This test equipment is vintage, analog and designed for use with the now discontinued Teletext broadcast system
Museum piece, perhaps modified to a specific purpose or for parts (e.g CRT)
UNAOHM Video Teletext Analyser
Model EH-1000
Designed & Manufactured in Italy
Professional Teletex Data Analyser
Although designed for 220V working, I did run some quick tests at 240V and had no issues although to be safe for long term use, this equipment should be run via a variac or stepdown 240 - 220V
There is no manual but after observing the unit operation and the various controls I can tell you this is a Video Analyser intended for specifically examining teletext signals that were broadcast along with the normal television video signal.
Actually this is more like a complete television/video signal analyser but designed to specifically look at the data signals carried by various lines (you can manually select every line from 0 to 625)
You can use this unit to observe the teletext information, waveform etc on any line and also the analog broadcast video signal with audio.
You can input either direct RF (off air) or IF or Video and have a look at it. This unit is NOT suitable for digital transmissions, analog only.
The CRT is green, no colour pictures here!
When I tested this, analog television was still being broadcast and I found a signal - CRT display was good, stable and sharp - just GREEN!
Besides watching the video signal, you can hear the audio (amp/loudspeaker is built in).
Most of the controls are concerned with the teletext information e.g line select, data controls etc but the usual basic intensity, focus, X & Y axis are all there as well.
No problems with intensity, focus or the X & Y controls - all good
Measures 30cm x 18cm x 42cm
Weights approximately 15Kg
Originally there was a metal front panel cover - this is not included
Front panel controls-knobs-switches all fine
Labelling clear and undamaged
CRT has proper function, lots of brightness-focus
X & Y axis positioning all working
Interesting VINTAGE test equipment for the collector or perhaps for modification to suit a specific need. The internals are all well laid out and accessible, for example it would not be hard to change the RF tuner unit to suit other systems.
