Keithley KPCI-3110 1.25MHz, 12-Bit High Speed Multifunction Board

The Keithley KPCI-3110 1.25MHz, 12-Bit High Speed Multifunction Board is the perfect solution for demanding measurements, offering a combination of speed, resolution, high channel count, and quality that few other boards can match. Whether you are developing a new product or simply trying to understand and interpret physical phenomena, the KPCI-3110 provides the capability you need.

The multifunction KPCI-3110 board combines high speed analog inputs and analog outputs. This data acquisition board provides input speeds of up to 1.25MHz and output speeds of up to 500kS/s. The KPCI-3110 also features 16 digital I/O lines and four counter/timers. In addition, this PCI-bus board includes 32-bit DriverLINX software drivers, TestPoint drivers, and LabVIEW VIs.

The KPCI-3110's high speed analog inputs enable the user to sample data at speeds up to 1.25MS/s. Some typical high speed applications include high speed data acquisition and statistical sampling, testing of electrical components and sub-assemblies, continuous process monitoring, and industrial control and automation.

The KPCI-3110 data acquisition board is ideally suited to any application requiring accurate, high speed measurement of analog inputs. The analog inputs are software configurable for single-ended or differential inputs and bipolar or unipolar input ranges. An Amp Low connection allows single-ended inputs to be referenced to a common point other than ground to provide 32 pseudo-differential inputs.

For added flexibility, a 1024-location channel-gain queue allows you to sample non-sequential chan- nels and channels with different gains.

The Calibration utility allows both manual and automatic software calibrations.

The KPCI-3110 can acquire a single value from any channel or a number of samples from multiple channels. To acquire data from multiple channels, the KPCI-3110 board provides two scan modes: continuously paced and triggered. Both scan modes can be paced using an internal or an external clock.

The Continuously Paced mode allows a board to continuously scan the channel-gain queue and acquire data until stopped or until a specific number of samples are acquired. The Triggered Scan mode allows a board to scan the channel-gain queue at high speeds with a programmed interval between scans, emulating a simultaneous sample-and-hold operation. Use an external trigger or an internal clock to re-trigger a Triggered Scan operation to cycle through the channel-gain queue up to 256 times per trigger. This allows the acquisition of a waveform of data per channel for each trigger (up to 256k samples per trigger).

The KPCI-3110 provides several triggering modes, including pre-trigger, post-trigger, and about-trig- ger modes. The trigger source can be an analog or digital signal. The level of the analog trigger can be from -10V to +10V. Pre-trigger mode allows acquisition to occur until an external trigger occurs. Post-trigger is the standard acquisition mode; acquisition begins after an internal or external trigger event and continues until an end condition occurs or the specified number of samples are collected. About-trigger mode allows acquisition to occur both before and after an external trigger.

Use an internal or an external clock to pace the analog inputs. The internal clock can be set to acquire data from one or more channels from 1S/s up to 1.25MS/s. To acquire data at slower rates, use an external source, or cascade two or more of the counter/timers and connect the output to the external clock input. The external A/D sample clock and the digital trigger input signals are accessible through the connector.

The KPCI-3110 features two 12-bit analog output channels with an output range of +10V. The analog outputs can be used concurrently with the analog inputs to perform gap-free simultaneous stimulus and response. The analog outputs can be triggered synchronously with, or independently of, the ana- log inputs using the analog threshold trigger or the dedicated digital trigger input. An internal or external source clocks the analog outputs. The analog outputs can be updated simultaneously at a rate of up to 500kS/s each (system dependent), and are set to 0V at power-up.

The on-board FIFO can contain from two to 4096 waveforms samples with update rates at a guaranteed 500kS/s. Repetitive waveforms can be loaded into the on-board FIFO, and the data in this FIFO can be continuously cycled through.

This board features 16 digital I/O lines that can be programmed into two banks of eight lines for input or output. The status of the digital inputs can be read at high speeds by including the digital input lines as a channel in the analog channel-gain queue. This dynamic digital input feature time stamps the digital inputs in relation to the analog inputs. In this mode, all digital input lines are read as one word. The dig- ital outputs can drive external solid-state relay modules with its 12mA sink and 15mA source. These boards also supply two auxiliary digital outputs. These digital outputs change state when a specified analog input is read, providing a triggering source or a synchronization source for external circuitry or other data acquisition boards.

These boards provide four 16-bit counter/timers for use in many purposes, including: counting events, creating a one-shot or frequency output, and measuring frequency input. They can also be used to set the duty cycle, frequency, and output polarity of the output pulse.

These counter/timers can be cascaded. Cascade two counter/timers internally through software. Cascade three or four counter/timers externally on a screw terminal accessory.

The analog input and output connections are made with a 50-pin connector. The digital input and output connections are made with a 68-pin connector
