Calibrating for Increased Measurement Accuracy
Calibrating Using Electronic Calibration (ECal)
Perform the Confidence Check
The confidence check is a means of visually checking the quality of the calibration. The confidence check
displays the currently measured data (DATA trace) and the factory-premeasured data (MEM trace) for the
module's confidence state. The confidence state, an independent reference standard, was not used for the
calibration. For a good calibration measurement, there should be no significant difference between the
traces (see
Figure
6-24).
To Perform the Confidence Check
NOTE
A confidence check is only valid after an ECal has been performed.

display the S-parameter calibration data for which you calibrated. Uncalibrated S-parameter data traces
are invalid. The memory trace still displays the module's factory-premeasured trace.
For example,
If you performed:
A 1-port calibration
•
S11 1-PORT
(ES models)
•
S22 1-PORT
(ES models)
•
REFLECTION 1-PORT
An enhanced response calibration
•
S11/S21 ENH. RESP.
•
S22/S12 ENH. RESP.
•
TRANS/REFL ENH. RESP.
