Troubleshooting

Cannot Turn Off Help Mode

Cannot Turn Off Help Mode

1.Press Utility > Instrument Info/Help Mode

2.Press Help Mode Single Cont until Single is highlighted.

The signal generator has two help modes; single and continuous.

When you press Help in single mode (the factory preset condition), help text is provided for the next key you press. Pressing another key will exit the help mode and activate the key’s function.

When you press Help in continuous mode, help text is provided for the next key you press and that key’s function is also activated (except for Preset). You will stay in help mode until you press Help again or change to single mode.

Signal Generator Locks Up

If the signal generator is locked up, check the following:

Make sure that the signal generator is not in remote mode (in remote mode, the R annunciator appears on the display). To exit remote mode and unlock the front panel keypad, press Local.

Make sure that the signal generator is not in local lockout condition. Local lockout prevents front panel operation. For more information on local lockout, refer to the E8257D/67D PSG Signal Generators Programming Guide.

Check for a progress bar on the signal generator display, which indicates that an operation is in progress.

Press Preset.

Cycle power on the signal generator.

Fail-Safe Recovery Sequence

Use the fail- safe recovery sequence only if the previous suggestions do not resolve the problem.

CAUTION This process does reset the signal generator, but it also destroys the following types of data:

all user files (instrument state and data files)

DCFM/DCΦM calibration data

persistent states

NOTE Do not attempt to perform any other front panel or remote operations during the fail- safe sequence.

To run the fail- safe sequence, follow these steps:

1.Hold down the Preset key while cycling power.

2.Continue to hold down the Preset key until the following message is displayed:

WARNING You are entering the diagnostics menu which can cause unpredictable instrument behavior. Are you sure you want to continue?
