Yokogawa launches mixed-signal oscilloscopes

The Yokogawa DLM2000 Series is a range of mixed-signal oscilloscopes (MSOs) that offer up to 500MHz bandwidth and 2.5GS/s sampling speed.

The oscilloscopes have a long memory of up to 125 M points and an update rate of up to 450,000 waveforms per second.

The DLM2000 Series features a number of measurement and analysis features, including histogram and trending functions, up to 20,000 history memories, digital filtering, zoom windows, user-defined mathematics and serial bus analysis.

The Series consists of six models: three with two channels and three with four, each covering the bandwidths 200, 350 and 500MHz, respectively.

Mixed-signal oscilloscope operation is enabled on the four-channel models by converting the fourth channel of analogue input to 8-bit logic, so that the instrument then functions as a three-channel analogue plus 8-bit logic MSO.

A high-resolution mode (up to 12-bit) is also available.

This logic capability is complemented by the availability of new logic probes with individual bit-threshold setting and 100 kilohm input impedance at 250MHz.

The instruments feature a large (8.4in, 21.3cm) high-resolution (XGA) display in a portrait format package that occupies the size of a single A4 sheet of paper on the benchtop.

The display is enhanced by a fine grid, high luminance and viewing angle, and on-screen markers with simultaneous display of cursors and automatic parameters.

Other features include backlit buttons, additional knobs and jog shuttle, on-screen information in English, German, French, Italian and Spanish languages, two zoom windows with 80:20 or 50:50 zoom/main area split, and a choice of first cycle or screen average mode for frequency measurement.

The combination of long memory and the history function, along with trigger and search capabilities, means that the chances of missing elusive or intermittent waveforms are minimised.

Using the M2 option, up to 125 M points of storage capacity is available, allowing, for example, 10kHz signals to be recorded for up to 5,000 seconds.

Even at a sampling rate of 1.25GS/s, waveforms down to 0.1 seconds can be captured.

With the history function, up to 20,000 previously captured waveforms can be saved in the acquisition memory.

Any one, or all waveforms, can be displayed on screen with the ability to carry out cursor measurements and other analysis operations including FFT analysis and user-defined maths.

Waveforms can be displayed one at a time, in order, with automatic play back, pause, fast forward or rewind functions.

The DLM2000 Series comes with a variety of configurable triggers combining analogue and logic inputs such as edge, enhanced and B-triggers.

These include dedicated trigger functions for Can, Lin, Uart, I2C and SPI serial bus patterns as well as the ability to perform simultaneous analyses on two different buses operating at different speeds.

This capability is enhanced by search facilities, allowing the user to look for specific data in the long memory.

The four-channel models in the DLM2000 Series are also able to import the Can DBC database and either trigger, or decode, a physical value.
