Yokogawa DLM4058 500MHz Mixed Signal Oscilloscope

The Yokogawa DLM4058 is a mixed-signal oscilloscope designed for embedded systems, power electronics, mechatronics, and automotive testing. It delivers 500 MHz bandwidth across 8 analog channels with a maximum sample rate of 2.5 GS/s and record lengths up to 125 Mega Points. The eighth channel provides Flex MSO capability, functioning as an 8-bit logic analyzer with optional expansion to 24 bits via external logic inputs.

A 12.1-inch XGA TFT display (1024 × 768) enables detailed signal visualization with an ergonomic landscape interface.
