Spectrum analyzers leverage burst-detect mode
Test & Measurement World Staff - August 3, 2012
Anritsu has introduced burst detection as a standard feature of its MS272xC Spectrum Master series of handheld spectrum analyzers, enabling field engineers and technicians to find narrow signals that may cause interference and adversely affect the performance of wireless networks. In burst-detect mode, the MS272xC can capture up to 20,000 measurements/s—thousands of times faster than a normal FFT.
According to the manufacturer, pulse trains as narrow as 200 µs can be seen every time. This makes it easier to locate burst signals, such as those generated by improperly installed cell-phone boosters.
The fast measurement time and subsequent ability to detect burst signals is achieved, in part, by the ability of the MS272xC to conduct a Max Hold function in hardware. For every display update, the Max Hold is reset, making it possible to see changes in the signal. All trace modes, including Max Hold, Min Hold, and Average, are available with the burst-detect method.
Comprising five models, the Spectrum Master MS272xC series covers a frequency range of 9 kHz to 43 GHz with resolution bandwidths from 1 Hz to 10 MHz and a dynamic range of greater than 100 dB. The portable instruments also offer a 30-MHz zero-span IF output and advanced triggering, including hysteresis, hold-off, and delay.
Starting prices for the MS272xC series of spectrum analyzers range from $15,950 for the 9-GHz model to $42,950 for the 43-GHz model.
