Error Messages
CAUTION
Exposing the analyzer to high levels of input power over a prolonged
time period can damage the circuitry.
When operating remotely, the status bit should be monitored for this
condition to avoid incorrect measurement results.
PARAMETER ERROR: _ _ _
The specified parameter is not
recognized by the spectrum analyzer. See the appropriate
programming command description to determine the correct
parameters. (U)
Password required
Indicates that the service function cannot be
accessed without the password. (U)
Power-up selftest failed Boot ROM checksum:
Indicates a
test of the bootrom produced a checksum error. (H)
Power-up selftest failed RAM error:
Indicates a test of
RAM produced an error. (H)
Power-up selftest failed Checksum:
Indicates a test of the
instrument ROM produced a checksum error. (H)
Require 1 signal > PEAK EXCURSION above PEAK
THRESHOLD
Indicates that the N dB PTS routine cannot locate a
signal that is high enough to measure. The signal must be greater
than the peak excursion above the threshold level to measure. (U)
Require 3 signals > PEAK EXCURSION above PEAK
THRESHOLD
Indicates that the % AM routine cannot locate three
signals that are high enough to measure. The signals must be
greater than the peak excursion above the threshold level to
measure. (U)
Require 4 signals > PEAK EXCURSION above PEAK
THRESHOLD
Indicates that the TOI routine cannot locate four signals
that are high enough to measure. The signals must be greater than
the peak excursion above the threshold level to measure. (U)
Required Option Not Installed
Indicates that the function
selected requires optional hardware that is not currently available.
(U)
RF LO Unlocked
Indicates that the local oscillator within the
instrument’s RF assembly is unlocked. (H)
