Measurement Operations & Settings
example:
sens1:pow:atim 1s
affects:
All power meters and return loss modules
dual sensors:
Can only be sent to master channel, slave channel is also affected.
command:
:SENSe[
n
]:[CHANnel[
m
]]:POWer:ATIMe?
syntax:
:SENSe[
n
]:[CHANnel[
m
]]:POWer:ATIMe?
description:
Returns the averaging time for the module.
parameters:
none
response:
The averaging time as a
float
value in seconds.
example:
sens1:pow:atim?
->
+1.00000<END>
affects:
All power meters and return loss modules
dual sensors:
Can only be sent to master channel, slave channel parameters are identical.
command:
:SENSe[
n
]:[CHANnel[
m
]]:POWer:RANGe[:UPPer]
syntax:
:SENSe[
n
]:[CHANnel[
m
]]:POWer:RANGe[:UPPer]<wsp><value>[DBM]
description:
Sets the power range for the module. For a return loss module, sets the power range of the return loss diode.
The range changes at 10 dBm intervals. The corresponding ranges for linear measurements (measurements in Watts) is
given below:

parameters:
The range as a
float
value in dBm. The number is rounded to the closest multiple of 10, because the range changes at
10 dBm intervals. Units are in dBm.
response:
none
