Anritsu S113C, S332C, S114C Calibration Verification, Trace Characteristics in Return Loss Mode

Chapter 3 Getting Started

Calibration Verification

During the calibration process in Return Loss mode, either with discrete calibration compo- nents 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 discrete calibration components are connected to the Site Master RF out port, the following measurement levels will be displayed on the screen:

￿When an OPEN is connected, a trace will be displayed between 0-10 dB.

￿When a SHORT is connected, a trace will be displayed between 0-10 dB.

￿When a LOAD is connected, a trace will be displayed between 0-50 dB.

When an InstaCal module is connected to the Site Master RF out port, the following mea- surement levels will be displayed on the screen:

￿When the Site Master is measuring an equivalent OPEN, a trace will be displayed between 0-20 dB.

￿When the Site Master is measuring an equivalent SHORT, a trace will be displayed between 0-20 dB.

￿When the Site Master is measuring an equivalent LOAD, a trace will be displayed between 0-50 dB.

The following procedures explain Manual and InstaCal calibration methods. Refer to Figure 3-2 for a calibration setup diagram.
