Chapter 7 — Calibration
7-1 Introduction
This chapter provides details and procedures for calibrating the
Cable-Antenna Analyzer modes of the Site Master S331L. Topics
include calibration options Internal InstaCal, External
Open-Short-Load (OSL), Transmission using External Sensor,
Standard Cal, and Flex Cal.
Anritsu recommends connecting a phase-stable test port cable (3 meters
maximum length) to the RF Out/Reflect In connector and calibrating at
the open end of the cable using the Site Master S331L internal InstaCal
or external OSL components. Calibrating at the end of the test port
cable will remove ripple and loss associated with the cable. Using a
phase-stable cable allows the cable to be physically moved without
affecting the measurement.
Figure 7-1 on page 7-2 compares the Return Loss measurement of an
open phase-stable cable before and after calibration.
