PROCEDURE:
Set spectrum analyzer controls as follows:
FREQUENCYBANDGHz ..................................................	.01-3
TUNING ..............................................................	0.035GHz
FREQ SPAN/DIV .........................................................	200 kHz
RESOLUTION BW ...................................	OPTIMUM, coupled (pushed in)
INPUTAlTEN .............................................................	10dB
REFERENCE LEVEL ....................................................	- 10 dBm
REFLEVELFINE ..............................................................	0
Amplitudescale ........................................................	10dB/DIV
SWEEPTIME/DIV ........................................................	AUTO
SWEEPTRIGGER .....................................................	FREERUN
ALTIF .....................................................................	OFF
SIG IDENT .................................................................	OFF
BLCLIP ....................................................................	OFF
VIDEOFILTER .............................................................	OFF

Connect CAL OUTPUT signal of spectrum analyzer to INPUT 5W. Adjust TUNING control to position signal at center graticule line of display. Adjust FREQ CAL potentiometer for a FREQUENCY GHz display of 0.035.

Connect comb generqtor to spectrum analyzer INPUT 5W as shown in Figure 4-4.
Set comb generator controls as follows:
COMB GENERATOR - MHz ................................................	10 MC
INTERPOLATION AMPLITUDE - 1 MHz ......................................	OFF
OUTPUT AMPLITUDE ..............................................	Full clockwise

Adjust spectrum analyzer TUNING control to center 10-MHz comb tooth. FREQUENCY GHz readout should indicate:

Min. Actual Max.

Set comb generator COMB FREQUENCY - MHz for 100 MHz comb. Set spectrum analyzer FREQ SPAN/DIV to 1 MHz, and adjust TUNING control to position 1.5-GHz comb tooth at center graticule line of display. FREQUENCY GHz readout should indicate:

Min. Actual Max.

Connect sweep oscillator to spectrum analyzer INPUT 5W as shown in Figure 4-4.
