Derek, Voltage probe is a very simple device comprising capacitor, resistor and optional inductor. Description and circuit diagram are given in CISPR Publication 16-1. If you need copy of relevant two pages, please let me know. I would suggest to protect front end of your analyzer by having it connected to the voltage probe only for a short period of time during measurements and avoid to shut off EUT during that period.
You could also protect front end of analyzer with commercially available pulse limiter (could cost as much as 2nd hand LISN) or you could make one from discrete components (two resistors and two diodes). I would also suggest to compare power line disturbance levels of a EUT with a current of less than 30 Amps measured with a voltage probe and a LISN to establish correlation.
