The Yokogawa DLM2032 is a 350 MHz mixed signal oscilloscope that combines digital oscilloscope and logic analyzer capabilities in a single instrument. It enables simultaneous observation and analysis of analog and digital signals—up to 3 analog channels plus 8 logic channels for a total of 11 input signals observed concurrently. The instrument excels at embedded system debugging, power electronics evaluation, and general electronic design workflows where both analog transients and digital state information must be captured together.
