Gxxx: 5 kV RMS High Precision Differential Probe (Option, to be ordered separately)
5 kV RMS, 20 MΩ, 50:1, 0.2% high precision, differential probe to be used in combination with GN610, GN611, GN610B and GN611B acquisition
cards. The built

in earthing monitor system increases safety of the user and protects the GEN series inputs for isolation overloads.
The probe is optimized to match the 33 pF input capacitance when using the ranges
