Medical Interference Hunting CapabilitySource: Anritsu Company
With a spectrogram you can notice reoccurring signals that may be missed when using a traditional spectrum analyzer view. The spectrogram shows a sequence of sweeps over time with signal amplitude shown in color.
You can easily create limit lines that enable you to save only signals that exceed the limit line. A limit line can have up to 40 segments, allowing easy tailoring of the limit line to avoid existing known signals.
Save on event
Interference that occurs intermittently can be successfully captured using a limit line in conjunction with Save-on-Event. The saved spectrum analyzer sweeps can be turned into a spectrogram using Master Software Tools (MST), a product that is included with each spectrum analyzer at no additional cost.
By using a USB thumb drive, saved files can be easily transferred into a computer for further analysis and for the creation of spectrograms in MST.
Master Software Tools has a function called "remote access" allowing you to operate your MS2721B over a LAN.
Light weight, battery powered
When walking the halls of a hospital, having a light-weight, battery-powered instrument makes tracking down interfering signals much easier than with AC powered instruments that are pushed around on a cart and must be plugged in whenever measurements are desired.
With the Interference Mapping option available for the MS2712E and MS2713E, interfering signal levels can be shown on the hospital floor plan.
The LAN interface enables external control of the instrument.
Here is another category of measurement that would be useful for installing and maintaining the cables and antennas used for patient telemetry systems.
Line Sweeping – cable and antenna measurements
S331E and S332E would be good choices for this application. The S332E could even be used for interference hunting since it includes a spectrum analyzer.
