Portable Waveform Vectorscope: Tektronix WFM-90 — $50/day
by IEBA on Jul.14, 2009, under Rental Gear
This handy little item is a combination waveform, vectorscope and audio scope all in one. The little 4″ LCD is not much to crow about these days- it’s not OLED like a Sony Walkman or Samsung phone, but you can loop the output of this device to the screen of your choice (composite in and out).
So if you have a composite NTSC feed of your video, this portable device can measure it and give you calibrated IRE readings, vectors for calibrating bars or color charts and more. All this off any 12v supply (AC adapter included.)

Dual field Waveform. I prefer single field.

Vectorscope on camera bars. Nice.
