playrectdt

Plays and/or records on Tucker Davis Sytem 2 hardware.

Useful if you do all your signal generation in Matlab, and you only want to use your Tucker Davis hardware for a-d/d-a.

The number of d-a channels to use is specified by the number of input arguments supplied The number of a-d channels to use is specified by the number of output arguments supplied

If you want only to record, pass an array of zeros as input to specify the number of samples to record

Values outside the range of ±32767 are clipped.

If present, pf1's are set to bypass, and pa4's are set to 20 dB of attenuation

usage example:

[a,b] = playrectdt(noise,tone,32768);
...plays the vector noise on d-a channel 1, the vector tone on d-a channel 2, and records from both a-d channels
