The crt of my Anritsu MS420K VNA will need to be replaced at some point. That is a given.
So I'm looking into LCD replacements.
Internally, the video signal is the ol' composite video, nowadays referred to as AVI. Handily, Anritsu provided a video output jack on the rear panel in case you wanted to use a larger, external crt. The same signal is sent to the internal crt.
So I bought a nice little LCD screen which used to be made by SuperCircuits. It's the right size, has AVI inputs, perfect.
Except - the image is offset vertically up and to the right, enough to clip off the top line of the display.
The SuperCircuits unit has some basic adjustments (bright, contrast, etc) but none for image positioning. I talked to them on the phone, this is a long-discontinued model, they didn't know what to suggest.
I'm a dummy when it comes to video protocols. Is this something that can be adjusted on the source end? The internal crt has adjustments but that doesn't change the video out signal.
Any help/suggestions would be appreciated.
