HIGH LEVEL DIGITIZING SYSTEM

Antiquated computers and storage media, along with dated software, limits data acquisition system performance at many test facilities. While transducers and signal conditioning can last for decades, the rapid advance in computer technology means that computers and software are obsolete in a few years. Most systems can be updated without replacing the signal conditioning. The 6016 and 6028 are high-level digitizers for the Series 6000 Data Acquisition System and are supported by PI660 software that can replace aging computers and software, while retaining the existing signal conditioning.

The 6028 and 6016 are 8 and 32-channel 16-bit digitizer cards. Both digitize at programmable rates. The 6028 is for high-speed channels with rates up to 100 kS/s per channel. The 6016 is for lower-speed channels with rates up to 5 kS/s per channel. When installed in the 6000 system with USB 2.0 interface, aggregate rates up to 8 MS/s are possible.

PI660 Software runs on Windows XP. This low-cost platform has many benefits that include massive storage, high processing speed, network connectivity and data distribution to multiple workstations. The 6000 offers many add on features like digital I/O, IRIG time stamping, digital signal processing for derived parameters, alarms and PID control outputs just to name a few. It offers many modern signal conditioning choices like 300 Volt common mode, continuously programmable filters, 100 kHz analog bandwidth and charge amplifiers.

CALIBRATION FOR HIGHEST ACCURACY MEASUREMENTS

Pacific Instruments calibrates and aligns each I/O module it manufactures, using NIST traceable test equipment prior to delivery. All critical performance specifications for each channel on the I/O module are verified and recorded. When the module is certified by Pacific, it meets all of its performance specifications.

Users typically perform periodic calibrations during the life cycle of any I/O module. Depending on the application and facility requirements this can range from annual calibration and certification to frequent verification of critical parameters such as gain accuracy and stability. Pacific provides support for both periodic and frequent calibration. The ACS2000 calibration system may be used to automatically perform all critical performance tests channel by channel. It is the same system used by Pacific during factory I/O module calibration and certification. For frequent calibration (typically performed before a test) software provides gain and zero calibration and linearity verification using voltage substitution and a NIST traceable voltage standard. Any gain or zero errors detected can be automatically eliminated during data acquisition, providing typical accuracies of +/-0.02%.
