Feature Details

PCI-bus Mastering Data Transfer

PCI-1712 and PCI-1712L support PCI-Bus mastering DMA for high-speed data transfer

and gap-free analog input and analog output. By setting aside a block of memory in the PC,

PCI-1712 and PCI-1712L perform bus-mastering data transfers without CPU intervention,

setting the CPU free to perform other more urgent tasks such as data analysis and graphic

manipulation. The function allows users to run all I/O functions simultaneously at full

speed without losing data.

Plug & Play Function

PCI-1712 and PCI-1712L are Plug & Play devices, which fully complies with the PCI

Speciﬁcation Rev 2.2. During card installation, there is no need to set any jumpers or DIP

switches. Instead, all bus-related conﬁgurations such as base I/O address and interrupt

are automatically done by the Plug & Play function.

On-board FIFO Memory

PCI-1712 provides an on-board FIFO (First In First Out) memory buffer, storing up to 1K

samples for A/D and 32K for D/A conversion.

Automatic Channel/Gain/SD*/BU* Scanning

PCI-1712 and PCI-1712L feature an automatic channel/Gain/SD/BU scanning circuit.

This circuit controls multiplexer switching during sampling in a way that is much more

efﬁcient than software implementation. Onboard SRAM stores different gain, SD and BU

values for each channel. This combination lets users perform multi-channel high-speed

sampling with different gain, SD and BU values for each channel.

SD: Single-Ended/Differential; BU: Bipolar/Unipolar

Flexible Triggering and Clocking Capabilities

PCI-1712 and PCI-1712L provide ﬂexibility in triggering action, both in the available

trigger modes and trigger events for analog input. You can acquire data using post-trigger,

pre-trigger, delay-trigger and about-trigger modes. The trigger source could be either an

analog or digital signal. The analog trigger could originate from a dedicated input pin.

In fact, you can designate any of the analog input channels as the analog trigger input.

You can set the analog trigger level within a voltage range from zero to A/D FSR. With

the trigger signal being digital, you can pace A/D and D/A conversion using software

interrupt, internal or external clock.

Continuous Analog Output (PCI-1712 only)

PCI-1712 provides two analog output channels. Both can perform continuous waveform

output. The analog output can be up to 500 kS/s for each analog output channel. Or you

can load a cyclic waveform into an on-board FIFO, which will continuously output the

cyclic waveform. The on-board FIFO of the PCI-1712 can store 2 to 32K samples of the

waveform.

On-board Programmable Multifunction Counter/Timer

PCI-1712 and PCI-1712L are equipped with 3 programmable multifunction counter/timers,

which can serve as a pacer trigger for A/D conversion. The counter chip is an 82C54

or equivalent, which incorporates three 16-bit channels on a 10 MHz clock. And then

we enhance the gate and clock input function for more applications, of event counting,

pulse generation, duty cycle frequency generation, one shot, frequency measurement

and pulse width measurement.
