Keysight U8480 Series - Table 1-2 Settling Time for Normal Speed, ×2 Speed, and Fast Speed 44 Table 1-3 Range of Values for Measurement Limits

U8480 Series Remote Operation 1
U8480 Series Programming Guide 47
Table 1-3 Range of values for measurement limits
An example of the programming sequence is shown as follows.
Checking for limit failures
To check for limit failures, use the CALCulate[1]:LIMit:FAIL? and/or
CALCulate[1]:LIMit:FCOunt? queries.
The CALCulate[1]:LIMit:FAIL? query will return 1 if one or more limit failures
have occurred. If no limit failures have occurred, 0 will be returned.
The CALCulate[1]:LIMit:FCOunt? query will return the total number of limit
failures.
Unit Maximum Minimum Default maximum Default minimum
dBm 230 dBm
–150 dBm
90 dBm
–90 dBm
W 1e20 W 1e–18 W 1e6 W 1e–12 W
-> SYST:PRES DEF // Presets the U8480 Series.
-> UNIT:POW DBM // Sets the measurement unit to dBm.
-> CALC:LIM:STAT 1 // Enables the test limit feature.
-> CALC:LIM:LOW 4 // Sets the lower limit to 4 dBm.
-> CALC:LIM:UPP 10 // Sets the upper limit to 10 dBm.
The U8480 Series will start to monitor the RF power between 4 dBm (lower limit)
and 10 dBm (upper limit). RF power that is either <4 dBm or
>10 dBm will cause the U8480 Series to log an error.
