8.2 Performing a Gain Calibration
Gain calibration (also called Thru calibration) is used to remove the gain and phase error introduced
by the connections between the measurement instrument and the DUT in a gain or transmission
measurement.
To achieve maximum accuracy,
do not change
the attenuators
after
having performed an
external calibration.
Hint:
Thru calibration can also be used in impedance measurements that are based on a
gain measurement. These measurement modes are e.g. Shunt-Thru, Series-Thru or Voltage/
Current. When performing a Thru calibration in such a mode, the underlying gain
measurement is calibrated and afterwards the calibrated gain result is transformed to
impedance.
Performing the calibration
In order to calibrate a gain measurement, please proceed as follows:
1. Build up the calibration setup. For details on the calibration setup, please see
Transmission (S21) measurement
8.2.2 Calibrating a Gain/Phase
2. In the
Bode Analyzer Suite
, click on the Gain calibration icon (either User-Range or Full-Range).
To learn more about the difference between User-Range and Full-Range calibration please check
8.3.1 Difference between Full-Range and User-Range calibration
3. The calibration dialog opens and the calibration state shows
Not Performed
.
4. Ensure that the calibration setup is connected properly and press
Start
.
5. Wait until the calibration has completed and the calibration state shows
Performed
.
6. Close the calibration dialog.
