FS: Audio Analyser National Instruments board & software

[AD]

For sale is a fully working exc. condition National Instruments Dynamic Signal Acquisition and DSP board for ISA, model AT-DSP2200 and attached is also Virtual Bench software, which make together an excellent Audio equipment measuring system.

Selling price 180 US$.

You can download the manual at the National Instruments website as their pdf file number 320435 .

This is an excellent board to make really low noise, low distortion measurements on audio equipment.
The board has a 93 dB dynamic range and THD of only -95dB, but with software sampling it can measure down to -120 dBV.

The one and important limitation with this board, being an old type, *is that it can only be used in a PC with an ISA slot and the newest software running Windows 95, 98 or NT* !

I will ship the board, the required Ni-Daq software on a CD, Virtual Bench software for Win 95 on floppy discs and the Virtual Bench certificate (you can upgrade for free to Win 98 version on NI website).
