Measurement Operations & Settings
Command:
:SENSe[n]:POWer:RANGe
Syntax:
:SENSe[n]:POWer:RANGe<wsp><value>[DBM]
Description:
Sets the power range for the channel.
The range changes at 10 dBm intervals. The corresponding ranges for linear
measurements (measurements in Watts) is given below:
Range
+10 dBm
0 dBm
-10 dBm
-20 dBm
-30 dBm
Upper Linear Power Limit
19.999 mW
1.9999 mW
199.99 uW
19.999 uW
1.9999 uW
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
Example:
:sens1:pow:rang -20DBM
Affects
All power meters
Command:
:SENSe[n]:POWer:RANGe?
Syntax:
:SENSe[n]:POWer:RANGe?
Description:
Returns the range setting for the channel.
Parameters:
None
Response:
The range setting as a float value in dBm (-30 to +10).
Example:
:sens1:pow:rang?
→
-2.00001
Affects
All power meters
Command:
:SENSe[n]:POWer:REFerence
Syntax:
:SENSe[n]:[CHANnel[m]]:POWer:REFerence<wsp>TOMODule|TOREF,<value>PW|NW|UW|MW|Watt|DBM|DB|MDB
Description:
Sets the channels reference value.
