The Agilent/Keysight U1604B is a portable handheld oscilloscope that integrates dual-channel waveform capture, true RMS digital multimetry, and real-time data logging into a single field-service instrument. Built for electronic troubleshooting and general-purpose testing, it delivers 40 MHz bandwidth with real-time sampling to 200 MSa/s and equivalent-time sampling to 2.5 GSa/s. The 4.5-inch color LCD (320 × 240) provides clear waveform visualization across all operating modes.
