Frequency-Offset Measurement (Option 008)
Measurement of Mixers
Step 3. Use the X-Axis key to set the frequency data.
NOTE When Frequency Offset is OFF, and LO Frequency is ON (mixer measurement by
vector-mixer calibration),
Normal, RF+LO, RF-LO and LO-RF are enabled. When
Frequency Offset is ON, Base, Stimulus and Response are enabled. You can change the
frequency data for each trace.
NOTE If you use the LO-RF setting, you can display information in the same way as with the
mixer measurement function of the Agilent PNA series by changing the measurement data
according to the steps below.
Step 1. Press (or ) and (or ) to activate the trace for
which you want to change the measurement data.
Step 2. Press -
Frequency Offset to display the “Frequency Offset Menu.”
Step 3. Use the
X-Axis key to change the frequency data.
Step 4. Use the
LO-RF key to change the frequency data to IF frequency.
Step 5. Convert the measurement data to a complex conjugate number.
Step 6. Press the
Conversion key to display the “Conversion Menu.”
Step 7. Press
Function to select Conjugation.
Step 8. Press Conversion to turn it ON.
NOTE The basic frequency is a frequency range set by the and keys in the
STIMULUS bloc.
NOTE If you change the frequency data, it will affect all of the measurement values, such as the
marker’s read value, conversion parameter, and conversion into time domain.
