PXI Card, Time Interval Counter, 225 MHz - 2 GHz | GTX2200 Series

GTX2200 Series – PXI/PXIe frequency counter with 2× BNC (50 Ω/1 MΩ, AC/DC), 100 ps time resolution, up to 2,300 meas/s, 10 MHz reference input, and up to 2.0 GHz

Performance Meets Precision – At a Glance
The GTX2200 Series brings high-end frequency measurement directly into your PXI or PXIe system. Whether in a classic PXI chassis or a modern PXI Express enclosure, the modules integrate seamlessly and deliver reliable performance for demanding test tasks. Optionally combinable with a PXI Embedded Controller. As a PXI card / interface card, integration into existing PXI racks and available slots is straightforward; PCI card / PCIe card variants as well as PCI extension are also supported.

Plug. Connect. Measure.
Integrated software tools keep everything in view: displays, measurements, and firmware management are centrally organized – for a smooth setup and fast results. Relevant data and information are available immediately for comparison; optional add-ons simplify initial setup.

Engineered for Efficiency and Repeatability
The high-throughput architecture of the GTX2200 Series ensures stable, reproducible measurement data – whether in the lab, in development, or in automated test operations. Designed for modern metrology, high numbers of measurement cycles, and precise counter functions on PXI Express backplanes (PCIe).

Versatile in Use – precise down to the Details
Whether time, frequency, or pulse-width measurement: the counters of the GTX2200 Series excel in clock analysis, RF validation, and complex radar and communications projects. An embedded controller boosts performance in PXIe environments and enables reliable capture of short pulses; robust power reserves support long-duration tests. As a result, the series serves as a precise frequency counter and interval counter in PXI/PXIe racks.

Future-Proof Scalability
With three model variants, the GTX2200 Series offers the right performance class for any application. The platform supports sequential measurements based on arbitrary waveforms and allows integration of an arbitrary waveform function generator. Expansions can be integrated into existing enclosures with ease – for maximum scalability.
