The Tektronix 107 is a squarewave generator introduced in 1958.
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 mVp-p (variable) into 50 Ω |
|---|---|
| Rise time | less than 3 ns (fixed) when terminated into 50 Ω |
| Repetition rate | 400 kHz to 1 MHz (variable, 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.
