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.

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.

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: 

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). 

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.

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.

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. 

   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

Example: Parts Durability Testing

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

You can display all past waveforms, and view a list of acquisition times at min 1µs resolution

• Edge: Trigger on a single trigger source condition (rising, falling, rising/falling)
• Time: Trigger at a specified time or fixed interval

Enchanced

• A -> B(N): Trigger when condition B is true N times after condition A becomes true
• A Delay B: After condition A becomes true, trigger the first time condition B becomes true after a set time has passed
• Edge On A: Trigger on an OR condition of an edge trigger while the A trigger is true.
• OR: Trigger if at least one trigger condition of multiple trigger sources is true
• AND: Trigger if all trigger conditions of multiple trigger sources are true
• Period: Trigger when a condition regarding the waveform period becomes true
• Pulse Width: Trigger on a condition relating a pulse width condition being true with a specified time width condition.
• Wave Window: Trigger when the signal passes outside of an real time template "Wave Window"

Excellent noise rejection performance is achieved through meticulous low-noise design. Floating voltage switching waveforms in inverter circuits can also be captured with precision.
