Installation Considerations
The waveform monitor is shipped in a wrap-around chassis that covers the
instrument bottom and two sides. A cover is installed on the chassis, and the rear
panel is made up of the module rear panels.
You can operate the waveform monitor in the instrument chassis (be sure the top
cover is on) or installed in an approved portable cabinet or rack adapter. (See
page 17, Rackmount Installation.) You can also install the waveform monitor in a
custom installation, such as a console.
CAUTION. To prevent damage to the waveform monitor and the cabinet, do not
install the waveform monitor in any cabinet except those that are approved by
Tektronix, such as the WFM7F02 and WFM7F05.
If you install the waveform monitor in a custom application, such as a console, be
sure to provide adequate airflow. Follow these guidelines:
Do not block the ventilating holes.
Adhere to the clearance requirements. (See Table 2 on page 7.)
System Installation The waveform monitor can operate almost anywhere in the video distribution
system. To monitoring the video bitstream of a serial receiver, route the incoming
serial signal into one of the waveform monitor SDI inputs.
To monitor serial digital signals around a routing switcher, connect your serial
sources through a patch panel to a serial router. Connect the output of the serial
router to an SDI input for comparison.
Line Termination The waveform monitor uses passive loop-through analog and reference inputs.
Accordingly, the loop-through must be terminated externally. It is important that
this external termination meet accuracy and return loss requirements.
If the waveform monitor is installed to monitor an operating link, the destination
receiver and the connecting cable serve as the termination. This monitoring
connection is best because it checks the performance of the entire path. The
return loss of the waveform monitor is sufficiently high that, in most cases, the
destination receiver sets the system return loss.
In cases where the waveform monitor 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
extendstoDC).Returnlossshouldexceed40dBfromDCto6MHzfor
composite. An appropriate terminator would be Canare part number BCP-TA. It
is a 75 Ω, 1%, BNC, 26 dB return loss to 2 GHz, end-of-line termination.

System Integration
Compatibility of BNC
Center Pins
Most video equipment BNC connectors, whether 50 Ωor 75 Ω,usea50Ω
standard center pin. Some laboratory 75 ΩBNC connectors use a smaller diameter
center pin. The BNC connectors on the waveform monitor are designed to work
with the 50 Ωstandard (large diameter) center pins.
CAUTION. To prevent intermittent signal connections, do not use connectors or
terminators with the smaller diameter center pins.
Power and Environmental Specifications
The waveform monitor 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.
NOTE. Power systems with both current-carrying conductors live with respect
to ground (such as phase-to-phase in multiphase systems) are not recommended
as power sources.
The waveform monitor does not need any power configuration, except for
using the proper power cord for your installation site. Refer to the WFM6100,
WFM7000, and WFM7100 Waveform Monitors Quick Start User Manual for a list
of the available power cords.
To connect power to the waveform monitor, insert the supplied power cord into
the rear-panel power connector. There is no power switch on the waveform
monitor, so the instrument will turn on as soon as you apply power.

Connector Specifications
The waveform monitor has connectors on the front and rear panels. The following
pages describe the connector types, pin numbering, and associated signal
requirements.
SDI Video Connectors Use the SDI A and SDI B inputs to connect a serial digital video signal to the
instrument. The SDI Out signal is the switched output of the selected SDI A or
SDI B input signal and has the same data rate as the input signal. Use the IN/OUT
menu to configure the SDI Out signal to be either the looped-through input signal
or the Pix Mon signal output, which contains configurable error brightups.
The Clock Out connector (Option EYE or PHY only) outputs the data rate of the
selected SDI input signal. You can connect the Clock Out signal to a spectrum
analyzer to view jitter frequency components in the video signal. The following
table lists the characteristics of the SDI video connectors.

connectors are input only. You can configure the "B" connectors to function as
an additional input or as an output of the audio signal being input on the "A"
connectors. Use the Audio Settings menu to configure the channel mapping in
the audio displays.

Analog Audio Connector Use the ANALOG AUDIO connector to input or output analog audio signals. Use
the Audio Settings menu to configure the channel mapping in the audio displays.
The following table lists the signal characteristics of the Analog Audio connector.
For all audio options except Option DS, use the supplied 62-pin DSUB connector
to attach analog-audio signals to the instrument. Solder wires to the connector as
needed to accommodate the desired audio inputs and outputs. Audio signals can be
connected as either balanced or unbalanced. Be sure to use a suitable cable when
you are wiring balanced audio. An example of a suitable cable is Belden 8451,
which is a shielded twisted pair cable. Alternatively, you can purchase an audio
breakout cable (Tektronix part number 012-1688-00), which provides a two meter
cable with XLR connectors for all twelve inputs and eight outputs.
