CALCulate[1]|2|3|4:LIMit:FCOunt?
This query returns the total number of limit failures for the specified
window/measurement.
If the appropriate STATe commands are set to ON, each time a
measurement is initiated on the specified window/measurement and the
result is outside the limits, the counter is incremented by one.
If the measured value is equal to a limit, this is a limit pass.
The counter is reset to zero by any of the following commands:
• *RST
• CALCulate[1]|2|3|4:LIMit:CLEar:IMMediate
• CALCulate[1]|2|3|4:LIMit:CLEar:AUTO ON
When CALCulate[1]|2|3|4:LIMit:CLEar:AUTO is set to ON, the counter
is set to zero each time a measurement is:
• measured using MEASure?
•read using READ?
• initiated using:
• INITiate[:IMMediate] or,
• INITiate:CONTinuous ON
When CALCulate[1]|2|3|4:LIMit:CLEar:AUTO is set to ONCE, the
counter is set to zero the first time a measurement is:
• measured using MEASure?
•read using READ?
• initiated using:
• INITiate[:IMMediate] or,
• INITiate:CONTinuous ON
The maximum number of errors is 2
16
–1. If more than 2
16
–1 errors are
detected the counter returns to zero.
