The Agilent HP Keysight U4204A is a connectorless logic analyzer probe from the Soft Touch Pro Series designed to expand digital signal analysis capabilities for integrated system debugging. This 34-channel probe—comprising 32 single-ended data channels and 2 clock channels (single-ended or differential)—connects directly to compatible logic analyzer modules for efficient signal acquisition from devices under test. The probe supports data rates to 3.2 Gbps with minimal circuit intrusion through high input impedance and excellent transient noise immunity.
