Response And Isolation Error Correction For Reflection Measurements - Agilent Technologies 8719ES User Manual

12.Return the averaging to the original state of the measurement. For example, reduce the
averaging factor by at least four times or turn averaging off.

You can connect and measure your device under test.
Response and Isolation Error Correction for Reflection
Measurements
The response and isolation error correction for reflection measurements provides the
following benefits:
• removes frequency response of the test setup
• removes isolation in transmission measurements
• removes directivity in reflection measurements
To perform the response and isolation error correction for reflection measurements:
1. Press .

2. Select the type of measurement you want to make.
If you want to make a reflection measurement on PORT 1 (in the forward direction,
S ), leave the instrument default setting.
