Troubleshooting
If You Encounter a Problem
• Can’t Turn Off Sweep Mode?
In the sweep mode menu you can choose to set the sweep to various sweep types
or to turn sweep off. Press
Sweep/List, Sweep and choose Off from the sweep
mode selections.
• Recalled a Register and Sweep List is Missing?
Sweep information is not stored as part of the instrument state in a storage
register. Only the current step and list sweep is available to the signal generator
and it cannot be stored nor will it survive a factory preset.
• All of the Registers Where You Previously Stored Instrument
States are Empty?
The save/recall registers are backed-up by a battery when AC power to the signal
generator is not connected. The battery may need to be replaced. To verify that the
battery has failed, turn power off line power to the signal generator and unplug it.
Then plug in the instrument and cycle power on. If either error message
−311 or
−700 is stored in the error message queue, your battery has failed. Refer to the
service guide for battery replacement instructions.
• Saved an Instrument State in a Register but the Register is
Empty or Contains the Wrong State?
If you have intentionally, or unintentionally, selected a register number that is
greater than 99, the signal generator will automatically select register 99 to save
your instrument state. If the register number you intended to use is empty or
contains the wrong instrument state, recall register 99 as the instrument state may
be saved there.
• The Power Supply has Shut Down
If the power supply is not working, it requires repair or replacement. There is no
user-replaceable power supply fuse. Refer to the service guide for instructions.
