UC.4600 Series Overview

There are 12 different 16-bit Digitizer 6U size CompactPCI cards in the UC4600 range. Cards are available offering 2, 4 or 8 input channels and choice of maximum A/D sampling rates.

The UC4600 cards are used as lower cost, more flexible and deeper memory alternatives to oscilloscopes and transient recorders. The fast PCI bus gives direct integration with your preferred PC software, while the 100 MBytes/s data transfer delivers faster test times.


Typical applications include ATE, research, communications.

Standard mode...

The signals can be recorded to the onboard signal memory at the maximum A/D sampling rates using Standard mode. At the end of the measurement, the data is off-loaded to the PC using DMA at the maximum PCI 33MHz bus data transfer rate of up to 100 MBytes/s

... and FIFO mode. Record continuously at 100 MSamples to PC!

Alternatively, the UltraFast boards also provide a FIFO mode that continuously transfers recorded data gap-free to the PC during the measurement at up to 200 MBytes/s. This mode has the advantage that more samples can be recorded than the available on-board memory.

Note that the maximum sampling rate is limited by the PCI bus transfer rate, which is typically 100 MBytes/s, and the number of activated channels. For 16-bit A/D boards this equates to a max sampling rate of f=200M/2/n where n is the total number of activated channels (including all cards in the system).

Simultaneous sampling all channels, multiple cards

Each channel on the UltraFast board is equipped with it's own A/D converter for true simultaneous sampling without time-skew (or phase) errors. For larger systems, up to 16 cards can be perfectly synchronized using the Star Hub option. This distributes the clock and trigger signals, so all channels are without time-skew errors and all cards start on the same trigger condition (any channel, any external TTL trigger). Any card can be defined as the clock master or trigger master by software. It's also possible to configure AND/OR trigger conditions (channel or external TTL) across multiple cards.

Independent amplifers to match each channel to the sensor

Each channel has it's own amplifier and dcV offset adjustment. This means you are able to select one of the 8 possible input voltage ranges and adjust the dcV offset to best match the output from your sensor, for every channel.

Fine Resolution Sampling Rates

Most other products limit you to a few fixed sampling rate choices, however with the UltraFast cards you simply instruct the software which rate you require and the driver will automatically adjust the onboard PLL and hardware divider to achieve the closest sampling rate possible. See the Application Note "Sampling Rate Determination"

External Clock and External Trigger

Need to synchronize with external equipment? As standard the UltraFast cards are supplied with connectors for external clock and trigger. Both can be programmed as input or output, so the card can receive a TTL clock or output the internal clock and the trigger connector can receive a TTL trigger event or generate a trigger event from either a software trigger or detected channel trigger.

Flexible Triggering

The UC Digitizer cards offer an exceptional range of trigger possibilities to avoid false triggering:

  • Edge and Level: positive, negative, both edges
  • Window: define high/low levels; entry, exit
  • Re-Arm : define a level that has to be crossed first, avoids triggering on noise
  • Pulse-width: define a time period, trigger must occur inside/outside to be true
  • External TTL: edge, can be used in combination with pulse-width
  • Double edge: can be used with channel or external triggers
  • AND/OR trigger masks: can be used with channel/ external and digital inputs
  • Force trigger: used to start card if trigger not detected after given time
  • Delay trigger: can delay AND/OR masks by up to 64 ksamples
Easy Programming

Only six key functions to define a complete setup. Small DLL or module (Linux) uses few system resources and does not conflict with other programs. On request, we will be pleased to send you the User Manual as a pdf so you can see the many examples.

The API is identical for all UF/UX/UC series A/D D/A and Digital cards to reduce programming times.
