High-voltage differential probes have two SMA inputs (+ and -) and BNC or SMA output, measuring the voltage difference between two arbitrary points in a circuit without ground reference issues.
| Pin | Name | Function | Type |
|---|---|---|---|
| P | Positive Input | Differential positive probe point | ADC |
| N | Negative Input | Differential negative probe point | ADC |
| OUT | SMA Output | Attenuated differential signal to scope | ADC |
| GND | GND | Instrument ground reference | GND |
