284
The Tektronix 284 is a pulse generator. Its output modes include:
- 70ps risetime pulse, 200mV
- 1GHz sine wave, 100mV
- 100MHz sine wave, 100mV
- 10MHz square wave, 10mV, 100mV, or 1V
- 1MHz square wave, 10mV, 100mV, or 1V
- 100kHz square wave, 10mV, 100mV, or 1V
Only one mode can be used at a time. The pulse comes out one output connector. The sine wave and square wave come out another output connector. Both outputs are 50-ohm GR-874.
The 284 generates a 1GHz sinewave using an 2N3478 RF NPN transistor-based oscillator.
The 284 generates the fast pulse using a 152-0329-00 21mA tunnel diode.
