  • Equipment Installation The Tektronix WFM90 Series 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 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, four-inch/102 mm color LCD display provides a clear, unprocessed picture of the incoming 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 monochrome waveform, vector or audio display, either full-screen or cut into a color picture. As a waveform monitor, the WFM90 Series provides all the features expected on a basic, single-channel monitor: external reference; 1H, 2H and 2V 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 (WFM90) or 700 mV (WFM91), provides quick feedback when video levels exceed accepted standards. 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 WFM90 Series' 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 WFM90. The audio mode's voltage vs. time display is useful for setting or checking levels and for detecting certain types of distortions. The audio display is driven via a single XLR connector, and a headphone jack permits listening to the displayed audio. WFM90 Series monitors can be powered with a NiCad battery pack, six alkaline C cells or an AC adapter, which also charges the NiCad 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 WFM90 Series monitors easy. Serial options are available for the WFM90 Series monitor, including a viewing hood for operating in bright light, and a desk stand that simplifies benchtop use.
