Operation Verification

Checking the Maximum Leveled Power

Perform the following procedure to check the maximum leveled power:

1.	Press Preset.
2.	Attach a 50Ω load to the RF OUTPUT. A power sensor, attenuator, or 50Ω termination is an example of
	a 50Ω load.

3.Press RF On/Off. The RF On annunciator is now displayed.

4.Press Mod On/Off. The Mod Off annunciator is now displayed.

5.Press Amplitude and enter a value from Table 3-1that is applicable to your model and options.

6.If the E82x7D PSG signal generator is equipped with Option 007, press Sweep /List > Sweep Type> Step > Configure Step Sweep.

If the E82x7D PSG signal generator is not equipped with Option 007, press Sweep /List > Configure Step Sweep.

7.Press Freq Start and enter the start frequency value listed in Table 3-1that corresponds to the amplitude value entered in step 5.

8.Press Freq Stop and enter the corresponding stop frequency listed in Table 3-1.

9.Press # Points and enter the number of corresponding points listed in Table 3-1.

10.Press Return > Sweep > Freq. The SWEEP annunciator is now on and a continuous sweep will begin. During the sweep, the progress bar becomes active on the display, indicating the status of the current sweep.

11.Watch the display and ensure that the Unlevel annunciator does not appear at any time during a full sweep.

The Unlevel annunciator may turn on and off, or remain on; both conditions indicate a failure. If this occurs, refer to “Maximum Leveled Power Check Failure” on page 22 for further instructions.

12.Press Sweep > Off.

13.Repeat steps 5-12for each frequency range, specific to your model number and options.

Maximum Leveled Power Check Failure

If a maximum leveled power check fails, perform the following procedure:

1.Verify the limits for that particular option using the data sheet.

2.If the Unlocked annunciator is displayed, refer to the troubleshooting section of the Service Guide.
