Enter The Measurement Parameters; Perform A Normalization Calibration - HP 8712ET User Manual

NOTE
Making Measurements
Measuring Conversion Loss
Inserting a 700 MHz bandpass filter in the measurement setup removes
the unwanted signals at 200 MHz, 900 MHz, and 1100 MHz, providing
an accurate measurement of the desired IF signal at 700 MHz.
In the following example, the conversion loss of a mixer will be measured
with RF input frequencies over a 15 MHz span centered at 900 MHz.
With an LO frequency of 200 MHz, the mixer IF frequency will sweep
over a 15 MHz span centered at 700 MHz.

This example measurement uses the default instrument parameters for
a conversion loss measurement. If your particular conversion loss
measurement requires different parameters (such as source power level,
number of data points, and sweeptime), enter them now.

Perform a Normalization Calibration

Normalization is the simplest type of calibration. The analyzer stores a
measurement trace into memory and divides subsequent measurements
by the stored data to remove unwanted frequency-response errors. This
calibration is used for this measurement to remove the insertion loss
errors of the IF filter and the interconnect cables. Changing the
frequency span or number of measurement points will invalidate a
normalization calibration.
Perform the following steps to perform a normalization calibration:
