(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 fundamental signal near
center graticule line on spectrum analyzer display.
NOTE
Adjust spectrum analyzer controls as necessary to view
fundamental, second harmonic and subharmonic signals for
(10) below.
(10) Slowly increase TI frequency to 18.000 GHz by rotating INCR DECR
control cw. Maintain signal near center graticule line of display with spectrum analyzer
controls. Second harmonic amplitude on spectrum analyzer display will be less than -25
dBc (25 dB below carrier level indicated on spectrum analyzer display) and subharmonic
amplitudes will be less than -25 dBc (25 dB below carrier level indicated on spectrum
analyzer display).
b. Adjustments. No adjustments can be made.

to spectrum analyzer INPUT 50
(2) Connect RF OUTPUT 50
(3) Press 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 and set F1 M3 display to 0.010 GHz
by pressing 10 with DATA ENTRY keys and then by pressing MHz/dB/msec DATA
ENTRY key.
(5) Adjust spectrum analyzer controls to view TI 10 MHz signal at center graticule
line of spectrum analyzer display.
NOTE
Adjust spectrum analyzer FREQUENCY RANGE controls as
necessary to view TI fundamental frequency from 10 MHz to 2
GHz for (6) below.
(6) Slowly rotate INCR DECR adjustment control cw (from 0.010 to 2 GHz) and
observe non-harmonic related (spurious) signals. Spurious signals will be <-45 dBc (45 dB
below carrier level indication on spectrum analyzer).
NOTE
Spurious signals may be characterized as listed below:
