User-Generated Errors (900 to 999)

These error codes indicate user-generated errors.
900 TG UNLVL Tracking generator output is unleveled.
901 TGFrqLmt Tracking generator output unleveled because START
FREQ is set below tracking generator frequency limit
(300 kHz).
902 BAD NORM The state of the stored trace does not match the
current state of the spectrum analyzer.
903 A > DLMT Unnormalized trace A is off-screen with trace math or
normalization on.
904 B > DLMT Calibration trace (trace B) is off-screen with trace
math or normalization on.
905 EXT REF Unable to lock cal oscillator when set to external
frequency reference. Check that the external 10 MHz
reference is within tolerance.
906 OVENCOLD The oven-controlled crystal oscillator (OCXO) oven is
cold.
907 DO IF CAL Unit is still performing IF calibrations, or is in need
of IF calibrations which were not yet done due to an
OVENCOLD condition. An OVENCOLD error is
indicative of a bandwidth ≤1 kHz not getting calibrated.
908 BW>>SPCG Channel bandwidth is too wide, compared to the
channel spacing, for a meaningful adjacent channel
power computation.
909 SPANACP The frequency span is too small to obtain a valid
adjacent channel power (ACP) measurement.
910 SPAN>ACP The frequency span is too wide, compared to the
channel bandwidth, to obtain a valid adjacent channel
power (ACP) measurement.
911 ACPSTATE Adjacent channel power (ACP) measurement has been
compromised (invalid measurement parameters).
921 ↑AMPCOR↑ Measurement data which would normally be displayed
above the top graticule, and therefore has unspecified
accuracy, has been corrected by the amplitude
correction function (ampcor) to appear between the top
and bottom graticule.
922 ↓AMPCOR↓ Measurement data which would normally be displayed
below the bottom graticule, and therefore has
unspecified accuracy, has been corrected by the
amplitude correction function (ampcor) to appear
between the top and bottom graticule.
