Remote Interface
Remote Interface allows all manual adjustments to be controlled. The
results of the VDA measurements (AMC & CRM) and the result of
detecting the DC voltage level in the HFMIC path, are available as output
on the interface.
Use a PC to control the JBD–2 from the IEC–to–Parallel interface.
For example: “ICS 4863 - GPIB Parallel Interface”
