Rohde & Schwarz FS300 Spectrum Analyzer

With the new Spectrum Analyzer R&S FS300 from the R&S Smart Instruments™ series, Rohde & Schwarz offers for the first time a professional stationary measurement instrument in the lower price segment. The R&S FS300 features a wide frequency range from 9 kHz to 3 GHz as well as the RF characteristics of a top-end spectrum analyzer. The instrument is of extremely compact design, with a width that occupies only one half of a 19-inch rack and measuring three units in height. Owing to its versatile measurement functions, ease of operation and USB remote-control interface, the R&S FS300 is suitable for a wide range of applications on the lab bench, in a rack or in the field, thus providing an outstanding price/performance ratio.

Features	Benefits
High-quality measurement characteristics: SSB Phase noise -90 dBc (1 Hz) Intermodulation-free dynamic range > 70 dB (TOI > 5 dBm) Displayed average noise level typ. -120 dBm (300 Hz) Level uncertainty < 1.5 dB	Since the displayed average noise level is typically -120 dBm (300 Hz), even weak signals can be reliably detected. This is important for the measurement of spurious and harmonics. Within the intermodulation-free dynamic range of the R&S FS300 no inherent distortions occur, which could interfere with the measurement. This is especially useful when a high dynamic range is required, i.e. high and low levels are to be measured simultaneously. The points in the measurement trace are displayed with a level uncertainty of <1.5 dB. This value is unrivalled in this price class and an essential prerequisite for high measurement accuracy.
Resolution Bandwidth from 200 Hz to 1 MHz	With 16 different digitally implemented resolution bandwidths starting at 200 Hz, the R&S FS300 can be optimally adapted to different measurement tasks. Large bandwidths for overall measurements ensure short sweep times while small bandwidths provide high frequency resolution and low noise level. The R&S FS300 fulfills every requirement in between.
Frequency counter with 1 Hz resolution	With the aid of the built-in frequency counter, the signal frequency can be measured with 1 Hz resolution in the entire frequency range. An additional frequency counter is therefore not required which saves space on the lab bench.
Maximum input level +33 dBm	The maximum input level of the R&S FS300 permits signals to be measured far beyond the common limits. Mobile phones with a maximum output power of 2W can be directly connected to the spectrum analyzer without external attenuators being required.
Ergonomic user interface	Operation is menu-guided so that even untrained users will quickly obtain correct measurement results. Clear structures simplify navigation within the menus. Users familiar with spectrum analyzers from Rohde & Schwarz will quickly find the menu items they know from other Rohde & Schwarz instruments. The bright TFT colour display with 320*240 pixel resolution allows traces to be read even at odd angles or when the incidence of light is unfavourable.
Remote control via USB	Another new feature of the R&S FS300 is the USB remote-control interface. The user can select external PC control even during instrument operation by means of "hot plug and play" simply by establishing a USB connection. This is the first time that lab test equipment can be remote-controlled via USB without any restrictions. With the aid of the USB cable, the R&S FS300 can be operated even at positions which are difficult to access, e.g. in a shielded chamber. A Windows(2000/XP)-compatible driver for different development environments is provided togehter with the R&S FS300. A PC software package is also available for remote control of the R&S FS300 and for result display and recording.
Compact housing with flexible handle	The R&S FS300 is notable for its compact and robust design. Whether on the operator desk or in the rack, it takes up a minimum of space. Two series instruments can even be accommodated next to each other in a 19-inch rack. The new, adjustable handle fulfills several functions. It serves for carrying the R&S FS300. It can be moved and locked in almost any desired position. With the aid of the handle, the instrument can be set up in a tilted position so that an optimum viewing angle can be obtained for the display. If the handle is in the way, it can easily be put away so that several R&S FS300 can be stacked, for instance.
High picture refresh rate	The high refresh rate of up to 10 pictures per second ensures smooth display of measurement results. Changes of parameters during module adjustment are thus rapidly displayed which saves time in development and production.
Various measurement functions	The R&S FS300 offers a number of measurement and marker functions to support signal analysis. Two normal or one normal and one delta marker are provided for determining the signal level. The normal marker may be positioned as a reference marker on the fundamental, for instance, while the delta marker is positioned on a harmonic. The difference between the two levels represents the harmonic suppression. The normal or delta markers can also be used as noise markers for measuring the noise power density. The n dB bandwidth of a signal, e.g. the 3 dB or 6 dB bandwidth, can also be easily measured with the R&S FS300.
Internal memory for settings and traces	Up to five traces and ten settings can be stored in the internal memory of the R&S FS300. Frequently used settings can thus be easily called up and the same parameter need not be set over and over again. This also prevents setting errors on the R&S FS300. The traces stored in the instrument can be called up later and output to a printer, for instance.
