9-1 INTRODUCTION
This chapter provides a general description of the AutoCal
calibrators, including specifications, setup, and the use of the
associated software and on-line documentation. The RF series
members are shown below. Throughout this manual, the term
AutoCal will refer to the series. Individual models will be referred to
by model number. Figure 9-1 shows the AutoCal module and all of its
attaching parts.

9-2 DESCRIPTION
The AutoCal module provides an automatic system for fast,
repeatable high-quality calibrations of a Vector Network
Measurement System (VNMS). The AutoCal module is inserted
between the VNMS test ports to perform the calibration. The AutoCal
module is connected between Ports 1 and 2 (3-Port and 4-Port
AutoCal procedures are found in Section 9-8). Refer to Figure 9-2
(page 9-6) for a diagram of the AutoCal connections.
The AutoCal module use solid-state electronic switches to exchange
the internal calibration standards. The module does NOT contain
isolation standards and requires a manual operation to perform this
measurement.
A standard serial RS-232 interface cable is used to connect the
AutoCal module to the MS462XX. Power is supplied by a connecting
cable from a Universal power supply (+5V, +15V, -15V for the
electronic modules; +5V, +24V for the mechanical modules). A power
on-off switch is not provided. It is important to connect the power
supply connecting cable to the AutoCal module BEFORE the power
supply is connected to the wall outlet.
