DragonRF is designed to support the latest wireless communication standards whether it’s an RF Power Amplifier or a RF SOC application. Leveraging the extensive Cohu wireless modulation and demodulation library, DragonRF supports the complete set of tools to test cellular GSM, Edge, GPRS, HSDPA, HSUPA, CDMA, LTE and connectivity devices including BT, BT EDR, BT4.0, GPS, 802.11 a/b/g/n/ac/p and other emerging standards.

DragonRF provides up to 200 MHz IF bandwidth, enabling whole spectrum capture by receiver to support ever-increasing bandwidth in the newer wireless communication standards. Combined with leading Signal-to-Noise Ratio performance and optimized algorithm, DragonRF achieves the fastest and most accurate EVM measurement to test the comprehensive performance of today’s complex RF devices with shortest test time.

DragonRF is designed with universal vector port architecture that delivers the required level of performance with flexible configuration to match the rapidly evolving device testing needs. Each DragonRF can be configured with 16, or 32 universal vector ports.

DragonRF can also be configured with 1, 2, 3, or 4 RF synthesizers to provide octal site modulated RF stimulus to the devices, and with 2, 4, or 8 RF measure paths for true parallel octal site RF measurements.

DragonRF uses the latest technology in RF synthesizer and RF control circuitry in its design. The Rohde and Schwartz SGS100 RF source is used as the synthesizer in DragonRF, utilizes the latest synthesizer architecture and software.

Combined with all CMOS RF paths in the new DragonRF module, DragonRF provides fast level and frequency settling time to 0.05 dB less than 1ms, greatly enhancing the test throughput, and lowering the cost of test.

DragonRF’s fully automated calibration process allows greater tester up-time and reduces operator-induced errors and variations. The DragonRF Auto Calibration kit offers a single self-contained calibration unit that provides:

  • Calibration of RF source, scalar measure, noise, and S-parameter measure
  • Internal R&S power sensors
  • NIST traceable integrated RF power meter and noise source
  • Factory calibrated RF Autocal fixture

The Unison software environment provides users with fast single site program development, instantaneous multi-site testing capability, and test IP that can be transferred from device to device. Unison features cutting-edge productivity tools that accelerate development and debug time, shortening the time to high volume production for current and next generation products.

Every RF receiver is equipped with real time Dynamic Range Enhancer (DRE) with embedded DSP capability. With DRE enabled, DragonRF provides more than 30 dB dynamic range, which is critical for RF measurements, especially ACPR. This enables faster test time, rapid correlation between ATE and bench-top instrument, and it improves yield with extra margins above the noise floor.
