Frequency Response And Isolation Error Corrections; Response And Isolation Error Correction For Transmission Measurements - Agilent Technologies 8719ES User Manual

Frequency Response and Isolation Error Corrections

You can make a response and isolation correction for the following measurements:
• reflection measurements
• transmission measurements
• combined reflection and transmission measurements
Although you can perform a response and isolation correction for reflection
NOTE
measurements, we recommend that you perform an S
correction; it is more accurate and just as convenient.
Response and Isolation Error Correction for Transmission
Measurements
This procedure is intended for measurements that have a measurement range of greater
than 90 dB.
1. Press .
Preset
2. Select the type of measurement you want to make.
If you want to make a transmission measurement in the forward direction (S
press:
Trans: FWD S21 (B/R)
Meas
For ES analyzers, if you want to make a transmission measurement in the reverse
direction (S ), press:

3. Set any other measurement parameters that you want for the device measurement:
power, number of points, IF bandwidth.
4. To access the measurement correction menus, press:
