Offsetting Limit Lines
The limit offset functions allow you to adjust the limit lines to the frequency and output level
of your device. For example, you could apply the stimulus offset feature for testing tunable
filters. Or, you could apply the amplitude offset feature for testing variable attenuators, or
ripple in filters with variable loss.
This example shows you the offset feature and the limit test failure indications that can appear
on the analyzer display.
1. To offset all of the segments in the table by a frequency, (for example, 50 MHz),
press:
The analyzer beeps and a FAIL notation appears on the analyzer display, as shown in
Figure 2-45.
