N OTE support your probe, fix known defects, and incorporate product enhancements. To download the latest firmware, go to www.keysight.com, locate the Technical Support page, and search by your oscilloscope model number. The N2804A and N2805A probes are designed for oscilloscopes with 50W N OTE AutoProbe-interface channel inputs.
Disconnect the probe from the oscilloscope and clean the probe with a soft cloth dampened with a mild soap and water solution. Make sure that the probe is completely dry before reconnecting it to an oscilloscope. N2804/5A Differential Probes User’s Guide...
