Description
Reserved: This bit is not used by the analyzer, but is for
future use with other Agilent products.
No Result Available: A 1 in this bit position
indicates that a measurement terminated with no
measurement results.
Measurement Timeout: A 1 in this bit position
indicates that a measurement terminated due to a timeout.
Data Uncalibrated Summary: This is the summary
bit for the Questionable Status Integrity Uncalibrated
Register.
IF/ADC Over Range: The signal input level is too high,
causing the analyzer analog-to-digital converter (ADC)
range to be exceeded. This may occur with resolution
bandwidths less than or equal to 300 Hz in zero span.
Over Range: A 1 in this bit position indicates that the
signal is too large at the analog-to-digital converter (ADC).
Under Range: A 1 in this bit position indicates that the
signal is too small at the analog-to-digital converter (ADC).
Insufficient Data: A 1 in this bit position indicates
that there is not enough information to perform the
measurement or function.
Acquisition Failure: A 1 in this bit position
indicates that the demod algorithm cannot correlate to the
signal.
Memory Problem: A 1 in this bit position indicates a
failure of the file system memory or digital signal processor
(DSP) memory.
Auto-Trigger Timeout: A 1 in this bit position
indicates that the measurement timed out due to no trigger.
Trigger Problem: A 1 in this bit position indicates that
the measurement timed out due to no trigger.
Invalid Data: A 1 in this bit position indicates that the
present trace data does not reflect the existing analyzer
state. Trigger a new sweep and/or measurement.
Unidentified Error: A 1 in this bit position indicates
that a measurement has terminated for a reason other than
that given in any of the other bits.
