4530 Series RF Power Meter
Remote Operation
MEASure:VOLTage
Description:
Return average voltage using a default instrument configuration.
Syntax:
MEASure[1|2]:VOLTage?
Returns:
Average voltage in linear volts
Valid Modes:
Automatically sets to Modulated or CW voltage mode before measurement.
4.5.2 INITiate and ABORt Commands
The purpose of the INITiate group of commands is to start and control the process of data acquisition once a
measurement has been configured. Depending on settings, the power meter may be commanded to begin either a
single measurement
(INITiate:CONTinuous OFF
) which stops when complete, or enter a “free-run” mode where data
acquisition occurs continuously (
INITiate:CONTinuous ON
). The
ABORt
command terminates any operation in
progress and prepares the instrument for an INITiate command. In some operating modes, the INITiate commands do
not actually start measurements, but rather arm a hardware trigger, which is then used to gate the actual measurements
cycle.
INITiate:CONTinuous
Description:
Set or return the data acquisition mode for single or free-run measurements. If
INITiate:CONTinuous
is set to ON, the 4530 immediately begins taking measurements
(Modulated, CW and Statistical modes), or arms its trigger and takes a measurement each
time a trigger occurs (Pulse mode). If set to OFF, the measurement will begin (or be armed)
as soon as the INITiate command is issued, and will stop once the measurement criteria
(averaging, filtering or sample count) has been satisfied. Note that
INITiate:IMMediate
and
READ
commands are only valid when
INITiate:CONTinuous
is set to OFF.
Syntax
:
INITiate:CONTinuous
Argument:
Valid Modes:
Any
INITiate:IMMediate
Description:
Starts a single measurement cycle when
INITiate:CONTinuous
is set to OFF. In CW or
Modulated mode, the measurement will complete once the power has been integrated for
the full FILTer time. In Pulse mode, enough trace sweeps must be triggered to satisfy the
AVERaging setting. In Statistical mode, acquisition stops once the sample count reaches
the preset terminal count. In each case, no reading will be returned until the measurement
is complete. This command is not valid when
INITiate:CONTinuous
is ON.
Syntax:
INITiate[:IMMediate[:ALL]]
Argument:
None
Valid Modes:
Any
Restrictions:
INITiate:CONTinuous
must be OFF
