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
setto10.Theinstrument
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
valueof*ESEtochoose
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.
