MODEL 8559A
RESOLUTION BANDWIDTH 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-trained personnel who are aware of the hazards involved.
1. Set equipment controls as follows:
Spectrum Analyzer:
TUNING
RESOLUTIONBW
INPUTATTEN
REFERENCELEVEL
REFLEVELFINE
Amplitude Scale
SWEEPTRIGGER
ALTIF
SIG IDENT

FM
FREQUENCYTUNE
RF
OUTPUTLEVEL
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.
If necessary, select 10 dBlDlV to locate signal, then switch to LIN.
Adjust signal generator OUTPUT LEVEL to position trace at 7.1 divisions above graticule baseline.
