R3131 Spectrum Analyzer A personal spectrum analyzer utilized in diverse applications R3131
The R3131 is an easy-to-use personal spectrum analyzer which combines high accuracy necessary for digital radio measurement with excellent operability and usability. The R3131 can be used in diverse fields, for a multitude of applications. Front Panel Layout Data Entry Keys Floppy Disk Drive Common Keys The data entry keys arranged together with the FREQ, SPAN, and LEVEL basic functions improves operability. Measurement parameters and results can be recorded on a 3.5-inch floppy disk.

Independent operation keys improve operability AUTO TUNE COUNTER 4 R3131-2E Apr. ´98 AUTO TUNE Searches for the signal with the maximum level within the 3 GHz band and sets the center frequency automatically. Then, reproduces the setting which existed immediately before execution of AUTO TUNE, allowing observation under the same measurement conditions. COUNTER Performs frequency measurement with the built-in frequency counter simply by moving the marker to the signal.
PERSONAL SPECTRUM ANALYZER POWER POWER MEASURE MEASURE The R3131 can measure the power within the specified band of frequency diffuse signals and the total power of multi-carrier signals. It can also be used to measure the occupied frequency bandwidth (OBW) and adjacent channel leakage power (ACP) which are essential to transmission characteristics testing for radio equipment.
GATED SWEEP Bursted signals could not directly be observed with former spectrum analyzers. The R3131 allows spectrum analysis of the burst signal by supplying a trigger signal synchronizing with the burst transmission. GATED SWEEP OFF GATED SWEEP ON SAVE/RECALL The R3131 allows you to store and recall measured waveform data and measurement conditions. The R3131 unit offers up to 10 dedicated files for storage.
Diverse measurement functions The MEAS key incorporates the XdB Down measurement function which is useful for noise measurement, AM modulation measurement, 2-signal 3rd-order distortion measurement, and filter cut-off frequency measurement. In noise measurement, bandwidth conversion can easily be made and the PBW calibration function for improvement of measurement accuracy is effective.
PERSONAL SPECTRUM ANALYZER Improved system throughput The throughput of production and adjustment lines is largely affected by the measurement time of measuring instruments and data transmission time. With newly developed internal processing technology, the R3131 has shortened the time necessary for GPIB control and data transmission by half or more in comparison with former products. In addition, by reducing the settling time of the local oscillator, the waveform update rate in unit time has been doubled.
OPTION Tracking generator option (OPT.74) The tracking generator (OPT.74) is a monoblock option which is integrated in R3131. It can generate constant level signal synchronized with sweep frequency in the frequency range up to 3 GHz and therefore can easily measure the frequency characteristic of object device. Besides, with the normalize function which cancels the frequency characteristic of measuring system, highly accurate measurement is possible.
