 R3271 can be used for the analysis of radar pulse RF signals, or analysis of satellite broadcasting, satellite communication or mobile communication used in the microwave and sub-millimeter-wave spectrum. R3271 can be measured in a scanning motion from 100Hz ~ 26.5GHz ultra-wide bandwidth. It can also be continuous, repetitive scanning. A newly developed high-purity synthesizer makes less than the 2.5GHz frequency band can be achieved? 10dBc/Hz high signal purity (10kHz offset frequency). So R3271 for the use of narrower bandwidth and higher digital mobile radio communication is very appropriate. In the past, such high-performance equipment for advanced research and development only, but now, a wide range of industrial and commercial areas in need of such performance, so Advantest using the latest technology to produce such a high-performance microwave spectrum analyzer. 

 Introduction to the main performance 

 Accurate calibration software 
 The CPU is not only an internal calibration intermediate frequency (IF), but also the correct frequency, including the attenuator in order to improve the accuracy of amplitude measurement. Noise measurement, power bandwidth can also be corrected. 

 Large screen display using portable systems 
 R3271 uses an eight-inch screen to monitor the measurement results, so you can monitor performance to ensure the accuracy and easy operation. 

 High spectral purity 
 Below the 2.6GHz frequency band, using a newly developed high-purity synthesis of high signal purity available -110dBc/Hz (10kHz offset frequency). This can be in a very wide dynamic range measurements close to the launch of distortion. And 10kHz offset at 23GHz frequency, -110dBc/Hzz signal purity available. 

 Over a wide frequency and dynamic range measurements 
 R3271 in the 100Hz to 26.5GHz frequency range of repetitive, continuous scanning. Using a low-noise IF amplifier to reduce the noise level. Preselector also expanded the dynamic range of amplitude measurement. 

 The frequency resolution of 1Hz counter 
 Degree by using a stable reference oscillator 2 × 10-8 (or optional 5 × 10-9 / day), 1Hz resolution frequency counter can generate stable and accurate frequency measurement. As measured by strong signals, like the hidden signal frequency, frequency counter to accurately measure the weak signal.
