Item Description/Default Range of values
expected_value
(for the expected power 
level)
A numeric value for the expected power level. The units of 
measurement are dBm and W. The default units are defined 
by UNIT:POWer. 
sensor-dependent
DEF
[a]
resolution A numeric value for the resolution. If unspecified, the current 
resolution setting is used.
1 to 4
[b]
1.0, 0.1, 0.01, 0.001
DEF
[a]
source list The measurement channel which the command is 
implemented on. The U8480 Series supports only one 
channel. Therefore, the only valid value is (@1). 
(@1)
[a] The mnemonic DEF means DEFault. This is not equivalent to the DEFault parameter used in the command subsystems. The parameters must 
be entered in the specified order. If parameters are omitted, they default from the right. The parameter DEFault is used as a placeholder. 
Specifying DEF leaves the parameter value unchanged.
[b] When the measurement result is linear, this parameter represents the number of significant digits. When the measurement result is 
logarithmic, 1 to 4 represents 1, 0.1, 0.01, and 0.001 respectively.
