Hickok Model 215 Semiconductor Analyzer

This is where we talk about testing, measuring and repairing things. Sometimes we have to repair the equipment we use to test, measure and repair other things. It's an endless cycle of fixing the broken things we need to fix other broken things.

Hickok Model 215 Semiconductor Analyzer

Post by mediatechnology »

I found a manual for the Hickok 215 Semiconductor Analyzer. Hickok apparently had a lot of model 215s.

The 1976-era Hickok Model 215 may have been one of the first devices that allowed you to plug in a device, analyze its pin out and provide a good/bad indication. ebay is now full of similar devices using microporocessors: This one uses an octal counter to drive analog switches.

The devices are straight forward metal gate CMOS: 4001, 4016, 4022. The op amp is a 4558.

The "1/2/3" LEDs show which terminal is the control terminal (e.g. base, gate or UJT emitter.)
