107: Difference between revisions

Revision as of 05:13, 6 July 2018

The Tektronix 107 is a squarewave generator introduced in 195. It is designed to provide a clean waveform with fast edges and flat tops for the calibration of oscilloscopes.

Key Specifications

Output	rectangular waveform, 100−500 mV_p-p (variable) into 50 Ω
Rise time	less than 3 ns (fixed) when terminated into 50 Ω
Repetition rate	400 kHz to 1 MHz (uncalibrated)
Weight	5.9 kg (13 pounds)
Power	100 W

Internals

The signal path starts with an astable multivibrator composed of both halves of a 6BQ7A dual triode tube. The multivibrator circuit is cathode coupled to a pulse shaping circuit, and then to an output stage made from a single 6AU6 tube with a 50 Ω plate load, providing a controlled 50 Ω output impedance. The 50 Ω plate load keeps the voltage gain of output stage low, and the bandwidth high.
