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.

Figure 2-63 Limits checking applications

In this application a swept frequency signal is applied to the input of the
Device Under Test. The power meter measures the output power. The
limits have been set at +4 dBm and +10 dBm. A fail occurs each time the
output power is outside these limits as shown in
