R&S^®PR100 Portable Receiver for Mobile Radiomonitoring

The operating concept of the R&S^®PR100 meets the requirements made on a modern radiomonitoring receiver, i.e. all the important functions such as demodulation modes, bandwidths, etc, can be set directly by means of clearly labeled keys. Menus structured by priority provide quick access to further functions and settings. Measurement results as well as the spectrum and waterfall diagrams are output on the straightforward 6" VGA color display, which can be read well even under difficult lighting conditions. The result display can be changed to suit the particular requirements.

Scanning modes

RF spectrum (panorama scan)

In this mode, the desired frequency range is scanned in 10 MHz steps, and on FFT of 10 MHz width is calculated for each step. Thus, the spectrum of the selected frequency range is shown on the display in realtime.

Frequency scan

This mode makes it possible to define a frequency range to which a complete data record can be assigned. The data record contains the receiver settings as well as scan parameters such as start/stop frequency and step width.

Memory scan

The R&S^®PR100 contains 1000 definable memory locations. The complete receive data record including frequency, demodulation mode, bandwidth, squelch level, etc, can be assigned to each memory location. The memory contents can be sorted according to frequency, name, and memory number.

IF panorama

The IF panorama functionality permits closer examination of the signal spectrum and signal environment. The current receive frequency is positioned at the center of the spectrum display. The display range can be set between 10 kHz and 10 MHz and can thus optimally be adapted to the task at hand. MINHOLD and MAXHOLD functions further expand the applications.

Data output

A variety of data is output via the LAN interface:

• Complex baseband data (I/Q data) up to 500 kHz bandwidth
• Digital video data (demodulated signal) up to 500 kHz bandwidth
• Digital audio up to 12.5 kHz bandwidth
• Spectra of panorama scan
• Spectra of IF panorama
• Offset reading
• Field strength reading (including internally programmed antenna factors of the antenna used)

Remote control

All receiver functions can be remote-controlled via the LAN interface. Even high data rates as occur, for example, in the panorama scan or during transmission of digital baseband data are easily transmitted.

The protocol of the LAN interface is compliant with the Standard Commands for Programmable Instruments (SCPI) syntax.

Data memory

The receiver provides the following facilities for internal data recording:

• 64 Mbyte RAM for recording I/Q data up to 500 kHz bandwidth, or audio data with 12.5 kHz bandwidth
• 4 Gbyte SD card for storing recorded I/Q data, audio data, spectra, and readings (this memory space can be expanded up to 8 Gbyte)

The SD card is read out via the USB interface.

Digital data is recorded in WAV format, readings are recorded in CSV format.

Snapshots of the display can be stored in PNG format on the SD card.

The digital data can also be output in realtime via the LAN interface and recorded externally (PC hard disk).

Offline Analysis

For offline analysis of recorded I/Q-data the R&S^® GX430 software running on an external PC can be used.
