Several museum volunteers have been working to restore our 567 Digital Readout Sampling Oscilloscope. This oscilloscope was first introduced in 1962 although this configuration of plug-ins didn't occur until 1968.

The 6R1A digital plug-in unit is used to measure waveform characteristics such as rise time, amplitude, or time difference. The digital unit provides a go/no-go output based on waveform characteristics making it useful in production testing.

There were approximately 1930 oscilloscopes produced with a latest serial number of 003280. This serial number is 003225 making it among the last 55 units produced. The price of this configuration in 1968 was $5650, or 52,191 in today's dollars.

Volunteer Tom Goodapple restored the oscilloscope function. Volunteer Bob Puckette is restoring the digital readout plug-in. It is operational but not fully verified. This is a great instrument to add to our exhibit area.

There are quite a few plug-in boards in the 6R1A plug-in.
