The goal is not to have all of the test equipment, or none, but to have the right test equipment.


Footprint is important. You will want to spend some time thinking about Storage. Try to get equipment that has a digital interface, so that you can automate your setup.

Specific Equipment

Curve Tracer

Don't buy one without GPIB/USB/Serial. Useless for documentation.

DVM

Density = Mass over Volume. Are you dumb?

Load

dummy load in a bucket of water (drum) with enameled wire (must be enameled to allow for the heat to dissipate, whereas plastic coated wire would melt the insulation first).

Oscilloscoop

Vector Network Analyzers

Tips/Techniques

Consider Digital Interfaces for All Equipment

If you want to get serious work done, you are probably going to want to script or automate your setup. So beware of old Bench DMMs, function gens, and other equipment that doesn't have at least a GPIB interface.

Output of equipment at 0 Volts

Try to Support Local Businesses

If there is a vendor of a tool or TE near you, then buy from them.
