1. Vsupply is equal to 5 V, solder attached.
2. Max current varies with max resistor power rating. The examples in the table assume 500 mW power rating.
3. With scope with high resolution mode on, sampling rate < 2.5 MSa/s, 20 MHz low pass filter on.
4. Infiniium V, 90000A, 90000 X-, and 90000 Q-Series are not compatible with N2820A/21A current probe.
5. Denotes warrantied specification after 20-minute warm up. All others entries in the table are characteristics.
