HP 8753E manual Lksting a Device with Limit Lines, Setting Up the Measurement Parameters

lksting A Device with Limit Lines

Limit testing is a measurement technique that compares measurement data to constraints that you define. Depending on the results of this comparison, the analyzer will indicate if your device either passes or fails the test.

Limit testing is implemented by creating individual flat, sloping, and single point limit lines on the analyzer display. When combined, these lines can represent the performance parameters for your device under test. The limit lines created on each measurement channel are independent of each other.

This example measurement shows you how to test a bandpass filter using the following procedures:

ncreating flat limit lines

ncreating sloping limit lines

ncreating single point limit lines

nediting limit segments

nrunning a limit test

Setting Up the Measurement Parameters

1. Connect your test device as shown in Figure 2-40.

2.Press IpresetJ and choose the measurement settings. For this example the measurement settings are as follows:

You may also want to select settings for the number of data points, power, averaging, and IF bandwidth.

3. Substitute a thru for the device and perform a response calibration by pressing:
