Analogic DBS8700 / DBS8701 8-Port High Precision Digitizer

  • 16-Bit Resolution and Accuracy
  • On-Board Sequencer
  • 8 Differential Inputs
  • Dynamically Set Gain per Channel
  • Variable Sampling Rate
  • Multiple Sample Clock Sources
  • Versatile Trigger Unit


The Analogic DBS 8700/8701 features the first 200 kHz/400 kHz, high resolution, multi-channel Digitizing Systems that combine the superior precision of 16-bit measurement with high throughput in a “C” size VXI module. Fully compatible with VXI specification Rev. 1.3, a DBS 8700/8701 occupies a single slot in a “C” size VXI chassis and provides an unparalleled price/performance ratio when used alone or in combination with other VXI modules (multiplexers, or digital-to-analog converters) within the Analogic DBS 8700/8701 series. Reflecting the many years of Analogic experience in precision instrumentation, a DBS 8700/8701 is designed to meet the stringent demands of fast and accurate measurements associated with multichannel applications such as vibration analysis, the testing of rotating machinery, and automotive and jet engine testing, as well as the analysis of large mechanical structures and other complex mechanisms.

Eight shielded, differential inputs are provided with both voltage and current protection. The unit is directly expandable to 256 channels with the Analogic family of DBS multiplexer modules. Input signals are multiplexed via an instrumentation amplifier and a programmable gain amplifier, with four software selectable gains, into an ultrafast, high resolution, sampling analog-to-digital converter. The acquisition time, hold-mode settling time and droop rate ensure 16-bit system performance up to the maximum sampling rate.

The DBS 8700/8701 provides a powerful 2-channel, on-board DMA controller as a standard feature. The DMA controller executes fast transfers over the VMEbus (P1) sending data directly into the system’s memory, significantly enhancing total system performance by dramatically reducing the I/O overhead of the bus.

Three flexible trigger sources are available: a user-supplied outside trigger, an internal trigger derived from a precision clock residing on the module, and a data dependent trigger produced by the occurrence of a specified event on a selected channel. Before beginning the data acquisition, trigger information, as well as channel selection inside a scan, and gain setting are downloaded into the timing and control unit resident on the DBS 8700/8701 module. For ease of integration, a selection of available software drivers is offered for use with the card. No coding is required by the user; all necessary commands are included in the driver.

Product Family: DBS8700, DBS 8700, DBS-8700

InstraView™ Equipment Inspection

Buying used equipment doesn't always have to be a shot in the dark. We know there are plenty of differences when it comes to used equipment and quite often, choosing between different pieces is difficult, especially when the equipment is not sitting right in front of you.

Well, what if you were able to see a piece of equipment before you purchased it? Not just a picture from the manufacturer's website, but the actual piece of equipment you would receive.
With InstraView™, we move you one step closer to inspecting the equipment you're interested in without having to wait for the equipment to show up at your door.

InstraView™ works in your web browser and allows you to view the actual piece of equipment you're interested in before purchasing. You can zoom in close to see the labels with the serial number or zoom out to see the overall condition of the equipment.

It's like having the store come to you!
