The Yokogawa DL350 Portable ScopeCorder is a battery-operable instrument that combines long-memory digital oscilloscope and data logger functionality in one compact unit. Field-deployable and lab-capable, it captures transient signals and records long-term data across voltage, current, power, temperature, vibration, strain, frequency, logic, and serial bus measurements. Its modular architecture supports up to 32 analog channels plus 16 digital/logic channels through interchangeable input modules, with configurable isolated and scanning inputs. An 8.4-inch resistive touchscreen supports gloved operation and stylus input for intuitive field control.
