Test Equipment

For people who just can't get enough cool tools, here's the beginning of my personal "review" collection! Theimportance of these particular items is their affordability.

From GTC Industries, pocket-sized audio generators
 

TONE PLUG: Mini-oscillator in a male XLR connector

NOISE PLUG: Pink Noise generator in a male XLR connector

From Neutrik Test Instruments...

The Minirator, MR-1, a precise, low-distortion sine + multifunction hand-held oscillator, available in two flavors:

• MR2: MCM Electronics part number 72-8600 for $360
• MR-PRO: MCM Electronics part number 72-8605 for $588

The Minilyzer ML-1, a multifunction hand-held audio analyzer that measures level in RMS volts, dB, S/N, THD, spectrum analysis and an oscilloscope. 

• MCM Electronics as part number 72-6758 for $675.

Also available from MCM Electronics...
 

The 72-505 is a $67 stepped-frequency oscillator.  At .03% distortion, it is cleaner than mant multi-function oscialltors and very affordable.
