:SENSe<ch>[:POWer]:APERture:TIMe <ApTime>
Defines the aperture time (size of the acquisition interval) for the corresponding sensor.
Parameters:
<ApTime> float
Range: depends on connected power sensor
Increment: 1E-9
*RST: depends on connected power sensor
Example:
SENS:POW:APER:TIM 23ms
sets 23 ms aperture time.
Manual operation: See "Aperture Time" on page 155
:INITiate<ch>[:POWer]:CONTinuous
<Continuous>
The command switches the local state of the continuous power measurement by the
R&S NRP-Zxx power sensors on and off. Switching the local state off enhances the
measurement performance during remote control
The remote measurement is triggered by the READ query (command :READ<ch>[:
POWer]? on page 269) which also provides the measurement results. The local state
is not influenced by this command, measurements results can be retrieved with local
state on or off.
Parameters:
<Continuous> 0 | 1 | OFF | ON
*RST: OFF
Example:
INIT:CONT ON
switches local state of continuous power measurement on.
Manual operation: See " State " on page 150
:READ<ch>[:POWer]?
The command triggers the measurement with power sensors and provides the power
measurement result of the selected power sensor. The value is provided with the unit
set with command SENSe:UNIT[:POWer].
For certain power sensors, e.g. R&S NRP-Z81, two values are returned, first the value
for the average level and - separated by a comma - the peak level
Note: The local state is not influenced by this command, measurements results can be
retrieved with local state on or off. For long measurement times it is recommended to
use a SRQ (MAV bit) for command synchronization.
