The Yokogawa DL1720 is a 2-channel digital oscilloscope with 500 MHz bandwidth designed for precision signal analysis, circuit validation, and equipment troubleshooting. It delivers real-time sampling with up to 1 MW record length per channel and 8-bit vertical resolution. The instrument combines analog signal capture with optional I2C and SPI protocol decoding, enabling mixed-signal analysis in embedded systems, automotive, and industrial applications.
