Yokogawa has introduced the DLM2000 Series mixed-signal oscilloscopes (MSOs), with up to 500 MHz bandwidth and 2.5 GS/s sampling speed.
They have a memory of up to 125 M points and an update rate of up to 450,000 waveforms per second.
The oscilloscopes have flexible analogue and digital inputs and a large-screen display in a compact ergonomic body.
The DLM2000 Series features 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 500 MHz, respectively.
Converting the fourth channel of analogue input to 8-bit logic enables the instrument to function as a three-channel analogue plus 8-bit logic mixed-signal oscilloscope.
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 an 8.4in high-resolution (XGA) display in a compact portrait format package that occupies an area the size of an A4 sheet of paper.
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, 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 long memory and history function and trigger and search capabilities minimise the chances of missing elusive or intermittent waveforms.
Up to 125 M points of storage capacity is available when using the /M2 option, allowing, for example, 10kHz signals to be recorded for up to 5000 seconds.
Even at a sampling rate of 1.25 GS/s, waveforms down to 0.1 sec can be captured.
With the history function, up to 20,000 previously captured waveforms can be saved in the acquisition memory and any one or all of them can be displayed on screen with the ability to carry out cursor measurements and other analysis operations including FFT analysis and comprehensive user-defined maths.
Waveforms can be displayed one at a time, in order, or automatically played back, paused, fast-forwarded or rewound.
The DLM2000 Series comes with a variety of easy-to-configure 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 the extensive search facilities, allowing the user to look for specific data in the long memory.
The four-channel models in the DLM2000 Series can import the CAN DBC database and either trigger on, or decode, a physical value.
