POWER LEVEL ACCURACY

VERIFICATION

AND FLATNESS TESTS

Power Level Power level accuracy is tested by stepping the out- Accuracy Test put power level down in 1 dB increments from its

Procedure maximum rated power level and measuring the out- put power level at each step.

1. Set up the 682XXB/683XXB as follows:

a. Reset the instrument by pressing SYSTEM , then Reset . Upon reset, the CW Menu is dis- played.

b. Press Edit F1 to open the current frequency parameter for editing.

c. Set F1 to the CW frequency indicated on the Test Record.

d. Press Edit L1 to open the current power level parameter for editing.

e. Set L1 to the power level indicated on the Test Record.

2. Measure the output power level with the Power Meter and record the reading on the Test Record.

3. On the 682XXB/683XXB, use the cursor control key (diamond-shaped key) to decrement L1 to the next test power level on the Test Record. Measure and record the Power Meter reading on the Test Record.

4. Repeat step 3 for each of the test power levels listed on the Test Record for the current CW fre- quency.

5. Repeat steps 1 thru 4 for all CW frequencies listed on the Test Record.

Power Level Power level flatness is tested by measuring the out- Flatness Test put power level variation during a full band sweep;

Procedure first in the step sweep mode (682XXB/683XXB mod- els), then in analog sweep mode (683XXB models only).

1. Set up the 682XXB/683XXB as follows for a step sweep power level flatness test:

a. Reset the instrument by pressing SYSTEM , then Reset . The CW Menu is displayed.

b. Press Step to place the signal generator in the step sweep frequency mode and display the Step Sweep Menu.
