MF16080 USB Data Acquisition System

• 16 analog inputs with 12 bit resolution at 100kHz sum sample rate
  
  
• Single-ended or differential inputs
  
  
• 8 analog output channels using 8 seperate DACs with 12 bit resolution
  
  
• 10 digital I/O ports
  
  
• Available in extended temperature range -40°C .. +105°C (-40F .. +220F)
  
  

• Low power design - USB bus powered
  
  
• Aluminum enclosure: lightweight, excellent shielding, maximum stability and durability - even under extreme thermal conditions of >100°C!
  
  
• Standard connectors: Mini USB connector for USB,  37 pole DSUB connector for analog I/O and ports. No proprietary cables and connectors needed!
  
  
• 5V sensor power supply
  
  
• Available in 5 versions:
• MF16084: 4V  / +-2V
• MF16081: 10V / +-5V
• MF16082: 24V / +-12V maximum input voltage
• MF16084-MA: 20mA current inputs
• MF16080: custom made versions
• Signal conditioning with channel-seperated low or high pass filters.
• Combinations of input voltage ranges, i.e. 8 x 20mA, 8 x 4V
• All parts are integrated into the card
  
  
• Nearly simultaneous sampling: design guarantees a small and constant delay between adjacent channels during a multichannel data capture, even though only one ADC is used. This results in constant phase delays between signals regardless of the sample rate.
  
  
• Operating systems Windows® 98/Me, Windows® 2000, Windows® XP, Windows® Vista^TM.
  
  
• Programming language support (see PCDAQ Driver for detailed information):
  
  • Microsoft® Visual C++®
  • Microsoft® Visual Basic®
  • Microsoft® .NET / Visual C#
    
  • Agilent VEE
  • Borland Delphi
  • National Instruments LabVIEW
  • TransEra HTBasic

• Custom input configuration: You need a special input voltage range? Lowpass or highpass filter? We can tailor the card to your needs, for your measurement system remains compact. .
  
• System capability: The card can be equipped with an expansion port for daisy-chaining multiple cards. In contrast to plugging multiple devices into USB ports, the timing between the cards stays fixed and well-defined. Up to 4 cards can be connected to act like one card with a maximum of 64 analog inputs, 32 analog outputs and 40 digital I/O ports. All cards need to use only one USB connection.

The PCDAQ Driver that has been well-known for years in the PCMCIA card range supports the MF16080 as well. It provides the driver and the Online manual in PDF and HTML formats.

It supports application development using Microsoft® Visual C++®, Microsoft® Visual Basic®, Agilent VEE, Borland Delphi, National Instruments LabVIEW and TransEra HTBasic. The programming interface is retained from the PCMCIA card range – no surprises in programming the card.

Design details

The card internally uses a high speed SPI bus for connecting the different parts of the data acquisition system together.

The analog input signals are scaled down to the ADCs native voltage range.  The ADC has an internal FIFO allowing to execute a complete scan on its own. The accuracy of a measurement is enhanced by an on-board temperature sensor with 1/8 K resolution.

Data is then transferred into the Controller's FIFO buffer, finally via USB at high priority into a huge FIFO buffer inside the PCDAQ Driver. This FIFO is designed not to loose data even if the application is not capable of reading data for a few seconds. Readings are scaled if necessary and then transferred to the application.

Analog output signals are generated by eight seperate DACs. Due to the high accuracy they are well suited to create output signals as well as sensor supply voltages. This makes the card well suited for closed loop applications.

The MF16080/16084 cards include a low power reference voltage source for obtaining reproducable measurements - for ADC and DACs.

The digital I/O ports provide TTL/CMOS compatible inputs. The outputs operate at TTL levels.  6 ports can source up to 4mA. The other 4 outputs can source up to 15mA.  This enables them to supply LEDs directly, to directly connect to reed relais and to other devices requiring higher operation currents.
