9.Key in (SWEEP TIME] 5 ms and set function generator for a counter reading of 2.00 f0.02 kHz.

10.Adjust spectrum analyzer TRIGGER LEVEL to place a peak of the triangular waveform on the first graticule from the left edge of the CRT display as a reference. (Adjust function generator amplitude, if necessary, to provide a signal large enough to produce a stable display). The fifth peak from the reference should be within ~l~0.5 division of the sixth graticule from the left edge of the display (see Figure 2-34).

11.Using sweep times and function generator frequencies in

Table 2-18, check sweep time accuracy for sweep times ~20 ms by procedure of step 10.
