Setting Measurement Limits

You can configure the power meter to detect when a measurement has crossed
over a predefined upper and/or lower limit value.
Limits are boundaries set for a certain power range and it can be applied to
power, ratio or difference measurement.

set at +4 dBm and +10 dBm. A fail occurs each time the output power is outside
these limits as shown in
