The Keysight DSAZ634A is a 63 GHz digital signal oscilloscope built on the Infiniium Z-Series platform for real-time acquisition and analysis of high-speed signals. Leveraging RealEdge technology with indium phosphide semiconductor architecture, it delivers superior signal integrity, minimal jitter, and low noise floors. The instrument captures complex waveforms and transient events across two or four channels with configurable bandwidth and sample rates, supported by up to 2 Gpts of acquisition memory and a 15.4-inch capacitive touchscreen display.
