●
Measurement results are assigned to a particular view. The commands used to define
the measurement statistics and to retrieve results are also view-specific, which makes
it possible to transfer a subset of results actually needed.
Example for context-specific commands
The following measurement control command affects the
EPSensor
measurement con-
text (external power sensor measurement) in the
GPRF:MEASurement
firmware appli-
cation:
INITiate:GPRF:MEASurement:EPSensor
The
EPSensor
measurement context appears as a fourth-level mnemonic. No view type
is specified.
Example for view-specific commands
The following command retrieves the results in the
EVMagnitude:DSSS
view (EVM for
DSSS signals) which is part of the
MEValuation
measurement context in the
WLAN:MEASurement<i>
firmware application:
FETCh:WLAN:MEASurement<i>:MEValuation:TRACe:EVMagnitude:DSSS:
CURRent?
The
EVMagnitude:DSSS
view is selected via the sixth- and seventh-level mnemonics.
READ...? and FETCh...? queries
The
READ...?
query is view-specific and calculates only the results needed for a par-
ticular view. This can result in a performance improvement compared to the context-
specific command sequence
INITiate...; FETCh...?
.
6.4 Control of the Instrument
The following sections describe the control of measurement, generator, and signaling
applications.
6.4.1 Generator Control
The commands used to control the different RF signal generators of the R&S CMW500
are analogous to the commands explained in section
. A generator
is in one of the following generator states:
●
OFF
: Generator turned off, resources either released or (partially) reserved from the
last time the generator was turned on.
●
PENDing
: Generator turned on, but still waiting for resource allocation, adjustment,
hardware switching. No output signal is available at the selected output connector.
●
ON
: Generator turned on, with all necessary adjustments finished. An output signal
is available at the selected output connector.
