Interference detection and location in professional radio networks Its compact design and wide range of special f unctions make the R&S®PR100 an ideal choice for tracking all types of radio interference. Reliable detection of radio interference caused, for e xample, by defective electronic equipment To master these tasks, the R&S®PR100 includes s ecial p functions such as selectable measurement time and c ontinuous or periodic level output. Since these functions are also effective in the panorama scan mode, even nonperiodic interferers, which are otherwise difficult to recognize due to their...

Monitoring of user-specific radio services The frequency scan mode is mainly intended for monitoring radio services that use fixed channel spacing. Monitoring of a large number of radio services with ifferent scan modes d In the frequency scan mode, a user-defined frequency range is scanned using fixed channel spacing. The eceiver r steps through the frequency range of interest and checks every channel to see if any signals are resent. If a signal p is detected that exceeds the predefined level threshold, the receiver dwells at the corresponding frequency for the set hold time, allowing for the...

Homing of emergency signals Transmitters can be tracked not only visually by displaying the received signal level or the spectrum, but also acoustically with the tone function. Location of source of emergency call with the R&S®HE400 handheld directional antenna For example, if an emergency transmitter has been identified at a specific frequency, the user can activate the tone function in order to locate the transmitter. This function causes the receiver to output a whistling tone whose pitch varies with the level of the signal received. The signal level, in turn, varies as the user changes position...

Location of improvised explosive devices (IED) By approaching the signal source, the R&S®PR100 can locate even extremely weak signals in difficult terrain. Detection of IEDs even when they are in standby mode For example, the oscillator reradiation of an IED (once the frequency is known) is visible on the display of the R&S®PR100 even if the IED device is operating in the receive-only mode. The receiver of a remote detonation device leaves traces in the frequency spectrum even in standby mode. Oscillator reradiation and other spurious effects caused by remote control electronics are unintended...

Mobile racking t of miniature transmitters The R&S®PR100 portable receiver offers high m obility plus a convenient carrying strap, making it perfectly suited for all kinds of mobile applications. Detection of bugs, e.g. in conference rooms The R&S®PR100 can easily detect all types of miniature transmitters (bugs) as it approaches them. Its wide frequency range from 9 kHz to 7.5 GHz covers the frequency bands of the majority of miniature transmitters used today. For frequencies above 7.5 GHz, the R&S®HF907DC f requency-converting, portable directional antenna can be used to expand the receive...

Triangulation to ocate signal l sources in manual DF mode Manual direction finding of a signal source with the R&S®HE400 handheld directional antenna The desired direction information relative to north is obtained by manually lining up the R&S®HE400 in the receive direction where the signal is strongest. This information is shown on a compass rose on the R&S®PR100. Combining this information with the receiver’s GPS position gives the user clear position and direction information that can be used to approximate the location of the signal source. Several DF results can be combined to more exactly...
