Keysight (Agilent) TBS2074 70 MHz, 1 GS/s, 20 M Record Length, 4-Channel Digital Storage Oscilloscope

The Keysight (Agilent) TBS2074 is a 4-channel digital storage oscilloscope built for engineers and researchers performing detailed signal analysis and troubleshooting. Operating at 70 MHz bandwidth with 1 GS/s sampling across all channels and 20 Mpts record length, this instrument captures extensive waveform datasets for deep signal characterization. The 9-inch WVGA color display, 8-bit vertical resolution, and intuitive interface support both expert technicians and users new to oscilloscopy. Edge, pulse width, and runt triggering modes provide flexible signal detection. FFT analysis and 32 automated measurements accelerate protocol and frequency-domain analysis. The TekVPI® probe interface delivers broad compatibility with active, differential, and current probes—eliminating manual scaling. LXI-compliant Ethernet, USB 2.0 front and rear ports, and optional Wi-Fi connectivity enable lab integration and remote control. Built-in Scope Intro handbook, HelpEverywhere® on-screen guidance, and TekSmartLab compatibility support educational deployment. Acquisition modes include YT, XY, vectors, and variable/infinite persistence for comprehensive signal observation.
