Procedure

Sweep Times 220 ms 1. Connect equipment as shown in Figure 2-4.

2.Press [INSTR PRESET) on the spectrum analyzer.

3.Key in the following settings:

(	C E N T E R F R E Q U E N C Y	)	500 MHZ
			0 kHz
[	F R E Q U E N C Y S P A N ]

4.Set up the universal counter as follows:

a. Set all front panel keys in “out” position. b. Set POWER switch to ON.

c.Set GATE TIME vernier control to 9 o’clock. d. Set SEPXOM A switch to COM A position.

e. Depress T.I. A + B switch (making sure the blue shift key is out).

f. Set Channel A trigger level to trigger on negative slope. g. Set Channel B trigger level to trigger on positive slope. h. Set both Channel A and Channel B ac/dc switches to de.

i.Connect the digital voltmeter to Channel A TRIGGER LEVEL OUT. (Be sure to ground the DVM properly.)

j. Adjust Channel A trigger level to set a DVM voltage reading of 0.3 v.

k. Repeat steps i and j for Channel B.

5.Set analyzer @WEEP TIME) to 20 ms. Allow the universal counter enough time to settle at this sweep time.
