BBC Portable Attenuator

eve-bbc-portable-attenuator-patOne of a number of different attenuators designed by the BBC, the portable PAT/3A was intended for the test engineer in the field.

Extremely useful for ‘padding down’ the input of other fixed gain BBC equipment such as Type A and Type B valve amplifiers.

Note the screw terminals which were common on outside broadcast and field test equipment.
