Measures on the DRIVER card.
Rotate the power regulation trimmer on the control unit completely in clockwise
sense: this allows that the VPAarrives to approximately 50.2 Volt, then check that
the relays work acting on the dip-switches.
Verify that there is Gate voltage in the module driver section, and bring it to 2.5
Volt through the trimmer.
Voltage measures on the BIAS card.
Measure the voltage on the pin 2 of U4, remove 500 mV and move the comma to
a space to left, bringing back the resultant value on TR5 of the CPU like
Temperature. Example: if the measured voltage is 721.0 mV, removing the 500
resulting 221,0: moving the comma to left of a cipher result 22,1; in degrees.
Be turned on the module acting on the ON/OFF switch of the control unit and
measure the VPA value on the pin 1 of CN4, bringing back the value on the
computer acting on TR9 of the CPU.
Setting of the BIAS Voltage and of the Finales current.
Interposing an amperometer between the VPA voltage (red cables of power) and
the MosFet source, act on the pallet’s trimmer up to obtain 20 mA of current.
With the help of an electronic load set the current of the current measurers of the
finals and of the driver.
For the finals are made absorb 8A from each channel setting the load between
GND and the supply wire of the pallet bring back the respective current on the
computer acting on the TR11 for the pallet, TR2 for the pallet 2, TR3 for the pallet
3 and TR8 for the pallet 4.
For the driver are made absorb 1.2 - 1.3Abetween GND and pin of the rear of the
fuse carrier FS1, (you must get away the fuse carrier of the driver) bringing back
the reading on the PC through TR10. Is recommended give between 4 and 5 turns
in counterclockwisesenseatTR10 before apply the load, avoidingthatthemodule
enters protection, delaying the testing.
Switch off power putting the switch on the control unit Stand-By, and connect the
power wires of the pallet and the fuse carrier of the driver.

Acting on the power regulation PWR, checking the current, the harmonicses and
the Pout, make go up the power up to 400 W, with the tester setted with full scale
at mV. With the metal point on the pin 4 of CN3 on the bias card, trying to set to
zero the measure most possible, acting through a non-metallic screwdriver on the
trimmer more to left (toward the flank) that is situated on the measure card of Pout
placed at the end of the filter, doing attention that the tester probes are to the
outside of the module avoiding the interference of the RF on the measure. Then
switch off the pilot and the H.T., carry the tester on the measure of Ohm, and
measurethevalueofthistrimmerbringsbackitonthetrimmermoretothe internal.
Thisprocedure is inclined todelineatethe reading of theprobesof Forward Power
Output and Reflected Power Out.
Maintaining the pilot to 98 Mhz, carry the Pwr Out up to 1 kW. Bringing back the
value of the bolometer on the TR1, then set the Pwr In on the TR6 to 4.8W, and
finally equalize the mosfet current acting on the bridges of the pallet and on the
bias resistances.
Carry the working frequency to 87.5 MHz, go up to 800 mW. Act on the power
regulation RV2 that is placed on the driver card and obtain 1kW of Pwr Out. Bring
back all the measures on the test tables of the computer and register it.
Then report the measures for the other working frequencies, 98 and 108 MHz,
registers it too.
For all the frequencies, check that it is possible come at least to 1150 W of power.
Always to 98 Mhz. Connect a halved load to the ouput of the module and go up
with the pilot up to read 90 Wtt of reflected power, act on the TR6 up to that the
measure on the Bird doesn't level with the reading on the computer.
Then restored the load, go back to do the Pwr Out reading to 98MHz arriving to 1
kW and register it on the computer.
Withdraw the voltages measures of the bias, of the mosfet, of the pallet and of the
driver, give a serial number and save the data on the computer.
Finally remove the coaxial cable from the withdrawal of the Bird and put it on the
withdrawal that is situated on the module frontal and set the 10 Dbm acting on the
device on the output board.
