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 measurment conditions.

COUNTER
Counter

Performs frequency measurement with the built-in frequency counter simply by moving the marker to the signal. You can select a measurement resolution from 1Hz up to 1 kHz. The measurement results are displayed with enlarged characters, for easy viewing.

POWER 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 frequendy bandwith (OBW) and adjacent channel leakage power (ACP) which are essential to transmission characteristics testing for radio equipment.

EMC

This function measures electromagnetic interference generated by various electronic equipment. This function incorporates the 9 kHz and 120 kHz RBW and QP detector conforming to the CISPR Pub.16-1 standard. In addition, using the AM/FM demodulation signal fed from the PHONE jack on the rear panel, you can identtify broadcasting radio waves which act as external noise. Prior to measurement of noice emission on the approved site, this function is very useful for preparatory evaluation and solution.

PASS/FAIL

Sets the limited judgment value for the level axis using a window. If the marker falls within the window, the PASS judgment results; otherwise, the FAIL judgment results. Since the limit value is set as an absolute value, you can make measurement with the same judgment value with different REF levels. In addition, by setting the limit window for the frequency axis, the portion where the X and Y axes overlap is judged as the PASS region.

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.

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. In addition, the built-in standard floppy disk drive allows, you to store them on MS-DOS formatted floppy disks.

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 distrortion 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. The PBW calibration function is a new calibration function which performs correction, in power measurement, based on conversion of the R3131 resolution bandwidth filter to an ideal filter, thereby allowing measurement with higher accuracy.
