The SR SER1CH-UA-BANA, SER1CH-UA-DSUB, PAR1CH, PAR4CH, PAR8CH, PAR24B, and DSPA64/HLF data acquisition systems are now legacy products. This designation usually occurs because one or more of the components used on the board has been discontinued by its manufacturer and is no longer available. The PAR4CH has been replaced by the USB4CH data acquisition system and the PAR8CH and PAR24B have been replaced by the USB8CH data acquisition system. Regrettably, we do not have any replacements available for the DSPA64/HLF at this time. However, we are considering designing one in the future, so we would be interested in hearing what features in the DSPA64/HLF you find important. You can reach us at: info@symres.com

Product Description

The PAR1CH is the 1 channel member of the PARxCH family of 24 bit realtime continuous data acquisition systems. It offers a low cost way to begin using 24 bit technology with all the capabilities of the 4 and 8 channel systems.

For the PAR1CH 24 bit A/D, highest resolution occurs at 10-1000 Hz, with maximum sampling rates of 5 kHz sustained. The PAR1CH analog input is differential with an amplitude range of +/- 10 volts. The on board 2 Mb DRAM allows continuous no loss data acquisition even on heavily interrupted and multitasking PCs. The PAR1CH sits outside the PC for improved noise performance and communicates its acquired data using the standard PC parallel port.

A full-featured acquisition and display program is included with the system software, so you can be up and running immediately; controlling acquisition rates and continuously saving acquired data to disk. For developing custom applications, low level functions that control the PAR1CH are supplied as static, DLL or shared libraries. Full source code is included and the PDF user manual contains circuit diagrams.

The 2 MB DRAM data buffer acts as a back up to make sure data is not lost even if the PC is interrupted for long periods on other tasks. There are no "fall through" times or buffer latencies. As soon as any data is ready from the PAR1CH, the PC is notified so it can get the data. Any additional data that comes in while the PC is getting around to servicing the PAR1CH is simply stored up. With 2 MB of buffering at 10 Hz sampling, you have more than 4 hours of back up, with proportionally shorter times at higher frequencies. These times are more than enough to satisfy typical PC latencies.

The PAR1CH comes with all the accessories you need to start acquiring data. These include software, manual (PDF), 9 VDC power supply, 6' parallel port cable, TRM15E 4 channel terminal board, and desktop enclosure.

Product Description

The PAR8CH is the 8 channel member of a family of 24 bit realtime continuous data acquisition systems with an individual A/D per channel architecture. 1 and 4 channel units are also available.

For the PAR8CH 24 bit A/D, highest resolution occurs at 10-1000 Hz, with maximum sampling rates of 5 kHz sustained. All PAR8CH inputs are differential with amplitude ranges of +/- 10 volts. The on board 2 MB DRAMs allow continuous no loss data acquisition even on heavily interrupted and multitasking PCs. The PAR8CH sits outside the PC for improved noise performance and communicates its acquired data using the standard PC parallel port.

Several features beyond those shared with the 1 and 4 channel PARxCH products are standard on the PAR8CH including improved digital I/O and GPS time stamping. While all three PARxCH can poll the digital inputs, the PAR8CH automatically samples the digital inputs each time a new analog data point is ready and includes the digital data in the regular data stream. The PAR8CH also has an 800 ns onboard counter that can be used in place of the PC's high speed counter when time stamping data with the PARGPS. This enhances accuracy since variation in PC interrupt latencies no longer influences the timing calculation.

For all the PARxCH products, a full-featured acquisition and display program is included with the system software, so you can be up and running immediately; controlling acquisition rates and continuously saving acquired data to disk. For developing custom applications, low level functions that control the PAR8CH are supplied as static, DLL or shared libraries. Full source code is included and the PDF user manual contains circuit diagrams.

The pair of 2 MB DRAM data buffers act as a back up to make sure data is not lost even if the PC is interrupted for long periods on other tasks. There are no "fall through" times or buffer latencies. As soon as any data is ready from the PAR8CH, the PC is notified so it can get the data. Any additional data that comes in while the PC is getting around to servicing the PAR8CH is simply stored up. With 4 MB of buffering at 10 Hz sampling, you have more than 4 hours of back up, with proportionally shorter times at higher frequencies.

