EQUIPMENT DESCRIPTION
GENERAL
The SAlP 750 is a single channel processor in the 750 Series of professional quality channelized output
headend products. The SAIP Series are input frequency agileTV channel processors that provide visual and
aural RF carrier outputs on individual Broadcast or CATV channels in the full 750 MHz output frequency
range. The processor mainframe (Stock No. 5885) contains the linear power supply, the fully agile RF to IF
A input converter and the fully agile iF to RF output converter. A low cost removable single channel output
illter modUle provides exceptionally low out of band noise that permits the construction of multiple channel
headends without auxiliary filtering. The output modules are availble in +40 dBmV and +60 dBmV
versions.The 7984 (+40 dBmV) and the 7995 (+60 dBmV) modules are ordered by the CATV output channel.
The U7984 and the U7985 models are ordered by the UHF output channel.
Efficient AGC assures a wide dynamic mnge and dual SAW filters provide superior selectivity. DIP switches
for setting the input frequency are accessible trom the front panel, as are the AN ratio and output level
control. Two tuner lF flatness controls are located adjacent to the input dip switches.The output frequency
dip switches are set internally corresponding to the channel of the output filter module installed.
An extemai iF Icop-thru enables the replacement oi the standard lF signal with an alternate source at
composite lF (such as an all-call system) or the insertion of IF scrambling equipment An on-board carrier
substitution generator is automatically activated upon loss of input signal.
ELECTRICAL
A block diagram of the SAIP is shown on page 2.. All primary processor functions are carried out on three
printed circuit boards. The input Converter PCB selects and converts the incoming RF signal to the IF
treCerncy, then filters and provides a gain control signal back to the input amplifiers, The Output Converter
PCB convene the lF signal to the final RF frequency. The Output filter module amplifies the chosen channel
and bandpass filters the signal.
On the Input Converter PCB, the RF signal is applied to a PLL controlled (set by DlP switches) UHF/ VHF/
CATV tuner. The 41 to 47 MHz lF output from the tuner is amplified and filtered by two SAW tilters. The
resulting signal I5 SEflSEd W a dEtECIOI' that dGVQIOPS an AGC voltage to control the gain of the tuner and IF
amplifier, The resuhing lF output level is steady regardless of changing input levels. The absence of an
incoming signal activates an oscillator that substitutes an Uri—modulated signal at the iF visual carrier
irequency.
The ll= carriers are exlemally looped lo the synthesized upconverier boardrThe crystal controlled synthe-
sized oscillaior frequency is selected via dip switches. Positive or negative offsets of 12.5 kHz or 25 kHz may
be applied via the internal dip switches. The double balanced mixer output is amplified and coupled with 12
Vdc for connection to lhe Oulput Filter Module (sleek $7984 or 7985).
The channelized Output Filler Module receives the RF signal from the upconverter where it is amplified and
bandpass filtered. A mulil-lum bridge-T attenuator assures flat level adjustment and excellem return loss to
the final drive amplifier. A low loss two siage bandpass filter follows the final amplifier for maximum out of
band carrierto noise performance.

