RIGOL DSO1054Z, 50 Mhz Oscilliscope (quad channel) 

TEKTRONIX 2205, 20 Mhz Oscilloscope (dual channel)

These pieces of equipment are used to look at audio signals, power supply and output mosfet drive signals, and many other things. This is a must have tool when working with class "D" equipment to ensure things are working properly.

UNITUT61E DMM

This tool is a multifuction digialt multimeter. It is used for checking both AC and DC voltages on various components as well as measuing resistnace, checking diodes, and quickly checking operating frequencies.

UNIT UT204

This tool is a auto-ranging AC DC True RMS handheld clamp meter. It is used for measuing current flow in conductors.

CRAFTMAN 82141 DMM

This tool is used as a back up to the UNITUT61E.

POWER SUPPLY

We utilize a custom power supply that has variable voltage from 12-13.6 volts and is capable of producing 160+ amps of continuous power. This supply works great for testing most amps at the work bench. Larger amps requiring more robust testing at high power levles are hooked up to a 14 volt xs power d1400 battery bank with a few banks of Maxwell Ultracaps to sustain voltage even under the highest demands.

LOAD

For load testing we use a custom built water cooled resistive load bank. With the current setup we are able to meausre output up in the 19,000 watt RMS continuous power range at a 1 ohm nomial load.
