- Notes
-
The 82 dual trace plug-in amplifier was intended for the 580-series of high speed oscilloscopes. Depending upon the gain, the bandwidth extended from DC up to 85 MHz.
The unit has channel A, channel B, chopped or alternate operating modes.The front end of the Type 82 is a cathode-follower (7586 nuvistor), followed by bipolar diff-amps and diode channel switching, followed by a distributed output amplifier made of three 6DJ8 tubes, with differential 93 Ω outputs feeding the input of the mainframe's delay line driver distributed amplifier.
The top three least sensitive positions have restricted frequency response.
For proper performance of the 82, 581/585 scopes with serial numbers before 2585 should have the back termination of the final distributed amplifier output modified to the later circuit.
