The DL850 ScopeCorder Series are modular, waveform recording instruments that can measure voltage, current, strain, acceleration, and other phenomena– simultaneously.

With high speed sampling, high isolation withstand voltage, and multichannel measurements, the DL850 Series offers powerful support in the development, evaluation, and quality control of energy efficient devices.

For increasingly fast inverter signals

High speed (100 MS/s), High resolution (12-bit), 1kV isolated measurements.*

Yokogawa's isoPRO technology offers industry-leading isolation performance at the highest speeds. The isoPRO core technology is designed with energy savings applications in mind. It gives you the performance needed to develop high efficiency inverters, which employ high voltages, large currents, and high operating speeds.

Example – Measuring Inverter Output

17 plug-in modules allow for flexible assorted measurements.

The lineup includes two new module types: A 16-CH Temp./Voltage Input Module, and a CAN & LIN Bus Monitor Module (DL850V only). All DL850 modules can be combined with measurement modules from the DL750 series products:

  • High-speed Voltage
  • High-precision voltage
  • Temperature
  • Acceleration
  • Logic Input
  • 16-CH Temp./Voltage – NEW
  • High Voltage
  • 16-CH Voltage
  • Strain
  • Frequency
  • CAN Monitoring (with the DL850V)
  • CAN & LIN Monitoring (for DL850V only) – NEW

Note: The firmware version 2.00 or later is required when using the 16-CH Temp./Voltage Input Module(720221) and/or CAN&LIN Bus Monitor Module(720241).

Advanced – Even More Measurement Points – Up to 128 CH of voltage input and 128 bits of logic input

The 16-CH Voltage Input Module (scanner type*) can measure at 10 kS/s sample rate even when using all 16 channels. With this module populating all 8 input module slots, the DL850 performs 128-CH voltage measurements.

The Logic Input Module supports everything from TTL levels, to high voltage contact closures at up to 10 MS/s*. With eight logic modules, the DL850 can monitor and capture 128 bits of logic.

Example: Measuring the startup sequence of a multi-output power source

Power supplies used in home computing electronics have many outputs, and it is necessary to control the sequences from output to output.  With a multichannel module, you are not limited to voltage measurements; a single unit can also measure everything from PC control signals to AC fan operation, individual component temperatures, and slow to high-speed signals.

Catch transients in durability with high-speed sampling – Dual Capture

To visualize long term trends in durability testing and other situations, data is typically acquired at low-speed sample rates. On the other hand, suddenly-occurring transitional phenomena should be captured at high-speed sample rates.

The "Dual Capture" feature resolves these conflicting requirements by recording at two different sampling rates.

  1. DL850 Dual Capture 1

    Zoom Waveform – You can record up to 5,000 phenomena of high speed trigger measurements (up to 100 MS/s) at a record length of 5-500 kPoints while taking trend measurements at up to 100 kS/s.

  2. Event Waveform -Displays the timing at which high speed "sub" waveforms are acquired
  3. Low Speed Main Waveform – Max: 100 kS/s Trend waveform displayed in a low-speed Roll mode
  4. Capture Waveform – Max 100 MS/s Capture transients with high speed trigger measurement

DL850 Chattering 1

Example: Parts Durability Testing

Parts used in automobiles and other transportation vehicles must be highly reliable. The "Dual Capture" function is very effective when performing vibration testing of connectors under varying temperatures.

  • Chattering is accurately captured at high-speed sampling
  • Check the frequency of occurence at low-speed sampling
 

Enhanced capabilities for vehicle design and development such as CAN & LIN Buses monitoring

DL850V 1

The DL850V ScopeCorder Vehicle Edition can display CAN- and/or LIN-protocol communication data as trend waveforms on the display by using the CAN Bus Monitor Module (720240) or CAN & LIN Bus Monitor Module (720241(*1) ). It can also trigger on decoded waveforms. By identifying the correlation between communication data on the vehicle-installed LAN and analog data such as voltage, temperature, and sensor signals or the ECU’s control logic signal, a vehicle’s overall LAN system can be evaluated. Furthermore, with the /DC option, the DL850V can be driven by DC power such as the vehicle’s battery, in addition to ordinary AC power.

(*1): The CAN & LIN Bus Monitor Module (model: 720241) is supported by the main unit firmware ver. 2.00 or later.

Utilization of Vehicle-installed Network Definition Files (CAN DBC, LIN LDF)

Data to be acquired using a bus monitor module (720240 or 720241) can be specified not only in digital code (hexadecimal or numeric), but also loaded from a network definition file (CAN DBC or LIN LDF).

Example of comparison and verification of a measured signal and CAN bus signal
You can trend the physical value of CAN bus data and the corresponding measured waveforms on the same screen at once. For example, an ignition switch ON/OFF signal, a CAN signal corresponding to that command, and an actual signal measured by a pressure sensor, etc. can be displayed and checked on the same screen, to verify the correlation of those signals.

Support for both AC and DC power (/DC option, DL850V only)

  • Low power consumption of 60 – 120 VA (typ.)
  • Low noise

The DL850V Vehicle Edition can be driven by a 12 V DC battery, vehicle’s cigarette lighter, or ordinary AC power. (We provide accessories for DC driving; see the list of accessories at the end of the catalog.)
