R&S^®PR100 Portable Receiver

Intuitive, simple operation

The operating concept of the R&S^®PR100 meets the requirements placed on a modern radiomonitoring receiver, i.e. all important functions such as demodulation modes and bandwidths can be set directly using clearly labeled keys. Users are quickly able to use the receiver.

The receiver is controlled conveniently via keys and the rotary knob. Clearly structured menus provide quick access to instrument parameters and functions.

Results, as well as the spectrum and waterfall diagrams, can be read at a glance on the bright, well-organized 6.5" VGA color display. The backlighting of the display can be dimmed for use in dark surroundings. For use in sunlight, a special black-and-white display mode is available that optimizes contrast.

The IF panorama display facilitates the detailed analysis of a frequency range of interest. The current receive frequency is positioned at the center of the spectrum display. IF bandwidths between 1 kHz and 10 MHz can be selected to suit the task at hand. The Average, MinHold and MaxHold functions further expand analysis capabilities.

The user can change how the results are displayed to meet the current requirements. Measured data is available in various formats.

Digital data is output via the LAN interface:

• Complex baseband data (I/Q data) up to 500 kHz bandwidth
• Digital audio data up to 12.5 kHz bandwidth
• Spectra of panorama scan (with maximum update rate)
• Spectra of IF panorama display (with maximum update rate)
• Measured signal levels
• Measured frequency offset values
• Measured field strength values (antenna factors of antenna used must be stored in the receiver)

Analog data is output via the corresponding analog interface:

• Analog audio data via 3.5 mm jack
• 21.4 MHz uncontrolled IF via BNC socket (for receive frequencies from 20 MHz to 7.5 GHz)

The user settings and level indication modes become effective at different points in signal processing. This is explained in greater detail in the Operating principle section, which uses block diagrams to describe the R&S^®PR100’s operation.
