Learning To Use The CM2000
Computer Monitor Analyzer
The CM2000 Computer Monitor Analyzer
provides the ability to analyze computer
mon itors and isolate defective stages when
troubleshooti ng. This Tech Tip will quickly
familiarize you with the features and
operation of the CM2000 to get you started
making the best use of your Computer
Monitor Analyzer.
Connecting To A Monitor
The CM2000 SYNC & VIDEO OUTPUT jack
provides all the signals needed to connect to
the input terminal of a computer monitor.
Most computer monitors use one of several
standard types of input connectors. The in-

connector on the mon itor you are servicing.
See Figure 1 to select the interface connector
that matches the monitor you are servicing .
To connect the CM2000 to a monitor:
1. Turn off the power switch on both the
CM2000 and the monitor.
2. Plug the matching interface connector
into the SYNC & VIDEO OUTPUT jack.
3. Plug the monitor signal input cable into
the interface connector. If the monitor
does not have a cable, or if the cable is
too short, use the (optional) OUTPUT
EXTENSION CABLE between the SYNC
& VIDEO OUTPUT jack and the interface
connector.
4. Turn on the CM2000 (wait to turn on the
monitor until you have chosen the
signal format) .
.-----WARNING------.
Because many computer monitors use a
full-wave "hot chassis ," always plug the
monitor you are servicing into an isola-
tion transformer to protect yourself, the
monitor, and your test equipment.
Never isolate your test equipment as
this may defeat that protection .
Choosing The Signal Format
Each type of computer monitor receives a
particular set of signals from the computer it
is connected to. Th is signal format can be
classified by the type of computer or video
adaptor circuit which the monitor was de-
signed to work with .
