	I work on small signals of less than micro volts.  I use a computer
to control my experiment and take data via IEEE bus.  One of the equipments
in my setup is a digial ratio transformer made my Eaton Advanced Electronics.
This equipment was designed so poorly that a ten-times larger noise was
added to my circuit if I added it to my IEEE bus.  
	I would like to find a way to add the digital ratiotran to the IEEE
while the noise is isolated only to the ratiotran.
	Will an optical isolation work in my case?

	Thanks in advance for any advices.
