The Tektronix Type 6R1A is a plug-in for the 567 oscilloscope. It replaced the 6R1. The 6R1A provides digital readout of time and voltage measurements on waveforms. The 6R1A (and the 567 in general) is oriented toward sampling measurements. The 6R1A is a counter and a comparator. To digitize analog voltages, the counter and comparator are used as a ramp-compare ADC. Card Q (Voltmeter) contains a 1MHz crystal oscillator. The counters (Card A) are made of flip-flops made of 2N1754 Germanium PNP transistors.