Figure 4 Internal Processor Connections
PROCESSOR INTERNAL CONNECTIONS AND CONTROLS
Figure 4 shows the processor with the cover removed. One unique feature of the processor is the
channelized output filter module (OFM).The excellent out of band carrier to noise an be attributed to
the OFM. Output channel selection is made by replacement of the OFM and selection of the
Upconverter dip switches. With the cover removed, the OFM can be replaced by loosening the two 'F"
cables and removing the two screws securing the OFM to the front of the chassis and two screws
securing the OFM to the inner chassis.
OUTPUT FRE ZUENCY OFFSETS
Off air television signals may have offsets when two transmitters of the same channel are within the
range of interference. For example San Diego channel a and Tucson Channel 3 have 10 kHz
offsets; Tucson +10 kHz. San Diego -10 kHz.
When converting to an output channel in the aeronautical band, offsets of either 12.5 kHz or 25
kHz are required.The table on pages 14 to 16 llsts the output converter switch settings for the
standard cable TV and broadcastTV channel assignments. 0= UP = OFF (as labeled on the
twitch). The L0 frequency is the sum weighting of the switches in the UP position. i 2.5 kHz
offsets can he made by adjustment of C4 on the Upconverter Assembly. The weighting of the
specific switches are provided below:
Switch Bank 1 Switch Bank 2
Switchtf Weight Switch# Weight Switchff Weight Switcht Weight
1 0.8 MHZ 6 25.6 MHz 1 VCO BandSwitch 5 50 kHz
2 1.6 MHz 7 51.2 MHz 2 VCO BandSwitch 6 100 kHz
3 3.2 MHZ 8 102.4 MHZ 3 12.5 kHz 7 200 kHz
4 6.4 MHz 9 204.8 MHz 4 25.0 kHz 8 400 kHz
5 12.5 MHz 10 409.6 MHZ
To obtain a +125 kHz offset, move Switch Bank 2, switch its UP. If the switch Is already in the UP
position, move Switch Bank 2, switch #4 UP at move Switch Bank 2, switch #3 DOWN. (This adds
25 kHz and subtracts 12.5 kHz.)
PREPARATION FOR USE
Plug in the 3-prong mnnector of the AC power cord into a suitable 117 V 60 Hz AC outlet of adequate
current carrying capacity. Use appropriate cables (75 Ohm coaxial) to connect the RF Signal source to the
RF input of the unit and the RF output of the unit to the system input. Make sure that the IF coaxial jumper
cable is in place, connecting the iF input and the IF output.
OPERATlON
INPUT CHANNEL SELECTION
Gently pull both retaining clips of the left side access door simultaneously to expose the channel selector
switches. Using an appropriate tool (or a ballpoint pen) set each individual switch of both DlP switches (a
total of 16) either UP or DOWN according to one of the applicable lNPUT channel charts (Standard, HRC or
UHF) in this manual. After setting, re-secure the access door to prevent inadvertent tampering and/or
possible ingress of dust and dirt.
OUTPUT CHANNEL SELECTION
The output channel is factory preset to the output channel ordered. Changing the output channel requires
replacement of the Output Filter Module (stock $7984, U7984, 7955 or U7985).The filter is ordered to the
desired output channel. inside the cover the upconverter dip switch settings must be changed to correspond
to the settings identified on the Output Filter Module.The dip switch settings may also be found on pages 14
through 16 of this manual.
ADJUSTMENTS
OUTPUT LEVEL . Connect a suitable RF indicator such as a Field Strength Meter (tuned to the visual
carrieffrequency) or a Spectrum Analyzerto the RF output of the modulator or a
system monitor point and adjust the Output Level control for the required reading of
video carrier amplitude.
AN CARRIER RATIO - To adjust the aumi-tovisual carrier ratio. tune the RF indicator device to the aural
center frequency and adjust the Aural Level control to obtain the desired aural carrier
level. Note that you cannot obtain a ratio smaller (that is, the aural level relatively
higher) than that of the incoming RF signal. Recommended ratio is 45 dB.
FREQUENCY OFFSEl‘S - if the chosen output channel of the processor is subject to FCC mandated
aeronautical offsets (see the output frequency settings charts on pages 14 through
16) adjustment of the output upconvenerfrequency may be required.The reason
that adjustment may be required is due to possible offsets on the input channel.
SomeTV stations across the USA are offset by either+10 kHz or -10kl—lz.
BLONDER TONGUE sets the output upconverter frequency based upon no input
offset.
The following procedures require that the unit be powered for 30 minutes priorto making adjustments.
FREQUENCY RESPONSE -The frequency response adjust commie are factory set for optimum response over
all input channels. However, channel flatness can be improved for a particular input!
output channel combination by adjusting front panel controls R66 and R70.
1. Tune the SAiP Processor to the desired input channel.
2. Using proper flatness measurement equipment, observe the channel
flatness.
3. Slightly adjust the front panel control R66 on the left and observe the
flatness. R66 controls the flatness amplitude at the frequency set by R70, the pot
next to the dip switch. it the flatness does not improve, adjust R70 then vary R65
while observing the RF flatness.
STANDBY CARRIER
THRESHOLD -
The Standby Carrier Threshold is factory-set for 45 dBmV. it it is necessary to
set the threshold to some other level, proceed as follows before installing the
SAIP Processor in its rank or cabinet.
1. Tune the SAIP Processor to the desired input channel.
2. Connect a television receiver (tuned to the output channel) to the rear‘penel
RF OUT terminal; use the RF OUT control and attenuators as required to avoid
overioacting the receiver.
3. Using a variable attenuator and a signal level meter, adiust the input signal to
the desired threshold level. Connect the input signal to the HF INPUT terminal.
4. Refer to the Figure below and locate the Threshold Control, R32.
5. Adiust R32 so that the picture just switches hetween the input signal and the
standby carrier. Use the television receiver as an indicator.
6. After making the adjustment, disconnect the power cord and input and output
cabling.
7. Install the unit in its mounting location.

