DC signals played out on the RMx analog outputs quickly decay to zero

Issue

The RMx devices are not able to play out DC or very low frequency (<1 Hz) signals. This is because of a 0.16 Hz highpass filter on the D/A converter. Also, because of the roll off of this filter, users may see attenuation in signals played out with frequencies less than 10 Hz.
