The ZT8440 Series RF/IF Digitizer comes standard with a full featured, on-instrument spectrum analyzer, and is poised to supply the rapidly growing RF market with a world-class testing solution at a competitive price. The ZT8440 is equipped with future-proof technical specifications including:
- Real-time Quadrature Digital Down Converter (DDC) with fractional resampling and decimation
- Vector signal analysis capability of an ultra wide, 160MHz instantaneous bandwidth
- Extremely low noise floor and a high dynamic range
- Fast switching and all-digital frequency hopping
- Real-time highly flexible FPGA processing
The ZT8440 Series leverages ZTEC Instruments' value-add to modular instruments by providing an intuitive GUI, ZSignal™. ZSignal™ provides advanced integration and support with a simple and familiar interface to ease the transition from a bench-top spectrum analyzer to its modular instrument counterpart. ZSignal™ was built in accordance with award-winning ZScope® and ZWave® platforms to minimize the time needed to integrate the instrument into both new and legacy software.
The ZT8440 Series provides a true modular architecture for synthetic instrumentation because it is designed to be interoperable with 3rd party RF modules such as an RF down converter. In addition, the RF/IF digitizer offers bus master control of those RF instruments for speed and deterministic operations.
"ZTEC Instruments is committed to providing our customers with a distinctly lower-cost solution with superior bandwidth, sample rate, dynamic range, and integrated DDC," President Chris Ziomek states. "As we exemplify with our latest product release, the ZT8441, ZTEC will continue to develop products that drive efficiency, set industry standards, and that our customers can rely on. We are extremely pleased with our expansion into the RF Test Equipment market with our future-proof specifications, our more advanced integration and support, true modular architecture for synthetic instrumentation, and our competitive pricing structure."
ZTEC Instruments adds support for the up and coming IEEE 802.11ac WIFI standard, supporting modulation bandwidths of up to 160 MHz with 80 dB Spurious Free Dynamic Range (SFDR). This is the first product in its class to support the wide channel bandwidth of 802.11ac, a new WIFI standard that is projected to deliver data rates of 1Gb/s.