STATIC 1, EQUIPMENT 0: sun: vs Sensitive devicu...
Care mustbe taken atall times because this equipment contains staticsensifive CMOS and FET devices. Here
is a brief tutorial on static, particularly pertinent to CMOS and other MOS device handling:
1.
It is important to avoid surroundings or situations in which static can be generated. The builtflng floor
should have grounded conductive floor coverings. or a grounded conducive mat placed on the liner
in front olthe bench. Then, the bench itself should also have a grounded conductive met on which the
equipment is placed. Anybody working on the equipment should wear either a grounded wrist strap
(preferably) or condudive overshoes. Vacuum cleaner tools should all be conducive and grounded
to avoid static from air motion. (Vawum cleaners made for computer servidng would be suitable).
Soldering iron tips must be grounded. Use property maintained soldering equipment that has a three
wire, grounding plug, verifying low path resistance between ground and the tip with an ohn‘meter every
one this equipment is used.
The average person wearing rubber-soled shoes and walking across a woolen or synthetic mrpet or
untreated vinyl tiled floor is able to generate voltages in excess of 15 to 20 w. Most MOS devices will
suffer puncture of the oxide insulating their gates. at 20 to 40 V. Many CMOS devices are fabricated
with built~in zeners which will clamp foreign voltages, but the amount of energy that must be dissipated
may easily exceed the rating of this protedion. It is therefore pmdent to assume that little or no static
protection exists in a CMOS device and therefore you must provide your own.
A typical unprotected gate of a CMOS logic K: has an input capacitance of about 5 pF and can
self-immolateatzo V, someenergytodestroymelCisgivenbytheexpressionW=CVQwhereW
is in watt-seconds, c is in farads. and V is in volts. One watt-second is also known as a Joule.
Substituting numeric quantities results in W = 5 x10" x 20 x 20 + 2 = 1 x10“ Joule pergate. Stored
energy in the approximately 100 pF capacitance ottne human body charged to 15 kV, becomes W =
100x1t7"z x 15000 x150004-2 = 11.25 x 1th"l Joule. Eleven ands quertermllllonflmesmoleenergy

annihilate more than eleven million CMOS gate cadet all at once.
Tt'n‘s is serious stuff. To avoid destroying CMOS devices, the human body must be grounded tlrst. That
is the reason for all the “grounded surroundings" we suggest in paragraph 1. Don't forget. though. that
a circuit board has conductive metallic paths connecting into the CMOS parts, whidt makes them all
susceptible to mass devastation as easily as would be the destruction of any one CMOS chip all by
ltself. Amys gmund yourseltfirst then the board.
Avoidance of stefic exposure of boards and CMOS devices is easier. Ensure that boards are always
kept In conductive bags or boxes when not in place in the equipment. and that spare CMOS le are
in conducfivechlpwriersorpluggedintocmduotivefoam Bowelulaboutthispoint; manyplastic
foams can be coloured black, but may still be an insulator. Use your ohmmeterto be sure.
Don't swept any devices whose pins are punched through alurrinum toil lnto loam plastic People who
don't know better have used this rmthod for shipment and storage of devices, but it cannot be
depended upon. because many times the holes made in the foil by the device pins become enlarged
simply from the motion of pressing the pins into the foam, and won't make contact any longer, When
thedevice iswithdlawn from thefoam, lhet'ridion otthe plasticegainstthe pin cengenerateenouyi
marge to cause puncture and consequent failure ofthe CMOS gate insulation.
Identical statements to those made in the above paragraphs apply to RF power MOSFETs, and
although the gates of these devices might appear to be considerably more robust than those of the
average CMOS logic device, this is due only to the much greater gate area and consequently greater
inputmpadtance. The same order of magnitude of gate oxide breakdown voltage eao'sts for RF power
FET s as tor small CMOS devices. therefore use the same order atlare in handling.

Keep FETs in their anti-static containers until ready to install. The module and the teetmioien should
both be earthed/grounded Observe the handling procedures dismssed in Part7 above. includ'ng the
use of antistatic bench coverings. conducive overshoes, gromded wrist straps. etr.

When all holes are lined up properly, carefully finger-lighten the two screws and spring ioolwreeherst
Torque the clamping bridge screws evenly to 4.5 inch-pounds. This amount is recommended by the
FET manufacmrer to allow for thennei expansion of the device, 4.5 inch-pounds also will avoid the
possibility of strtpping the threads in the heelsink, or breatt‘ng the screws. Use only the spade!

Ensure that the pressure plate is centered evenly, between the clamping bn'dge and the FET, and
tighten the grub screw. Torque it also to 4.5 molt-pounds.
Solder each tab to the board in turn, using a solder-pick tool to hold each tab in oonteotwith the board
while soldering; apply anoth heat to ensure that the pretin solder on the boards flows, and apply just

We mentioned this procedure during step T above as well, because some droumstances may make
it simplerto set the bias irl a High Band PA before replacing L9. When L9 is in place, each half of the
stage will need to be adjusted oonwrrentty with a bias short on the opposite side (to turn off the side

Power requirements for the 1 Watt VHF Translator were determined as follows:
1. The translators visual power meter measures the peak visual power by reading the average
levels of a detected sample of the output. The meter is calibrated by multiplying the above
visual power reading by 16896. The visual metering circuitry has a neflllglble response to the
aural power due to the large (>10MHz) deteaor bandwidth. When the detedor bandwidth is
this large, the detector does not peak detect the intercanier beat product.
2. The aural power is measured by reading the peak level of the detected 4.5MHz interoan'ier
product. The level of this product has a direct correspondence to the aural power level and is
independent of the visual power as long as the peak visual power exceeds the aural power.
This is always true for normal operation.
