Calibrating for Increased Measurement Accuracy
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
1. Press .
2. Select the type of measurement you want to make.
❏ If you want to make measurements in the forward direction (S
21
S
11
), press:
or on ET models:
❏ For ES analyzers, if you want to make measurements in the reverse direction (S
12
S
22
), press:
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 softkey,
press:
(select your type of kit)
If your type of calibration kit is not listed in the displayed menu, refer to "Modifying
Calibration Kits" on page 7-56.
6. To select the correction type, press
and select the correction type.
❏ If you want to make measurements in the forward direction, press:
or on ET models:
❏ For ES analyzers, if you want to make measurements in the reverse direction, press:
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.
