• Notes
• Unit has six 6CW4 Nuvistor tubes in the signal path and numerous transistors in the switching circuits. This unit has nine calibrated switch-selected sensitivity ranges, from 0.05 V/cm to 20 V/cm with an additional vernier adjustment that extends the sensitivity to 50 c/cm. While working in a model 175A oscilloscope with a native frequency response of 50 MHz, this unit has both AC and DC coupled frequency response of only 40 MHz, so even though its introduction date is somewhat after that of the 'scope, it cannot drive the 'scope to its full capabilities.
