Calibrating for Increased Measurement Accuracy
Frequency Response Error Corrections
Frequency Response Error Corrections You can remove the frequency response of the test setup for the following measurements:
• reflection measurements
• transmission measurements
• combined reflection and transmission measurements
Response 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,
S11), leave the instrument default setting.
❏For ES analyzers, if you want to make a reflection measurement on PORT 2 (in the
reverse direction, S22), press:
3. Set any other measurement parameters that you want for the device measurement:
power, sweep type, number of points, or IF bandwidth.
4. To access the measurement error-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 7-57.
6. To select a response correction, press:
Connect the short or open calibration standard to the port you selected for the test port
(PORT 1 for S11 or PORT 2 for S22 on ES analyzers).
NOTE Include any adapters or cables that you will have in the devic e meas ure ment.
That is, connect the standard device to the particular connector where you
will connect your DUT.
