2.With no signal at spectrum analyzer's INPUT 5052, measure and record offset voltage at (AUX A) VERTI- CAL OUTPUT connector.

3.Connect equipment as shown in Figure 4-22. Set step attenuator to 0 dB.

4.Set spectrum analyzer's Amplitude Scale to 10 dB/DIV and adjust TUNING control to center signal on CRT display.

5.Set spectrum analyzer's FREQ SPAN/DIV control to zero (0), VIDEO FILTER full CW (not in detent), and RESOLUTION BW control to 1 MHz. Adjust TUNING control for maximum reading on DVM.

6.Set signal generator OUTPUT LEVEL control for DVM reading of (+ 800 mV + offset (step 2) f0.5 mV). Trace should be approximately at top CRT graticule line.

7.Record DVM readings for step attenuator settings, from 0 dB through 70 dB, in Table 4-16.
