Choosing An Appropriate Output Cable - Keysight N7040A User Manual

Choosing an Appropriate Output Cable

The N7040A/41A/42A probes are shipped with a 0.5m BNC to BNC 50 Ω cable to establish
connectivity between the probe and oscilloscope.
If needed, you may use a longer cable that meets the requirement of a 50 Ω single screened coaxial
cable type.
Also, though the use of extension cables may not be problematic from the noise viewpoint but
consideration should be given to the routing of very long cables.
