Tektronix AA501/01 Distortion Analyzer Plug-In.
Measures level and also distortion to <0.0025%.
Power frames that this can be used in: TM 500, TM 5000.
Option 01: Intermodulation distortion measurements can be made in: SMPTE, DIN or CCIF. Automatically identifies these signals and selects the proper filtering circuit.
I tested this unit and it seems to be in good operating condition.
In the second picture I am measuring the sine wave signal from my FG 501A function generator.
NOTE: The power frame and FG 501A shown in the second picture are not part of the sale. The AA501 is the only item for sale.
A note about the "TESTED OK" sticker: I apply this sticker to items that I have varified working in the most basic way. I do not test all functions nor does this imply that the item has been calibrated.
There is no manual or other accessories supplied with this sale.
I am selling this unit without a right of return.
