We have an old test system used to automate the testing of certain devices. Some instruments in the system are old and need replacing. But the units are neither serviceable nor replaceable, So we need to find new hardware.
But again We cannot edit the code of the control software to add in the commands for the new hardware. So, I want to make a little black box which will sit between the controller and the new instrument and translate the old GPIB commands to modern SCPI commands and transmit via ethernet.
So my black box will need to act as both an instrument and a controller in order to pose as the old instrument but then control the new instrument, but also work in reverse to send the reading back to the controller.
If i make system like that how old system will identify my system as test instrument. What settings i should do for that
