Power Sensor Remote Operation 1
U2000 Series Programming Guide 29
Setting Limits (Check Header - same as previous)
The power sensor can be configured to verify the current measurement in any
measurement line against predefined upper and/or lower limit values. The
range of values that can be set for the upper and lower limits and the default
values depends on the measurement units in the currently measurement line -
see Table 1- 2.
Tab le 1-2 Range of Values for Measurement Limits
Checking for Limit Failures
There is a way to check for limit failures:
• Use the CALCulate[1]:LIMit:FAIL? and CALCulate[1]:LIMit:FCOunt?
commands for measurement limits
Using CALCulate
Using CALCulate to check the measurement limit failures in Figure 1- 4
would return the following results:
Window
Units
Default
Maximum Minimum Maximum Minimum
dB +200 dB
–180 dB
60 dB
–120 dB
dBm +230 dBm
–150 dBm
90 dBm
–90 dBm
% 999.9 X% 100.0 a% 100.0 M% 100.0 p%
W 100.000 XW 1.000 aW 1.000 MW 1.000 pW
CALCulate[1]:LIMit:FAIL? Returns 1 if there has been 1 or
more limit failures or 0 if there
have been no limit failures. In this
case 1 is returned.
CALCulate[1]:LIMit:FCOunt? Returns the total number of limit
failures, in this case 2.
