], then press the following DISPLAY: menu keys:
{SELECT DEFAULTS}
{DEFAULT to MEMORY: 2}
{DATA-->MEMORY 2}
The S12 trace is now stored in trace memory 2. This trace is the
frequency response difference of the S12 signal path between calibration
and measurement.
Viewing Normalized
Parameters
Use the traces stored in memory 1 and memory 2 to normalize the corrected
data to the new levels after the attenuation is changed. The next example
uses normalization for S21 or S12, only. To view the corrected parameters:
1. Press MENUS [DISPLAY], then {DATA AND MEMORIES}
2. Press PARAMETER [S11] and view the S11 measurement.
3. Press PARAMETER [S22] and view the S22 measurement.
4. Press PARAMETER [S21], then the following DISPLAY: menu keys:
{SELECT DEFAULTS}
{DEFAULT to MEMORY: 1}
{MATH ( / ) }
HP 8517B S-Parameter Test Set Manual 3-11
5. View the S21 measurement. If the thru is connected, the transmission
coefficient should be 1 ∠0° .
6. Press PARAMETER [S12], then press the following DISPLAY: menu keys:
{SELECT DEFAULTS}
{DEFAULT to MEMORY: 2}
7. Press PARAMETER [S12] to view the S12 measurement. If the thru is
connected, the transmission coefficient should be 1 ∠0° .
Normalization is turned OFF for S11 and S22 measurements. Then the
appropriate memory is selected and normalization is turned on to view S21
and S12.
Since these are accurate, repeatable attenuators, this sequence may be
effective in your application. If other parts of the test must be changed,
especially components connected to the test ports, this procedure may
require additional steps to adequately compensate for the changes.
HP 8517B S-Parameter Test Set Manual 3-12
Making Operational Checks
To check the operation of multiple test-set configurations, do the following:
1. Connect a device with a known response to test set number 1. Press the
following HP 8510C front-panel keys:
INSTRUMENT STATE [LOCAL]
AUXILIARY MENUS [SYSTEM]
{HP-IB ADDRESSES}
{TEST SET}
2. When the message TEST SET HP-IB ADDRESS appears, enter [20], the
address of test set number 1, then press [x1]. The measurement trace from
test-set number 1 should display.
3. Store the trace in memory by pressing the following keys:
MENU [DISPLAY]
{DATA AND MEMORIES}
{DATA --> MEMORY n}
DISPLAY: {DATA and MEMORY]
4. Next, enter the HP-IB address of test set number 2, followed by [x1], then
re-enter the address of test set number 1 followed by [x1].
5. Repeat the above procedure for each of the other test sets in the system.
Observe any difference in the response between the stored trace and the
results trace by switching back and forth between the test sets.
Any differences in data that you suspect are due to the IF switch (Option
001) or to RF switching, must be checked out. Refer to Chapter 5,
“Troubleshooting the Test Set” in this manual.
HP 8517B S-Parameter Test Set Manual 3-13
Performance Verification
Standard system performance verification procedures verify the operation of
an Option 001 test set used as test set number 1.
To verify the performance of a different test set in the configuration, enter its
HP-IB address (as explained in “Making Operational Checks” on page 3-13)
to select it, then continue with this procedure.
Refer to the HP 8510C On-Site Service Manual for its performance
verification procedure.
HP 8517B S-Parameter Test Set Manual 3-14
Using Anti-Rotation Clamps
During the performance verification procedure, use anti-rotation clamps to
secure RF connections at the test ports of each test set. While installed, each
clamp stabilizes the connector on RF cable to the large nut on the test set’s
RF test port. If an adapter is used, the clamp stabilizes the adapter to the
front panel RF port connector.
Without these clamps, the test port connections can loosen when a device
under test is moved. As a result, the loosening can invalidate calibrations and
measurements.
NOTE
These instructions refer to an installation using HP RF cables. However, the
anti-rotation clamps may also be used with front panel adapters. Adapter
installations are similar. There are two anti-rotation clamps included in the
test set accessories box.
Attach the first clamp
Remove one anti-rotation clamp from the accessories box. Loosen its
thumb-screw until it is nearly freed from the counter-sink socket in the
clamp body. The clamp is shown as item (5) in Figure 2-1, “Accessories
Supplied with the HP 8517B Test Set.”
1. Gently push the clamp (round-hole end first) over and past the RF cable
connector to be used.
2. Fit the rubber O-ring in the round end of the clamp over the connector.
NOTE
If the O-ring is not snug or is damaged, refer to the Chapter 6, “Replacement
Procedures” for instructions about replacing the internal O-ring.
3. Wiggle the clamp to ease it over the connector.
4. Attach the cable to the test port and tighten it as specified in the cable
manual.
NOTE
Do not twist the cable as you attach it to the test port.
Use the torque wrench supplied with your calibration kit to tighten the cable
to 90 N-cm (8 in-lb). Do not over-torque the connection. See Figure 3-5.

