Yes.  The device supports a SCPI command set.   The next version of Lady Heather supports it... well at least my modified Z3812A does.

You probably don't need an RS422 converter.   You can cobble an RS-232 connection into the RS-422 port.  This usually works, but some hardware serial ports have voltage threshold issues reading data from the device (the RS-422 signals don't swing as much as the RS-232 ones do).  All my USB-serial dongles work well, but I have had some issues with genuine hardware serial ports.
