Enhanced Frequency Response Error Correction
17.Press and select from the following two options:
❏ If you will be measuring devices with a dynamic range less than 90 dB, press
.
❏ If you will be measuring devices with a dynamic range greater than 90 dB, follow
these steps:
a. Connect impedance-matched loads to the test ports. Include the adapters that you
would include for your device measurement.
NOTE If you will be measuring highly reflective devices such as filters, use the test
device, connected to the reference plane and terminated with a load, for the
isolation standard.
b. Activate at least four times more averages than desired during the device
measurement.
c. Press
.
d. Return the averaging to the original state of the measurement, and press
.
18.To compute the error coefficients, press .
The analyzer displays the corrected measurement trace. The analyzer also shows the
notation Cor at the left of the screen, indicating that error correction is on.
Enhanced Reflection Calibration
19.If you are measuring a bilateral device and want to remove the load match error,
activate the enhanced reflection calibration by pressing and
then pressing until ON is selected.
NOTE You can save or store the measurement correction to use for later
measurements. Refer to Chapter 4, “Printing, Plotting, and Saving
Measurement Results” for procedures.
20.This completes the enhanced response correction procedure. You can connect and
measure your device under test.
