In the R&S XSRM Rb-standard (which I have), the 0 - 10V input goes straight into the resistor network and coil setup as you described. The range is 1E-9. Pretty much as your FRK-L modification, but this one is standard issue and comes with a BNC in the back, as you would prefer. PS. Anyone got the manuals for the frequency-converter XSRM-Z and the phase- comparator XSRM-Z3? I would enjoy having them. Have the XSRM RB-standard and XSRM-Z PSU manuals with schematics.
