Description The AA501 Distortion Analyzer provides measurement of level, total harmonic distortion plus noise (THD+N). Operation is made simple, select the mode and the rest is automatic! 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 unit allows readings to be expressed in true rms or average response and rms calibrated. Any one of four built-in frequency-weighting filters may be switched into the signal paths for preconditioning of the signal to be measured. Provision is also made to permit the use of a user-selected filter as well. The digital voltmeter has input range of 200 ?V to 200 V (10 steps) plus auto range and will display signal level in volts, dBm, or dB ratio. Other features include input monitor, function output, and auxiliary input connectors. It utilizes 2 slots in a Tek TM-Series Power Module FEATURES : 10 Hz to 100 kHz frequency range Harmonic measurements to 300 kHz 200 µV to 200 V input range ACCURACY input > 4% of Range: 20 Hz TO 20 kHz ±1dB, 10 Hz TO 100 kHz +1dB, -3dB 100%, 20%, 2%, 0.2% distortion ranges I'm not an expert on these units but I connected it to an oscilloscope and a signal generator and everything appears to work and the settings appear to be correct. I haven't had it professionally tested so I'm not guarranting it for accuracy. It was last calibrated in 1996. Formerly used by a large US Government defense contractor. This unit is VERY clean except for two "Property Of" stickers (on the top and side). The front panel is in like new condition with no cracks, damage, etc. It does have one small Tektronix Calibration sticker on it. Pictures are of the actual item. Free local pickup in Orlando area. Flat rate shipping via FedEx in the continental US. PR, Hawaii, and Alaska will be higher. I charge only actual shipping costs, No handling or packing charge or excessive shipping costs. International shipping will vary by location AND postal requirements. Estimated shipping weight is 8 pounds. See my other auctions for the companion Tektronix SG505 Oscillator that was in the rack with this unit.
