GT668

Computer graphics card with a cooling fan and multiple electronic components.

With a smaller foot-print and much more powerful performance than its previous generation

GT658 (since 1988), GuideTech’s computerbased GT668 CTIA enables a wider range of cutting-edge applications.

With easy expansion and modular capabilities, GuideTech offers a wide range of CTIA solutions in PCI, PCIe PXI, PXIe, GT9000, GT9000R,

GT9000SLR, GT9000P, GT8000-PXI/PXIe,

GT8000SLR-PXI/PXIe Test Platforms.

A true breakthrough in high-speed Time Measurement and test technology, GuideTech’s

GT668PCIe-1 leverages the power of its CTIA continuous time-stamping technology,

eliminating the need for supplemental triggers, pattern markers or clock recovery circuits

GuideTech’s CTIAs enable serial interface pattern verification and full jitter analysis in milliseconds

for fast, automated characterization and high-throughput test on all ATE platforms, including low-cost in-house testers.

GT668 PXI & PXIe cards can be expanded up to 34 Channels Single Ended Input in a single 3U GT8000 PXI and/or PXIe chassis.

Some of the GT668 measurements include Time Interval Error, 1 PPS Monitoring, Jitter measurements, PLL & Clock Jitter, Spread Spectrum Modulation, PLL Lock Time, Frequency, Period, Pulse Width, Skew, Tpd, Rise/Fall Time, and more.

GuideTech’s GT668 has high-accuracy 10MHz OCXO time-base & NIST traceable calibration, enabling high-precision optimal test at lower

cost.
