The Tektronix 7704 is a 150 MHz, four-bay mainframe introduced in August 1969 that can take two 7000-series vertical plug-ins and two 7000-series horizontal plug-ins. It was superseded by the 7704A in 1973.

Key Specifications

Fastest cal. sweep	2 ns/Div
Bandwidth	150 MHz (with 7A11 or 7A16)
Calibrator	4 mV to 40 V in decade steps, 2/20/200/400 mV into 50 Ω, 40 mA; 1 kHz
Outputs	Vertical Signal Out (25 mV/Div, 60 MHz), +Sawtooth, +Gate, Cal, camera power, probe power
Z Axis input	two: High Speed (60 V_p-p, DC-100 MHz), High Sensitivity (2 V_p-p, DC-2 MHz; 0.4 V_p-p @ 20 MHz)
CRT	154-0609-00, 8 cm × 10 cm graticule, distributed vertical deflection plates, P31 phosphor standard
Acceleration voltage	24 kV (+21/-2.96)
Power	90-136 V or 180-272 V, 48-440 Hz, 210 W max.
Weight	19.1 kg (42 lbs)
Size	34.2 cm × 30.5 cm × 35.1 cm (H×W×L)

Internals

The 7704 uses an all-discrete switch-mode power supply (SMPS) in resonant half-bridge topology. The CRT voltages and heating are produced in a separate switching stage running off the main SMPS DC output.
