It is still useful information! Thanks to all.
I have a Velleman two channel digital scope that runs on the USB on a computer. It will do X-Y and I may try that for the units that have analog outputs.
However for the 4815A I need two verticals and a horizontal because it plots Z and Phase. Using the Velleman as a dual I/P scope with a matching sweep speed and triggering it from the 4815A may work, but sounds tricky.
I wonder about building a PIC circuit to record Impedance, Phase, and Sweep and then sending this to another program (Excel?), or has someone done this? Perhaps the old plotter is easier. I have seen various adapters to get away from the HP pens that dry out after a year even if unused. They are also entertaining to watch.
Peter.

So I looked up the 4815A and it does not have a screen. My reply below was only meant for instruments with a screen. Sorry
