WFM90D • WFM91D

The Tektronix WFM90D/WFM91D are

handheld, multifunction monitors ideally suited

to the monitoring needs of field production,

equipment installation or any situation where

portability and battery operation is required

for analysis of analog composite video and

270 Mbps – SDI systems. The combination

of features and monitoring modes provided

makes these instruments powerful enough to

set up, time and troubleshoot complex video

and audio systems, combining the power of

four separate instruments in the palm of

your hand.

The high-resolution, 4 in./102 mm color LCD

display provides a clear picture of the incom-

ing video signal. Alternately, the waveform,

vector or audio displays may be shown full-

screen or any one may be cut into any corner

of the display. In addition to the LCD display, a

composite video output supplies a mono-

chrome waveform, vector or audio display,

either full-screen or cut into a color picture.

Handheld Waveform Monitors

WFM90D •WFM91D

As a waveform monitor, the WFM90D/

WFM91D provides all the features expected

on a basic, single-channel monitor: external

reference; 1H, 2H and 2F sweeps; X1, X5 and

variable vertical gain; flat and luminance filters.

The external reference input allows users to

perform the system timing adjustments critical

to sophisticated field productions. In addition

to these basic features, an alarm mode, where

the waveform’s color changes above 100 IRE

(WFM90D) or 700 mV (WFM91D), provides

quick feedback when video levels exceed

accepted standards.

The WFM90D/91D also reports presence/

absence of EDH packet, FF/AP CRC Errored

Seconds and Cable Length Margin Flag.

All display controls are selected through

simple, on-screen menus.

Whether adjusting a camera’s black/white

balance or adjusting chroma levels and hues

on a time base corrector, the WFM90D/

WFM91D Composite Vector Mode provides

the needed display controls. Variable, X1

and X5 gain settings and a 360 degree phase

shifter are selectable via on-screen menus,

as is 75% or 100% bars for the WFM90D.

The Analog Audio Mode’s voltage vs. time

display is useful for setting or checking levels

and for detecting certain types of distortions.

The audio display, driven via a single XLR

connector and a headphone jack, permits

listening to the displayed audio.

WFM90D/WFM91D monitors can be powered

with a NiMH battery pack or an AC adapter,

which also charges the NiMH battery pack.

A 12 volt cigarette lighter adapter may also

be used as a power source.

A rugged case with a shoulder strap makes

transporting WFM90D/WFM91D monitors

easy. Several options are available for the

WFM90D/WFM91D monitor, including a

viewing hood for operating in bright light and

a desk stand that simplifies benchtop use.
