Yokogawa DLM2022 200MHz Mixed Signal Oscilloscope

The Yokogawa DLM2022 is a 200 MHz mixed signal oscilloscope designed for electronic design, debugging, and general-purpose testing. This two-channel instrument combines digital oscilloscope capabilities with configurable mixed-signal analysis, supporting simultaneous observation of analog and digital signals. The DLM2022 delivers up to 2.5 GS/s sampling with deep memory architecture - standard 62.5 Mpts expandable to 250 Mpts with optional modules - enabling detailed waveform capture and extended measurement windows.

An 8.4-inch LCD display and compact portrait form factor provide enhanced visibility and benchtop efficiency.
