design

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.
