Tektronix AA501
Distortion Analyzer
Description
The Tektronix AA501 is a Distortion Analyzer that has a measurement of level, total harmonic distortion plus noise (THD+N).
Select the mode and the rest is automatic. The unit will let readings be expressed in true rms or average response and rms calibrated. Any one of four built-in frequency-weighting filters can be switched into the signal paths for preconditioning of the signal to be measured. The provision is also made to permit the use of a user-selected filter.
Other features are input monitor, function output, and auxiliary input connectors. It uses 2 slots in the Tek TM-Series Power Module.

Specifications
The fundamental frequency range is 10Hz to 100kHz, with harmonics measured out to 300kHz.
The distortion ranges are auto (100%), 20%, 2%, 0.2%, and dB (autoranging).
The digital voltmeter has input range of 200 µV to 200 V (10 steps) plus auto range and will display signal level in volts, dBm, or dB ratio
