The Yokogawa DLM3032 is a 350 MHz mixed-signal oscilloscope that combines digital oscilloscope and logic analyzer functionality into a single instrument. It acquires and displays both analog and digital signals simultaneously, making it ideal for characterizing complex electronic systems. The 8.4-inch XGA TFT color display (1024 × 768 pixels) provides clear waveform visualization across dual analog channels.
