The 3250 Series has been developed to provide market leading performance at a low cost. The innovative compact design 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 basic digital modulation analysis software. The instrument has been optimized for various mobile and wireless communication measurements such as GSM/EDGE, UMTS, WiMAX, and WiBRO.

• 14 bit ADC with 85.6 MHz sampling frequency
• Dynamic range over 80 dB
• 32 M samples data with 128 M memory
• Standard FFT, spectrogram, digital modulation analysis
• Save I/Q data file
• Digital modulation analysis like PSK (8, 16, 64), QAM (4, 8, 16, 32, 64, 128, 256), BPSK, QPSK

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.

Optional measurement personality libraries for leading wireless communication technologies provide the 3250 Series excellent measurement and demodulation capability for development and manufacturing engineers to optimize designs, improve throughput, or examine signals.
