YOKOGAWA DLM2000 Mixed Signal Oscilloscope.


The Yokogawa DLM2000 is a bench-top oscilloscope for electronic design or debug.  It’s ergonomic and easy to use, and packed with features.  With bandwidths from 200, 350 & 500 MHz and memory from up to 250 Mpoints, you can be certain there is a DLM2000 to meet your application requirements.

With the Yokogawa DLM2000’s industry first “flexible MSO input”, you can choose to activate channel four as an analogue input, or use it to acquire 8 bits of logic instead. Modern electronics include analogue and digital circuitry—and the DLM2000’s flexible MSO input lets you measure both, including mixed signal triggers and decoding of parallel or serial bit patterns.

  • Large 8.4 inch LCD colour display.
  • Lineup includes 200MHz, 350MHz and 500MHz bandwidth models.
  • Lightweight and compact.

Capture and Display Zoom and Search Functions
Real time Filter with optimum noise reduction supports a wide range of frequencies (from 8kHz to 200MHz). The Yokogawa DLM2000 series has two types of filters, one processed at the input circuit and one based on MATH functions. These filters are effective for rejecting unwanted signals allowing observation of only the desired bandwidths.

Real Time Filters
Each channel has 14 low pass filters available from 8kHz to 200MHz Waveforms of limited bandwidths are stored in internal memory.

Zoom into different Points – Waveform Zoom and Search Functions
Zoom two locations simultaneously. Because the Yokogawa DLM2000 series lets you set zoom factors independently, you can display two zoomed waveforms with different time axis scales at the same time.

Also, using the Auto Scroll function, you can automatically scroll waveforms captured in long memory and change the zoomed location. With Auto Scroll you can choose forward, backward, fast-forward, scroll speed, and other control options.

Two types of Waveform Searching
Normally, searching for data takes time, and long memory is useless without functions for extracting desired data from a large capacity memory. That’s why the Yokogawa DLM2000 series does not simply offer long memory, it also provides powerful waveform search functions.

Searching for data in a single screen: The Zoom Search function. This function searches captured waveforms in the long memory and displays waveforms that meet the search criteria in the zoom area. The locations of the found waveforms are marked on the screen.

Measure Function and Statistics
Twenty-eight waveform parameters are included such as: maximum, minimum, peak-to-peak, pulse width, period, frequency, rise/fall time, and duty ratio.

Automated measurement can be performed using up to 20 of these waveform parameters. Also, waveform parameters can be measured repeatedly, and the statistical values displayed (mean, maximum, minimum, standard deviation etc).

Trend and Histogram Displays
Waveform parameters such as period, pulse width, and amplitude can be measured repeatedly and displayed in graphs. In a single screen you can observe period-by-period fluctuations, complete amplitudes every screen using multiple waveforms, and display histograms referencing the voltage or time axis using values from repeated automated measurement of waveform parameters.

Measure Voltage/Time differences automatically
Cursors can be placed on the displayed waveform from signal data, and various measurement values at the intersection of the cursor and waveform can be displayed. There are six types of cursor, ΔT, ΔV, ΔT and ΔV, Marker, Degree Cursor.

Analyze Frequency Spectrums
Up to two FFT analysis can be performed simultaneously. FFT can be performed on computed waveforms in addition to the actual waveforms on CH1 to CH4. Analysis can be performed on the frequency components of waveforms filtered for limited bandwidth, on frequency for changes in period of rotary objects, and other phenomena.

Keep Waveforms with a Single one Button Push
By pressing the SNAPSHOT key to the lower right of the screen, you can freeze a white trace of the currently displayed waveform on the screen. You can press the key repeatedly and conveniently leave traces for comparing multiple waveforms. Also, snapshot data recorded on screen can be saved or loaded as files, and can be recalled for use or reference waveforms when making comparisons.