PAR24B -- click for tour

Product Description

The PAR24B is an 8 channel, 24 bit realtime continuous data acquisition system with an individual A/D per channel architecture. With an individual A/D per channel you get high resolution on each channel with no channel to channel timing skew or crosstalk.

For the PAR24B 24 bit A/D, highest resolution is in the 10-100 Hz range, with maximum sampling rates of 1 kHz. All PAR24B inputs are differential with amplitude ranges jumper selectable for +/-2.5 or +/- 10 volts. The on board SRAM FIFO allows heavily interrupted and multitasking PCs to finish any current processing before retrieving acquired data, resulting in continuous acquisition with no data loss. Sitting outside the PC for improved noise performance, the PAR24B communicates all of its acquired data to the PC using the standard EPP/BPP parallel port.

A full-featured acquisition kernel and display program is included with this system so you can be up and running immediately. This program allows users to control acquisition rates and continuously save acquired data to disk. In addition, for those wishing to develop their own custom code and applications, low level functions for controlling the PAR24B are supplied as 16 and 32 bit DLLs and as National Instruments LabVIEW drivers. Full source code is included. Also, the PDF user manual contains circuit diagrams for hardware specifics.

The PAR24B comes with all the accessories you need to start acquiring data. These include software, manual (PDF), a 4K FIFO, 9VAC power supply, 6' parallel port cable, an 8 channel terminal board, and a desktop enclosure.

DSPA64/HLF 64 Ch 16 Bit A/D with DSP -- click for tour

Product Description

The DSPA64/HLF combines an A/D converter board and a DSP coprocessor board to make a complete system for realtime continuous A/D acquisition and processing. The DSPA64 features a high resolution 16 bit A/D converter and a 64 channel programmable multiplexer array.

Sampling at aggregate rates up to 138 kHz, all DSPA64 inputs are differential and buffered through a low noise precision instrumentation amplifier. In addition, overall gain and amplitude limits can be user set by resistors, with nominal values of +/-2.75 or +/-10.00 volts. The DSPA64 sits outside the PC and uses a 16 conductor ribbon cable to communicate all of its acquired data in serial digital format to the DSPHLF card installed in an ISA slot inside the PC.

Featuring a powerful 50 MHz Agere DSP32C floating point DSP processor, the DSPHLF card processes and buffers up to 1Mb of incoming DSPA64 data without any required PC time. Furthermore, double buffering provided by the DSP32C enables large blocks of data to continuously be saved to the hard disk. Data acquisition continues uninterrupted with no data loss while saving to disk. Because the PC is completing only disk saves, PC time is available for displaying graphics or running a windowed environment.

Incoming data is processed up front by the DSP32C, enabling the user to apply digital filters to the incoming data in real time. For example, data can be over sampled and then smoothed to increase the effective resolution of the overall system. This powerful feature is further enhanced because DSPHLF programs are saved in the on board SRAM memory, and can be changed at any time by the user. This allows for modifying filtering coefficients and other parameters as necessary in real time.

A full-featured acquisition kernel and display program is included with this system so you can be up and running immediately. This program allows users to specify selected channels, control acquisition rates and continuously save acquired data to disk. In addition, for those wishing to develop their own custom code and applications many tools are provided. These include an assembler and monitor debugger for the DSPHLF and low level functions for controlling the DSPA64 supplied as 16 and 32 bit DLLs and as National Instruments LabVIEW drivers. Many example programs, both Windows executables like Scope and LabVIEW VIs, are provided. Full source code is included. Also, the PDF user manual contains circuit diagrams for hardware specifics.

The DSPA64/HLF comes with all the accessories you need to start acquiring data. These include software, manual (PDF), triple output power supply, 7' ribbon cable, test leads, one 8 channel terminal board. A separately priced rack mount enclosure is also available.
