      產品詳細介紹Product Introduction

      All-standard 0-3GHz modulator for PCIe
      DekTec's cutting-edge, all-digital modulator with advanced synchronization features supports a wide range of modulation standards. It's the ultimate tool for generating high-quality RF signals, from test modulation to SFN operation and GPS simulators.

      Features
      • Versatile: Supports a wide range of cable, terrestrial, and satellite modulation standards. Also generates arbitrary RF waveforms.
      • All-digital: High-quality, low-noise output signal through SDR and digital upconversion.
      • Synchronization: Enables SFN and multi-Tx antenna simulations through high-precision syncing to an external clock reference.
      • Programmable: All parameters are software-adjustable for automation purposes.
      • 80dB: Impressive output level range!

      Applications
      • R&D: Ideal for developing and testing digital TV equipment, as well as experimenting with new RF modulation schemes.
      • Broadcasting: The high signal quality makes the DTA-2116 an excellent choice for actual broadcasting applications.
      • Automatic Testing: Automatically cycle through a range of frequencies, levels and modulation parameters, making it useful for factory testing and automated quality control.
      • Simulation: Simulate GPS, MIMO, or any other multi-transmit antenna configuration.

      Block Diagram
      The DTA-2116 is an all-digital modulator that generates a high-quality RF signal. Unlike traditional analog modulators, it performs all signal processing digitally, providing increased flexibility and precision. See the functional block diagram below.

      The DTA-2116 receives I/Q packets generated by a software modulation process over the PCIe bus. The I/Q packets are buffered in a DDR memory-based transmit FIFO before further processing. The DTA-2116 then performs channel filtering, resampling, gating, and digital upconversion to generate a digitally upconverted modulated signal, which is then converted into an analog RF signal by a high-performance RF-DAC. The analog RF signal is low-pass filtered and amplified or attenuated with a programmable gain.

      The DTA-2116's master clock generator synchronizes the device's oscillator to either an internal 10MHz oscillator or an external 10MHz timing reference for more accurate or synchronized timing. The Sync block enables synchronous starting with the 1pps input signal, facilitating precise synchronization between multiple modulators.
