UF2e-7005 Overview

The UF2e-7005 is used for recording or generating TTL signals at rates to 125 MHz on up to 16 bits. The direction of the bits is set as a group of 16 prior to starting the board and can only be changed when the board is stopped. This makes the board unsuitable for handshaking applications.

The board has a unique capability to operate with 1, 2, 4, 8 or 16 active bits. This coupled with the unique memory saving mode can eliminate the need to buy additional card memory and also allow the user to record or generate much longer signals. The UF2e-7005 achieves this be reallocating the complete board memory to only the active bits. Other manufacturers board allocate the memory behind each bit, so un-used bits waste expensive memory.

The table below shows how a standard UF2e-7005 with 256 MB or 4GB of onboard memory uniquely allocates all of the available board memory to the active channels. Other memory options are available, the examples are chosen for illustration:

Advantage of PCI Express for instrumentation

Read an application note on the advantages of PCI Express here.

Standard mode...

The signals are downloaded to the onboard signal memory. Output is started on software or external TTL trigger and the signal(s) are output once, n times, or repeated until the card is stopped by software. This mode allows the cards to output at the maximum clock rate. While generating, the card operates independently of the host PC so the cpu can be used for other tasks.

... and FIFO mode. Recording or Generating continuously at 120 MBytes/s

Alternatively, the UF2e boards also provide a FIFO mode that continuously transfers the waveform data gap-free to or from the PC. This mode has the advantage that longer signals can be recorded or generated than the available on-board memory.

Note that the maximum output rate is limited by the PCI Express bus transfer rate, which is typically 120 MBytes/s, and the number of activated channels. For a 16-bit Digital board this equates to a max sampling rate of f=120M/2/n where n is the total number of activated channels (including all cards in the system).

Synchronizing multiple-cards in a single PC

The Star Hub option is an add-on that allows multiple cards, even of different types, to be synchronized. There are two versions that support up to 5 cards or 16 cards.

The Star Hub 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. Please note that the UF2e Star Hub option is not compatible with the older UF Star Hub option.

Synchronizing multiple PC's

A new option, the System Star Hub synchronizes up to 271 UF2e and UF2 cards cards hosted in up to 17 PC's. This option is useful if:

  • The number of channels/cards required can't fit in one PC
  • Data will be stored continuously (using FIFO mode) to hard disk array and the limits of the PCI/PCI Express means not all cards can be placed in one system
  • Extensive online calculations have to be made for several channels and the bus bandwidth isn't capable of streaming data for all channels or a single cpu power is not sufficient
Fine Resolution Sampling Rates

Most other products limit you to a few fixed sampling rate choices, however with the UF2e 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.

External Clock and External Trigger

Need to synchronize with external equipment? As standard the UF2e 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.

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 UF2e Digitizer, AWG and Digital cards to reduce programming times.
