Figure 2-11: Limits Checking Application
Figure 2-12: 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 2-12.
Setting Window Limits
The power meter can be configured to verify the current measurement in
either window against predefined upper and/or lower limit values. The
range of values that can be set for the upper and lower limits and the
