The Tektronix 284 is a pulse generator. | 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 [[Connectors#GR-874|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. | |||
