BAD NORM A normalization error will occur if the current
ERR 902
spectrum analyzer state is not the same as the state
stored by the last execution of the STORETHRU or
STORESHORT command.
This will happen when several open/short or thru
calibrations are performed. The NORMLIZE function
recalls the last calibration run. If one of the earlier
SHORT or THRU states has been recalled just before
turning the NORMLIZE function on, then the current
and recalled states don't match and the error occurs. To
avoid this error, update the STORETHRU or
STORESHORT state register with the current state
before turning NORMLIZE on. The STORETHRU state
register is state register 9. The STORESHORT state
register is state register 8. It is a good idea to take a
sweep (TS command) prior to saving the state using the
SAVES 8 or SAVES 9 command.
A > DLMT Unnormalized trace A is off screen with trace
ERR 903
math or normalization on.
B > DLMT Calibration trace (trace B) is off screen with
ERR 904
trace math or normalization on.
EXT REF Unable to lock cal oscillator when set to external
ERR 905
reference. Check that external reference is within
tolerance.
OVENCOLD The oven controlled crystal oscillator (OCXO)
ERR 906
oven is cold.
DO IFCAL Unit is still performing IF calibration, or is in
ERR 907
need of IF calibration which were not done due to an
OVENCOLD condition.
BW>>SPCG Channel bandwidth is too wide, compared to
ERR 908
the channel spacing, for a meaningful computation.
SPAN<ACP The frequency span is too small to obtain a
ERR 909
valid ACP measurement.
SPAN>ACP The frequency span is too wide, compared to
ERR 910
the channel bandwidth, to obtain a valid ACP
measurement.
ACP STATE The adjacent channel power measurement
ERR 911
has been compromised (invalid measurement
parameters).
SP <CHBW The channel spacing is too narrow, compared
ERR 919
to the channel bandwidth, to obtain a valid channel
power bandwidth measurement.
