Power rail probes (like Tektronix TPR1000) have very low input impedance (50 ohm) and high offset capability for measuring millivolt ripple on DC power rails without loading the supply or missing fast transients.
| Pin | Name | Function | Type |
|---|---|---|---|
| 1 | SMA Input | Power rail signal via 50 ohm connection | ADC |
| 2 | GND | Ground return via SMA shell | GND |
