PULSE MODULATION TESTS:

VERIFICATION

RISE TIME, FALL TIME, OVERSHOOT, AND LEVEL

3. On the 682XXB/683XXB:

a. Press MODULATION , then Pulse to go to the Internal Pulse Status Menu display.

b. Press Edit Width and set W1 to the pulse width noted in the Test Record.

c. Press On/Off to turn on pulse modulation.

4. On the Oscilloscope, observe that the nominal level of the displayed pulse peak has shifted ver- tically, slightly off of the centerline. It may be necessary to readjust the scope trigger level.

5. On the 682XXB/683XXB:

a.Press CW/SWEEP SELECT to return to the CW Menu display.

b. Record the value of the output level L1, shown in the Level display area, on the Test Record.

c. Press Edit L1 and adjust the power level until the nominal peak level is evenly centered on the display centerline reference.

d. Record this value of the output level L1 on the Test Record.

6. Subtract the L1 reading recorded in step 5.d from the reading recorded in step 5.b. This is the pulse level error. Record it on the Test Record.

7. On the 682XXB/683XXB:

a. Press Edit L1 and set L1 to the maximum lev- eled output power level for the instrument be- ing tested (refer to Table 3-2, page 3-6).

b. Press MODULATION , then Pulse to return to the Internal Pulse Status Menu display.

c. Press On/Off to turn off pulse modulation.

8. Repeat steps 1 through 7 for any other frequen- cies and pulse widths noted in the Test Record. Record the results on the Test Record.
