HP 8903A Audio Analyzer
Versatile measuring machine, in excellent condition:
-Measures true rms volts, dc volts, frequency
-Programmable low distortion source
-Measures distortion, SINAD, signal to noise
-Misc. built-in filters
-HP-IB bus and plotter connections (on the back, photo 10)
-The instruction cards are both present (photo 2)
See photo 1 for THD (distortion) of the internal generator as measured by the internal analyzer: as low as it should be:
around 0.002% and even lower here for this unit.
Search (google) for more about that low THD for "AUDIO MEASURING SYSTEM BASED ON HP 8903A" The fix described there is therefore not necessary because with this unit since it's even below that 0.002%
See photo 2 for output signal (that oscilloscope is obviously not part of this advertisement ).
Asking EU440. Item is located in The Netherlands.
Shipping (at buyer's expense & risk, shipping after credit to my own account) - I will only ship this device with insured shipping.
Local pick up possible as well (cash or after having received on my own account).
Just contact me if you have questions.
Thanks for the interest, and have a nice distortion-free day.
