Characteristics - Keysight N2791A User Manual

Characteristics

Characteristics for the N2791A and N2891A high-voltage differential probes are
shown below. The probe / oscilloscope should be warmed up for at least 20
minutes before any testing and the environmental conditions should not exceed
the probe's specified limits.
