The Yokogawa DL7100 is a 4-channel digital oscilloscope built for precision waveform capture and analysis in demanding measurement environments. Operating at 500 MHz analog bandwidth with 1 GS/s maximum sampling rate per channel, it delivers 8-bit vertical resolution across a 2 mV/div to 10 V/div sensitivity range. An optional 16-bit logic input channel extends monitoring capability to mixed-signal applications, while configurable record lengths up to 8 MS/s per channel support extended acquisition windows without data compromise.
