TB 9-6625-2259-24
Weak in power.
Pop up abruptly.
Track oppositely to fundamental and harmonic signals.
Disappear abruptly.
(7) Press LEVEL key and set LEVEL display to +10 dBm by pressing 10 with
DATA ENTRY keys and then by pressing GHz/dBm/SEC DATA ENTRY key.
(8) Press FREQUENCY RANGE CW F1 key and set F1 M3 display to 2.000 GHz
by pressing 2 with DATA ENTRY key and then by pressing GHz/dBm/SEC DATA
ENTRY key.
(9) Adjust spectrum analyzer controls as necessary to view TI 2.000 GHz signal at
center graticule line of spectrum analyzer display.
NOTE
Adjust spectrum analyzer FREQUENCY RANGE controls as
necessary to view fundamental frequency from 2 to 18 GHz for
(10) below.
(10) Slowly rotate INCR-DECR control cw (from 2.000 to 18.000 GHz) and observe
non-harmonic related (spurious) signals. Spurious signals will be <-45 dBc (45 dB below
carrier level indication on spectrum analyzer).
b. Adjustments. No adjustments can be made.
11. Residual AM Test
a. Performance Test
(1) Press TI RESET key.
(2) Connect measuring receiver power sensor to RF OUTPUT 50 .
(3) Press LEVEL key and set LEVEL display to +13 dBm by pressing 13 with
DATA ENTRY keys and then by pressing GHz/dBm/SEC DATA ENTRY key.
(4) Press FREQUENCY RANGE CW F1 key set F1 M3 display to 0.010 GHz by
pressing 10 with DATA ENTRY keys and then by pressing MHz/dB/mS DATA ENTRY key.
(5) Configure measuring receiver to measure frequency and allow measuring
receiver to acquire carrier frequency.
(6) Configure measuring receiver to measure AM depth with no high pass filter,
300 kHz low pass filter and RMS detector selected. Measuring receiver indication will be
within limit specified in first row of table 4.
(7) Repeat technique of (4) through (6) above for remaining frequencies in table 4.
Measuring receiver indication will be within limit specified in table 4.
