The 3250 Series has been developed to provide market leading performance at a low cost. The innovative compact design of the 3250 spectrum analyzer employs the latest digital processing and RF technology, providing accomplished accuracy, stability and measurement speed.
To support the constantly evolving wireless communication market, the 3250 incorporates a standard 30 MHz bandwidth digitizer and digital modulation analysis S/W. The instrument has been optimized for various mobile and wireless communication measurements such as GSM/EDGE, UMTS, WiMAX and WiBRO.
With its powerful RF performance and advanced applications the 3250 Series is ideally suited for RF development, design analysis and testing. All models have a Windows® XP operating system, remote control capabilities via LAN, GPIB and RS-232C as well as a 7” touch panel screen, ensuring ease of operation and exceptional connectivity. The internal web server allows remote control from a web browser or tablet PC.
Optional measurement personality libraries for leading wireless communication technologies provide the 3250 Series exceptional measurement and demodulation capability for development and manufacturing engineers to optimize designs, improve throughput or examine signals.
Optional EMI Receiver and preselectors add comprehensive pre-compliance testing capability.
Optional Tracking Generators
Tracking generator options are available for all frequency models. The tracking generator has a specified frequency range of 9 kHz to 3 GHz or 8 GHz and a level range from 0 dBm down to -30 dB. The tracking generator can be used to make high dynamic range measurements on components and devices, particularly filters. A normalize function is available to allow the markers to display relative flatness/frequency response.
