The Tektronix 442 is a 35 MHz dual-trace oscilloscope with a single timebase.
The anode voltage on the CRT is 10kV and the standard phosphor was P31.
A Tektronix 442 consumes 36 watts and weighs about 20 pounds.
Triggering is done using a trigger amplifier made of discrete bipolar transistors and a 74S00 TTL quad NAND gate configured as a flip-flop.
The power supply is linear and regulated using op amps as error amplifiers.
The vertical and horizontal amplifiers are made of discrete bipolar transistors except for the dual-JFETs that are used as high-impedance buffers at the signal inputs.
