Programming Fundamentals
Across PSA Modes: Specific Command Differences
Some programming commands operate differently depending on which
Mode the analyzer is set to.
Command
Spectrum Analysis, Phase Noise
and Noise Figure Mode
Basic, cdmaOne, cdma2000,
1xEV-DO, W-CDMA, GSM, EDGE,
NADC, PDC Modes
CONFigure:
<measurement>
Accesses the measurement and sets
the instrument settings to the
defaults. Averaging is turned on and
set to 10. The instrument is put in
single measurement mode. It does
not initiate a measurement. Use
INIT:IMM to make one
measurement.
Accesses the measurement and sets
the instrument settings to the
defaults. If you were already in
single measurement mode, it takes
one measurement and then waits. If
you were in continuous measurement
mode it continues to measure.
*ESE default Default is 255 which means that
every error/status bit change that has
occurred will be returned with a
*ESR? query. You must set the value
of *ESE to choose only the bits/status
that you want returned.
Default is 0 which means that none
of the error/status bit changes that
have occurred will be returned with a
*ESR? query. You must set the value
of *ESE to choose the bits/status that
you want returned.
TRIGger
commands
For these modes, only one trigger
source can be selected and it will be
common across the modes. Also, only
one value can be set for the trigger
delay, level, or polarity.
For these modes, a unique trigger
source can be selected for each mode.
Also, each trigger source can have
unique settings for the its delay,
level, and polarity.
Saving and
recalling traces
Traces can only be saved when in the Spectrum Analysis mode
(MMEM:STOR:TRAC). This is because the instrument state must be saved
along with the trace data and the state data varies depending on the number
of modes currently available in the instrument.
