Calibrating for Increased Measurement Accuracy
Frequency Response Error Corrections
For ES analyzers, press . This sets the source at PORT 1.
4. Set any other measurement parameters that you want for the device measurement: power, number of
points, IF bandwidth.
5. To perform a receiver error correction, press:
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.
6. This completes the receiver calibration for transmission measurements. You can connect and measure
your device under test.
NOTE The accuracy of the receiver calibration will be nearly the same as the test port power
accuracy; and the test port power accuracy can be significantly improved by performing a
power meter source calibration, as described later in
"Power Meter Measurement
Calibration" on page 6-33.
Calibrations at powers other than 0 dBm are possible. Receiver calibration normalizes the trace to the value
set for the reference level. For example, to do a receiver calibration at 10
dBm, set the source to10 dBm,
set the reference level to 10 dBm, then perform the receiver calibration.
