Announce a few days ago Tyke company,in in carry by real-time spectrum analyzers RSA3000B series in increase by DPX? Digital fluorogenic technology. The engineer can use RSA3300B and RSA3408B series real-time spectrum analyzer, look over the spectral RF signal in real time in unique way, offer the unprecedented RF signal for the fact that various figures RF are employed and look over the function, including RFID, radio management and management of frequency spectrum. DPX can change a large number of real time data, produces the real-time RF spectral picture, announce RF signals and unusual signals that could not be seen in the past.

Figure RF applied fast enlargement, is promoting a lot of applied measurement demands to improve constantly, such as the mobile communication and management of frequency spectrum, these demands have already gone beyond frequency sweep analysis and analytic ability range of vector signal. Signal, RF of figure, bear the weight of complicated modulation, from one piece transient to vary to next and transiently, frequency hopping, reach the overshoot in a short period of time, then disappear. These time varying transient signal transmission technology helps RF apparatus to avoid the interference, improve peaking generation to the maximum extent, can usually avoid verification.

Because deal with several centuples higher of the spectrum analyzers of other manufacturers of velocity ratio in frequency spectrum, RSA3300B series and RSA3408B 100% intercept very short transient signal while being all right, transient signal that RSA3408B intercept may up to 31 microseconds while being most short, it can be up to 41 microseconds that the transient signal that series RSA3300B intercept is the shortest. In addition, touch off ability in unique time domain and frequency domain transient signal, series RSA3300B and RSA3408B can be diagnosed in an incomparable way and debugged the figure RF to design.

RSA3300B series divided into two kinds of frequency domains of DC-3 GHz and DC- 8GHz. RSA3300B has been offered dynamic range of spurious signals (SFDR) does not in acquisition bandwidth and 70 dB of 15 MHz ,Especially suitable for using for designing and debugging 3G mobile communiation system, the near-field system (such as RFID and bluetooth) And the communication system of narrow bandwidth and medium-sized bandwidth.

Besides real-time RF, the digital fluorogenic processor has offered the grade afterglow of brightness to reveal, can keep the unusual signal, until the engineer sees them, reveal emergence history of the dynamic signal, offer the feedback related to the fact that the signal is time varying immediately. The engineer can look over the transient incident sum signal that can not be seen on the screen in ordinary way rapidly, because other signals have concealed these signals, or look over to these signals that could be derived out after time consuming off-line analysis only. DPX digital fluorogenic technology catches unusual signal and transient incident difficult to examine rapidly, have strengthened operating efficiency, has improved the precision and insight, has accelerated designing and debugging the speed.

RSA3408B real-time spectrum analyzer of RSA3000B real-time spectrum analyzer and 36 MHz bandwidth of 15 MHz bandwidth can offer the frequency domain to touch off hitting the end of the function Spectrum analyzer. Its frequency of utilization template is touched off (FMT) The function is carried out, undesired signal and transient signal of finding other instruments.
