Unfortunately I was unable to find one either. The command structure "may" be similar enough between the two instruments such that the 8753A will work. If not then you have a couple options. You can submit a request for this driver at:
http://zone.ni.com/idnet/other.htm
We develop drivers based on demand and popularity so the more requests we have for it, the greater the possibility that we will develop one.
If you would like to try developing your own instrument driver (or modify the existing one), we have documentation, model instrument drivers, and driver templates to help at :
