(18) Set synthesized signal generator to sweep from 0.01 to 2.2 GHz and a sweep
time of 99 s. Observe power meter indication to ensure output remains constant.
Frequency deviation from the mean will not exceed 1.5 dB.
(19) Press FREQUENCY RANGE pushbutton for crt indication of 1.7-5.5 GHz.
(20) Adjust FREQUENCY control for 2.0 GHz indication on crt and FREQUENCY
SPAN/DIV control to 100 MHz.
(21) Adjust synthesized signal generator for 2.0 GHz signal and adjust PEAKING
control for maximum amplitude on crt.
(22) Adjust FREQUENCY control to move signal to far left graticule line and press
MAX HOLD pushbutton on.
(23) Adjust synthesized signal generator to sweep from 2 to 3 GHz. Amplitude
deviation output will not deviate more than 2.5 dBm (from the mean average).
NOTE
If any segment or portion of the span fails to meet the 2.5 dB
specification, tune the frequency to the center of this portion,
apply a cw marker at the center frequency and readjust the
PEAKING control for maximum response on crt. Decrease the
FREQUENCY SPAN/DIV control to display that portion and
then recheck frequency response.
(24) Connect power meter recorder out (rear) to synthesized signal generator
External ALC IN.
(25) Press MAX HOLD pushbutton to off.
(26) Adjust FREQUENCY SPAN/DIV control to 100 MHz and FREQUENCY
control for 3.0 GHz indication on crt.
(27) Adjust synthesized signal generator for 3.0 GHz signal and adjust PEAKING
control for maximum amplitude on crt.
(28) Repeat technique of (21) and (23) above for frequencies of 3 to 4 and 4 to 5 GHz.
Amplitude deviation will not exceed 2.5 dB indication on crt.
(29) Press MAX HOLD pushbutton off and FREQUENCY RANGE pushbutton for
a crt indication of 3.0-7.1 GHz.
(30) Adjust synthesized signal generator for 5.0 GHz (using TI controls, center 5 GHz
signal) on crt and adjust PEAKING control for maximum signal amplitude on crt.
(31) Press MAX HOLD pushbutton to on.
(32) Adjust FREQUENCY SPAN/DIV control to MAX and adjust synthesized signal
generator to sweep from 3.0 to 7.1 GHz. Amplitude deviation will not exceed 2.5 dB
indication on crt (from the mean average).
(33) Press MAX HOLD pushbutton to off.
