Figure 2-7: Limits Checking Results
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 Figure 2-7.
Checking for Limit Failures
Limit failures are displayed in the appropriate field in the measurement
window on the power meter’s display as shown in Figure 2-8.
