Cable and Antenna Analyzer Measurement Guide : Calibration : Calibration Verification
 
Calibration Verification
During the calibration process in Return Loss mode (Measurements > Return Loss), either with discrete calibration components or with the InstaCal module, there are typical measurement levels expected. Verifying the measurement levels displayed on the screen during calibration can save valuable time in the field.
Trace Characteristics in Return Loss Mode
As the individual calibration components are connected to the RF out port, the following measurement levels will be displayed on the screen:
When an OPEN is connected, a trace will be displayed between 0 dB to 10 dB.
When a SHORT is connected, a trace will be displayed between 0 dB to 10 dB.
When a LOAD is connected, a trace will be displayed between 0 dB to 50 dB.
