Measurement function Output unit
:SWR O
:RLOS DB
:REFL O
The UNIT commands affect the parameters of the following commands:
CALC:LIMit:UPPer, CALC:
LIMit:LOWer, CALC:RELative, DISP:METer:UPPer
and DISP:METer:LOWer.
A.4.1.6 Division of MEAS?
MEAS? can be divided into other high-level measurement commands.
MEAS?
⇔
CONF [<parameters list>]
READ? [<parameters
list>]
The CONF command configures the measurement, whereas READ? starts the measure-
ment, and calculates and provides the result.
This division offers two advantages:
●
The measurement has to be configured only once and several measurements (with
several READ? commands) can be performed in succession. This means better
performance as compared to measurements performed with MEAS?, since the time
for configuring the measurement is only used once.
●
After CONF, settings can be adapted to user's requirements by means of low-level
commands (see below).
If a list of parameters is indicated for the READ command, it must correspond to the list
for the preceding CONF command.
After a measurement has been completed, i.e. the data from the sensors is available, it
is sometimes interesting to evaluate this data several times without starting a new
measurement each time. Since this is not possible with the above commands, the
READ? command can be replaced by the INIT and FETCh? commands.
READ?
⇔
INIT
FETCh?
[<list
of parameters>]
FETCh? evaluates existing data if the data is valid. FETCh?
may select another calcu-
lation function if the measurement can be evaluated with the available measured data.
