Calibrating for Increased Measurement Accuracy
Calibrating Using Electronic Calibration (ECal)
NOTE When returning to the Confidence Check menu from the ECal Service menu, press the
softkey on the ECal Confidence Check menu. If this softkey is
not pressed, the confidence check information displayed may not be accurate.
Toggles the analyzer to show the data for the following S-parameters:
• S11 (ES models)
• S21 (ES models)
• S12 (ES models)
• S22 (ES models)
• RFL (ET models) - Reflection
• TRN (ET models) - Transmission
Toggles through the following trace types:
• DATA&MEM displays two traces representing the measured ECal results and the
module's premeasured calibration data trace.
• DATA/MEM displays a single trace representing a ratio of the measured ECal
results to the module's premeasured calibration data.
• DATA-MEM displays a single trace representing the difference between the
measured ECal results and the module's premeasured calibration data.
• DATA displays a single trace representing only the measured ECal results.
• MEM displays a single trace representing only the module's premeasured
calibration data.
Changes scale and reference values to bring the trace data in view on the display.
The analyzer determines the smallest possible scale factor that will put all displayed
data onto 80% of the vertical graticule. The reference value is chosen to put the trace
in center screen.
Returns to the ECal Confidence Check menu.
