5520A
Service Manual

1-2. Operation Overview

The 5520A Calibrator may be operated at the front panel in the local mode, or remotely
using RS-232 or IEEE-488 ports. For remote operations, several software options are
available to integrate 5520A operation into a wide variety of calibration requirements.
1-3.

Local Operation

Typical local operations include front panel connections to the Unit Under Test (UUT),
and then manual keystroke entries at the front panel to place the calibrator in the desired
output mode. The front panel layout facilitates hand movements from left to right, and
multiply and divide keys make it easy to step up or down at the press of a single key. You
can also review 5520A Calibrator specifications at the push of two keys.

Remote Operation (RS-232)

There are two rear-panel serial data RS-232 ports: SERIAL 1 FROM HOST, and
SERIAL 2 TO UUT (Figure 1-2). Each port is dedicated to serial data communications
for operating and controlling the 5520A during calibration procedures. For complete
information on remote operation, see Chapter 5 of the 5520A Operators Manual.
The SERIAL 1 FROM HOST serial data port connects a host terminal or personal
computer to the 5520A. You have several choices for sending commands to the 5520A:
you can enter commands from a terminal (or a PC running a terminal program), you can
write your own programs using BASIC, or you can run optional Windows-based software
such as 5500/CAL or MET/CAL. The 5500/CAL software includes more than 200
example procedures covering a wide range of test tools the 5520A can calibrate.
The SERIAL 2 TO UUT serial data port connects a UUT to a PC or terminal via the
5520A (see Figure 1-3). This "pass-through" configuration eliminates the requirement for
two COM ports at the PC or terminal. A set of four commands control the operation of
the SERIAL 2 TO UUT serial port. See Chapter 6 of the 5520A Operators Manual for a
discussion of the UUT_* commands. The SERIAL 2 TO UUT port is also used to
connect to the Fluke 700 series pressure modules.

Remote Operation (IEEE-488)

The 5520A rear panel IEEE-488 port is a fully programmable parallel interface bus
meeting standard IEEE-488.1 and supplemental standard IEEE-488.2. Under the remote
control of an instrument controller, the 5520A Calibrator operates exclusively as a
"talker/listener." You can write your own programs using the IEEE-488 command set or
run the optional Windows-based MET/CAL software. (See the 5520A Operators Manual
for a discussion of the general commands available for IEEE-488 operation, and
Chapter 3 of this manual for remote commands used for 5520A calibration.)
