Status Peaking Signal (no corresponding status bit)
The instrument is executing a tracking generator peak.
Status Preferred resolution bandwidth not available.
The calculated required resolution bandwidth for this measurement is not
available.
Status (RF Align Failure) status bit only, no message
A failure has occurred during the alignment of the RF section.
Measurement results may be invalid.
Status Signal Ident On, Amptd Uncal (Signal Ident On)
Indicates that the amplitude measurement could be uncalibrated because
the signal identification feature is on.
Status Signal level is low.
Indicates the signal can be correlated, however the level is below that
specified to ensure accurate measurement results.
Status Source LO Unlevel (Source LO Unleveled)
The internal circuitry of the local oscillator (LO) in the tracking generator
has become unleveled. This condition must be corrected to make valid
measurements.
Status Source LO Unlock (Source Synth Unlocked)
The phase-locked circuitry of the local oscillator (LO) in the tracking
generator has become unlocked. This condition must be corrected to make
valid measurements.
Status Source Unlevel (Source Unleveled)
Indicates the source power is set higher or lower than the analyzer can
provide, the frequency span extends beyond the specified frequency range
of the tracking generator, or the calibration data for the source is incorrect.
Status Start freq must be greater than fixed LO freq
The current measurement mode requires that the start frequency must be
greater than the fixed LO frequency.
Status Start freq must be greater than start RF freq
The current measurement mode requires that the start IF (output to DUT)
frequency must be greater than the start RF (input to DUT) frequency.
Status Start – LO freq must be >= min system input freq
The current measurement mode requires that the start RF (input to DUT)
frequency must be more than the minimum system input frequency away
from the fixed LO frequency.
