Page 8: The E5400-Pro Series Soft Touch Probes - At A Glance
Overview, Installation, and Selection of Probing Options The E5400-Pro Series Soft Touch Probes — at a Glance The new Keysight E5400-pro series soft touch probes are ultra-low-load connector-less probes that work with the Keysight logic analysis modules. The probes attach to the PC board using a retention module which ensures pin-to-pad alignment and holds the probe in place. - Page 9 The E5406A-pro series probe is a 34-channel single-ended connector-less soft touch probe (for analyzers with 90-pin cable connectors). Use the following information to design your target system board for use with the Keysight soft touch probes. Keysight Technologies E5400-Pro Series Soft Touch Connectorless Probes User’s Guide...
