Opt. A2 – United Kingdom power
Opt. A3 – Australia power
Opt. A4 – 240 V, North America power
Opt. A5 – Switzerland power
Opt. A6 – Japan power
Opt. A10 – China power
Opt. A99 – No power cord or AC adapter
Connecting Power and Powering On/Off
This instrument operates from a single-phase power source with the neutral conductor at or near earth ground. The line
conductor is fused for over-current protection. A protective ground connection through the grounding conductor in the power
cord is essential for safe operation.
AC Power Requirements
The instrument operates from an AC line frequency of 50 or 60 Hz, over the range of 100-240 Volts, without the need for
configuration, except the power cord. (See page 2, International Power Plugs.)
The typical power draw is 50 Watts for a base unit. Refer to the Specifications and Performance Verification document for
additional information on power and environmental requirements.
Connect the supplied power cord to the rear-panel power connector. The instrument will turn on as soon as you apply power.
Press the Standby power button on the front panel to put the instrument in standby mode.

Installing the Monitor in a Video System
The instrument can operate almost anywhere in the distribution system. The following diagrams for serial digital systems and
for the analog composite inputs.
To install for monitoring the video bit stream
of a serial receiver:
1. Route the incoming serial signal into one
of the instrument SDI inputs.
NOTE. See the Specifications in the
Specifications and Performance Verification
manual for maximum allowed cable lengths.
Option Eye/Phy
SD and Option HD
WFM6100, WFM7000, and WFM7100 With Option FP Quick Start User Manual 3

Installation
To install for monitoring composite signals:
1. Connect your sources to the CMPST A
or CMPST B loop-through inputs on the
rear panel.
Option CPS
Line Termination
Your instrument uses passive loop-through analog and reference inputs. Accordingly, the loop-through inputs must be
terminated externally. It is important that this external termination meets accuracy and return loss requirements.
If the instrument is installed to monitor an operating link, the destination receiver and the connecting cable serve as the
termination. This monitoring connection checks the performance of the entire path. The return loss of the instrument is
sufficiently high that, in most cases, the destination receiver sets the system return loss.
In cases where the instrument is placed at the end of a link, a BNC termination must be installed on one side of the
loop-through analog or reference connector. The termination must be 75 Ωand DC coupled (good return loss extends to
DC). An appropriate termination would be Tektronix part number 011-0102-00. It is a 75 Ω, End of Line termination.
Compatibility of BNC Center Pins
Most video equipment BNC connectors, whether 50 Ωor 75 Ω,usea50Ωstandard center pin. Some laboratory 75 ΩBNC
connectors use a smaller diameter center pin. The BNC connectors on the instrument are designed to work with the
50 Ωstandard (large diameter) center pins.
Do not use connectors or terminators with the smaller center pins. They could cause intermittent connections.
