Enhanced Frequency Response Error Correction

Enhanced Frequency Response Error Correction
The enhanced frequency response error correction removes the following errors in the
forward direction in ET models or in both the forward and reverse directions in ES models:
• removes directivity errors of the test setup
• removes source match errors of the test setup
• removes isolation errors of the test setup (optional)
• removes frequency response of the test setup

3. Set any measurement parameters that you want for the device measurement: power,
format, number of points, or IF bandwidth.
4. To access the measurement correction menus, press:
5. If your calibration kit is different than the kit specified under the
press:
CAL KIT SELECT CAL KIT
If your type of calibration kit is not listed in the displayed menu, refer to

6. To select the correction type, press
and select the correction type.
If you want to make measurements in the forward direction, press:
S11/S21 ENH. RESP.
For ES analyzers, if you want to make measurements in the reverse direction, press:
S22/S12 ENH. RESP.
7. Connect a shielded open circuit to PORT 1 (or PORT 2 for reverse measurements).
NOTE Include any adapters that you will have in the device measurement. That is,
connect the standard to the particular connector where you will connect your
device under test.
