TS-34 Oscilloscope/ AP from the US

Here we have an interesting exhibit. This is a US made (110V) oscilloscope where the display tube is viewed from one end, through an illuminated graticule and a large optical lens assembly. The tube itself only being some 2 inches in diameter.

In keeping with all the Radar Rooms equipment, we like to find each one a different way of being demonstrated. In the case of this unit, we thought it appropriate (noting the country of origin) that we simulate the radar screen as it was seen on the Opana Point radar just before the Pearl Harbour raid in 1941. Please note that the actual set used to display the radar image was not a TS-34 like this one, but a BC403A oscilloscope forming part of the SCR-270 radar system. This gave an ‘A’ screen display like the ‘Chain Home’ stations, but had the contacts shown as positive going blips.

There are no controls on the front panel as there is no front panel so to speak. All controls being evenly distributes down both sides of the case with a fixed mains lead at the bottom.

This is a square waveform being viewed through both graticule and lens assembly.

And now a sine waveform.