Troubleshooting the Test Set
The troubleshooting strategy for the HP 8517B S-Parameter test set is a
systematic sequence of procedures. The information may be used after
system-level troubleshooting has identified the test set as the problem
instrument.
Use the troubleshooting flowchart in Figure 5-2 to help isolate the faulty
assembly. Notice procedure numbers within some of the flow diagram
blocks. These are keyed to troubleshooting procedures. Perform the
numbered procedure associated with each block as you progress through the
chart.
Refer to the block diagrams, located at the end of this section, to help you
understand the test set’s operation.
HP 8517B S-Parameter Test Set Manual 5-1
Troubleshooting the Test Set
Theory of Operation
Theory of Operation
RF paths for Port 1 and Port 2 are similar. This section discusses in detail the
source power signal, as it is routed via the RF IN connector, through the test
set, and to Port 1 for S11 and S21 measurements.
Figure 5-1 Standard HP 8517B RF Block Diagram
The RF Source Power
•
RF source power enters the test set through the rear panel. The RF power
is applied to the switch/splitter (A18).
•
At the switch/splitter, the power is attenuated by approximately 7 to
14 dB, depending upon frequency.
•
The switch/splitter receives its control signals from the attenuator/switch
driver board (A5).
•
The switch part of the switch/splitter, which is a combination of two
power splitters and a solid-state switch, selects the power splitter to use
and, therefore, the test port to receive the RF power.
•
LEDs on the front panel and on the attenuator/switch driver board (A5)
indicate which test port is active.

Measurements
The Sampler Control
Switching
•
The reference signal is routed from the switch/splitter through the
20-7 dB tapered pad (AT1) to attenuate any VTO feed-through signals.
•
The signal is then applied to A10, the a1 sampler assembly, where it is
down-converted to a 20 MHz IF (intermediate frequency).
•
Because the RF power is being routed to Port 1, the a1 IF signal is used
to phase lock the network analyzer. Had the RF power been routed to
Port 2, the a2 IF signal would have been used to phase lock the network
analyzer.
•
The test signal is routed from the switch/splitter (A18) to the 60 dB
programmable attenuator (A16) for Port 1.
•
The signal may then be attenuated in 10 dB steps or passed through
without attenuation to Port 1 bias tee (A7).
•
A bias supply to provide dc voltage to Port 1 bias tee can be connected
to J8 on the rear panel of the test set, also.
•
The RF signal rides this dc level which is used to turn active devices on
(bias ON) so their S-parameters can be measured.
•
Beyond the bias tee, the test signal travels to the directional coupler
(A6).
•
At the coupler, the incident RF power is applied to the device under test.
•
The signal reflected from the DUT is separated from the signal incident
to the DUT by the Port 1 coupler (A6).
•
The reflected signal exits the coupler and is applied to b1 sampler (A12),
then is down-converted to a 20 MHz IF signal.
•
The S11 measurement is the ratio of the two IF signals from a1 and b1
samplers.
•
The incident signal is transmitted through the DUT, through Port 2
coupler, then into b2 sampler (A13).
•
The incident signal is down-converted to a 20 MHz IF so S21 can be
measured. S21 is the ratio of the two IF signals from samplers a1 and b2.
•
The samplers may be turned on and off, depending upon the parameter
being measured.
•
Sampler switching is controlled by a microprocessor on the HP-IB board
assembly (A4). The default condition (test set power ON and no HP-IB
commands sent by the network analyzer) is for the test set to be active
with the RF signal applied to Port 1.
HP 8517B S-Parameter Test Set Manual 5-3
Troubleshooting the Test Set
Theory of Operation
•
The LO Signal Control
If the test set is equipped with Option 001 (multiple test set capability),
its begin state is inactive. That is, rather than using the test set’s internal
IF, a switch is set in the test set to accept an IF from another test set.
The LO, generated by A14 VTO/driver, is phase locked to the source so the
desired VTO harmonic is 20 MHz greater than the source frequency.
The phase-locked loop includes:
•
Portions of the test set, such as the VTO summing-amp board (A3), the
VTO/driver (A14), and the a1 sampler assembly (A10), and
•
The HP 8510C Network Analyzer
The VTO summing-amp board (A3) provides control voltages to tune the
VTO to the correct LO frequency.
The VTO also has an output LENDRA (Low END of RAnge) which is
routed via the test set interconnect cable, to the HP 85102.
The LENDRA provides an indication to the network analyzer about whether
or not the VTO is operating within its normal frequency range.
If the VTO exceeds its normal frequency range, the network analyzer
displays the running error message VTO OVER RANGE.
CAUTION
Electrostatic Discharge Sensitive (ESD) Assemblies
Assemblies you might handle in these troubleshooting procedures are
extremely sensitive to damage from static electricity. They may or may not
continue to function if they are subjected to electrostatic discharge. Their
reliability, however, will be impaired.
