Portable spectrum analyzer up to 18 GHz Rohde & Schwarz FSH18

MAIN CHARACTERISTICS

The Rohde & Schwarz FSH18 is the ideal tool for fast, high-precision signal exploration at minimal cost. It has a large number of measurement functions and thus can be used in everything from installing and maintaining a cellular base station to finding faults in RF cables.

The available models of the R&S FSH have an upper frequency of 3 GHz (the instrument R&S FSH3), 6 GHz (instrument R&S FSH6) or 18 GHz (R&S FSH18) and with or without an internal tracking oscillator. Most models have an adjustable preamp, which makes it possible to measure very weak signals. Two types of power sensors are available as accessories. One is for high-precision matched-line power measurements up to 8 GHz or up to 18 GHz, and the other is for directional power measurements up to 4 GHz. The tables below show the configuration required for each application and a summary of the supplied models.

 

TDMA Power Measurement

With the TDMA POWER function, the R&S FSH18 performs time domain power measurements within a time slot in time division multiple access (TDMA). All settings required for GSM and EDGE standards are defined in the R&S FSH 18 to make measurements easier for the user.

 

Field strength measurements

The R&S FSH18 takes into account the gains of the connected antennas when making electric field strength measurements. The field strength is displayed directly in dBµV/m. In addition, it is possible to correct frequency-dependent loss or gain, for example, for a cable or an amplifier. For fast and easy analysis results, the R&S FSH18 offers two user-defined limit lines along with automatic limit monitoring.

 

Channel power measurements

The R&S FSH18 determines the power of the selected transmission channel using the corresponding function. Channel power measurements for 3GPP, WCDMA, cdmaOne and cdma2000 1x digital radio standards are performed with just one keystroke, if the instrument is set to the correct settings.

 

Receiver mode

The R&S FSH-K3 option allows the R&S FSH18 to be used as a monitoring or EMC prequalification receiver. Measurements are taken at a specific frequency with a user-selectable measurement time. In scan mode, the R&S FSH18 measures the level successively at different frequencies set in the channel table. The channel table is created using the R&S FSH View software and then downloaded to the R&S FSH18. For some mobile communication standards and TV standards, there are already ready-made tables. In addition, the instrument has 200 Hz, 9 kHz, 120 kHz, and 1 MHz band pass filters for CISPR radiated RFI measurements. Peak, average, RMS and quasi-peak detectors are also available to the user.

 

Directional power meter

The R&S FSH-Z44 directional power sensor turns the R&S FSH18 into a full-featured power meter in the frequency range from 200 kHz to 4 GHz. With this add-on, it is possible to simultaneously measure the output power and the matching of a transmit antenna system under field conditions. A directional power sensor measures values up to 120 watts and typically does not require additional attenuators. It is compatible with common GSM/EDGE, 3GPP WCDMA, cdmaOne, cdma2000 1x, DVB-T and DAB standards.

 

R&S FSH View control software for the R&S FSH18 spectrum analyzer

A software package for documenting your measurements is supplied with every R&S FSH18:
- Runs under Windows 98/ME/NT/2000/XP operating systems;
- Fast and convenient data transfer from R&S FSH18 to PC and vice versa;
- Converting data to ASCII or MS Excel format;
- Printing out all existing information using Windows (printing an image from the R&S FSH18 screen for documentation);
- Graphic data is stored in standard formats (.bmp, .pcx, .png, .wmf);
- Permanent and continuous transfer of sweeps to a personal computer; the possibility of further analysis (markers, scaling, etc.);
- Saving sweeps and other information about measurements; comparison of old and new measurements (the amount of memory is limited only by the size of the hard drive of the control computer);
- Automatic saving of measurement results in selected intervals;
- Obtaining data about the cable using the built-in editor; data upload to R&S FSH18 for distance-to-fault measurements (R&S FSH-B1);
- Editor for generating limit lines, conversion factors and correction factors for external attenuators and amplifiers;
- Macro Word function, for quick and easy documentation of measurement results;
- Connection of the instrument to a PC via an interference-free RS-232-C interface with optical isolation.

 

Convenient, reliable and mobile

The R&S FSH18 spectrum analyzer is a robust instrument that can be used in the field.

The R&S FSH18 can also be used in the laboratory. The device has an adjustable, folding stand, which allows you to place it at an angle that is optimal for viewing.

For easy transport, the R&S FSH18, together with accessories, can be stored in a compact and robust aluminum case.
