Introduction
This chapter provides details and procedures for calibrating the Cable‑Antenna Analyzer modes of the Site Master S820E.
The Site Master is a high precision instrument. When making 1‑port or 2‑port measurements, the instrument must be calibrated in order to remove residual errors due to measurement setup conditions. Anritsu recommends performing the calibration under the same conditions as the measurement: temperature, frequency, number of points, source power, and IFBW. The calibration must be conducted using the appropriate standards at the open end of any test port cables and adapters that are connected to Port 1 or Port 2 of the instrument. This ensures that the match, phase length, and loss of these cables and adapters are all accounted for. For optimal performance, high quality phase‑stable cables and precision adapters must be used.
Figure: Return Loss Measurement before Calibration and Figure: Return Loss Measurement after Calibration compare a Return Loss measurement before and after the instrument is calibrated.
Note 
For accurate results, the instrument must be calibrated before making any measurements.
