Chapter 7 — Calibration, VNA
7-1 Introduction
This chapter provides details and procedures for calibrating the Vector
Network 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 will ensure 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.
Note
For accurate results, the instrument must be calibrated before
making any measurements.
Note
Screen images in this User Guide are illustrations of typical
instrument features. Some images may include instruments other
than the Site Master S820E. Traces and other display features
may differ from the screen displays of your instrument.
