Setting Measurement Limits

You can configure the N432A to detect when a measurement is outside of a
predefined upper and/or lower limit value.
Limits are boundaries set for a certain power range and can be applied to the
power, ratio, or difference measurement.
The N432A can be configured to verify the power being measured against an
upper and/or lower limit value. The range of values that can be set for lower and
upper limits is –150.00 dBm to +230.00 dBm. The default upper limit is
+90.00 dBm and the default lower limit is –90.00 dBm.
The range of values that can be set for the upper and lower limits and the default
values depend on the measurement units in the currently selected measurement
line, as listed in the following table:

To enter a value for the upper test limit or query the current upper limit setting for
the specified window/measurement, use the
CALCulate[1]|2|3|4:LIMit:UPPer[:DATA] <numeric_value> command
and CALCulate[1]|2|3|4:LIMit:UPPer[:DATA]? [MIN|MAX] query
respectively.
To enter a value for the lower test limit or query the current lower limit setting for
the specified window/measurement, use the
CALCulate[1]|2|3|4:LIMit:LOWer[:DATA] <numeric_value> command
and CALCulate[1]|2|3|4:LIMit:LOWer[:DATA]? [MIN|MAX] query
respectively.
