(e)
MODE switch to CW.
(f)
The four paddle switches to their extreme down positions.
(g)
MARKERS MHz 50 Har pushbutton pressed in (all other pushbuttons out).
(h)
Set CENT FREQ to 300 MHz.
NOTE
TI should be stabilized with ac power applied for 15 minutes
before making the following measurements.
NOTE
Enter 32.0 SPCL (0.01 dB resolution) on measuring receiver
and utilize for all RF measurements.
(2) Connect measuring receiver power sensor module to TI RF OUT.
(3) Using measuring receiver and RF power measurement techniques in Log Mode,
measured power will indicate between +9.5 and +10.5 dBm, if not, perform b below.
(4) Set OUTPUT vernier to 0 dBm.
(5) Measuring receiver will indicate between -0.5 and +0.5 dBm.
(6) Set OUTPUT vernier to -10 dBm.
(7) Measuring receiver will indicate between -9.5 and -10.5 dBm.
(1) Set OUTPUT to +10 dBm.
(2) Adjust M10H LEVEL MAX until measuring receiver indicates +10 dBm (R).
(3) Adjust OUTPUT vernier to -10 dBm (fully ccw).
(4) Adjust M10H LEVEL MIN until measuring receiver indicates -10 dBm (R).
NOTE
Some interaction exists between LEVEL MIN and LEVEL
MAX controls, so repeat the adjustment until both the +10 and
the -10 dBm readings are obtained.
12. RF Output Flatness
a. Performance Check
(1) Set MODE switch to CW.
(2) Connect measuring receiver power sensor module to TI RF OUT.
(3) Set OUTPUT switch to +10 dBm.
(4) Adjust CENT FREQ controls slowly across the entire band (10-500 MHz).
(5) Using measuring receiver and tuned level techniques in log mode, note
frequency where maximum output is obtained.
(6) Adjust CENT FREQ to frequency noted in (5) above.
(7) Adjust OUTPUT vernier control until measuring receiver indicates +10 dBm.
