Set step attenuator to 0 dB and use spectrum analyzer TUNING control to center 30 MHz signal from signal generator on CRT display. Set FREQ SPAN/DIV to 20 kHz, RESOLUTION BW to 10 kHz, and Amplitude Scale to 1 dB/DIV.

Adjust signal generator OUTPUT LEVEL control to position peak of signal seven divisions above graticule baseline.

Set step attenuator and INPUT A m E N control to settings indicated in Table 4-9.For each setting, record deviation of signal peak from referencegraticule line set in step 3.

NOTE

The REFERENCE LEVEL control setting changes by 10 dB for every 10-dB change in INPUT ATTEN. Do not change the REFERENCE LEVEL setting after changing the INPUT ATTEN setting.
