PROCEDURE:

1.	Set equipment controls as follows:
	Spectrum Analyzer:
	FREQUENCYBANDGHz ..................................................	.01-3
	TUNING .............................................................	>O.OlOGHz
	FREQSPAN/DIV ...............................................................	0
	RESOLUTIONBW .........................................................	lkHz
	INPUTATTEN .............................................................	10dB
	REFERENCELEVEL .......................................................	OdBm
	REFLEVELFINE ..............................................................	0
	Amplitudescale ........................................................	10dB/DIV
	SWEEP TIME/DIV ........................................................	AUTO
	SWEEPTRIGGER .....................................................	FREERUN
	ALTIF .....................................................................	OFF
	SIGIDENT .................................................................	OFF
	BLCLIP ....................................................................	OFF
	VIDEO FILTER .........................................................	12 o'clock
	Signal Generator:
	COUNTERMODE ..............................................	INT,EXPANDXlO
	AM ........................................................................	OFF
	FM ........................................................................	OFF
	FREQUENCYTUNE ....................................................	21.4MHz
	RF ..........................................................................	ON
	OUTPUTLEVEL .......................................................	z - 3dBm
2.	Connect equipment as shown in Figure 4-1 1.

NOTE

For early instruments that do not feature A16J3, a 321.4 MHz, - 25 dBm signal can be injected directly into the input of Third Converter Assembly A10 at blue cable A1OW1. Set signal generator COUNTER MODE to EXPAND XI00 (most significant digit will overflow).

3.Adjust signal generator frequency until spectrum analyzer trace is at peak. Put signal generator OUTPUT LEVEL to position trace at top graticule line.

4.Tune signal generator until trace drops to 2 divisions above graticule baseline. Record signal generator frequency.
