MODEL 8559A PERFORMANCETESTS

PERFORMANCE TESTS

4-15.RESOLUTIONBANDWIDTH ACCURACY (Cont'd)

PROCEDURE:

Part of this test must be performed with power supplied to the instrument and with protective covers removed. The test should be performed only by sewice-trainedpersonnelwho are aware of the hazards involved.

1. Set equipment controls as follows:
Spectrum Analyzer:
FREQUENCYBANDGHz	..................................................	.01-3
TUNING ..............................................................	0.035GHz
FREQSPAN/DIV ...............................................................		0
RESOLUTIONBW .........................................................		3MHz
INPUTATTEN .............................................................		10dB
REFERENCELEVEL .......................................................		OdBm
REFLEVELFINE ..............................................................		0
AmplitudeScale ..............................................................		LIN
SWEEPTIME/DIV ........................................................		AUTO
SWEEPTRIGGER .....................................................	FREERUN
ALTIF .....................................................................		OFF
SIG IDENT .................................................................		OFF
BLCLIP ....................................................................		OFF
VIDEOFILTER .............................................................		OFF
Signal Generator:
COUNTERMODE ..............................................	INT,EXPANDXlO
AM ........................................................................		OFF
FM ........................................................................		OFF
FREQUENCYTUNE ......................................................	35MHz
RF ..........................................................................		ON
OUTPUTLEVEL ..........................................................		OdBm

2.Connect equipment as shown in Figure 4-9.

3.Adjust spectrum analyzer TUNING control to locate peak of 35-MHz signal on CRT. Reduce signal generator output if necessary.

NOTE

If necessary, select 10 dBlDlV to locate signal, then switch to LIN.

4.Adjust signal generator OUTPUT LEVEL to position trace at 7.1 divisions above graticule baseline.
