Warning/Status

Description

Message

This warning message indicates that the 100 MHz

OVN COLD

Crystal oven (or the 10 MHz Crystal oven if Option 16 is

installed) has not reached operating temperature.

Normally displayed during a cold start of the signal

generator. If the message is displayed during normal

operation, it could indicate a malfunction. Run self-test

to verify.

Displayed when the RF output goes unleveled. Normally

UNLEVELED

caused by exceeding the specified leveled-power rating.

Reducing the power level usually clears the warning

message.

If the warning message is displayed only when AM is

selected ON, the modulating signal may be driving the

RF output unleveled. Reducing the modulating signal or

adjusting the power level usually clears the warning.

When Unlocked/Narrow FM or Unlocked/Wide FM is

UNLOCKED

selected ON, this warning message appears indicating

that the instrument is not phase-locked during this FM

mode of operation.

This warning message is displayed when the AM Rate

Reduce Rate

or FM Rate is set >100 kHz for a non-sinewave

modulating waveform. Amplitude or frequency

modulation of the output signal will continue but the

modulating waveform may be distorted.

This status message indicates that an external 10 MHz

EXT REF

signal is being used as the reference signal for the

682XXB/683XXB.

This status message indicates that a constant (offset)

OFFSET

has been applied to the displayed power level.

This status message indicates that a power slope

SLOPE

correction has been applied to the ALC.

This status message indicates that a user level flatness

USER 1...5

correction power-offset table has been applied to the

ALC.

This status message indicates that the 682XXB/683XXB

SS MODE

has been placed in a source lock mode for operation

with a 360B Vector Network Analyzer.
