Anritsu MS2601B

The MS2601B is a wide-band spectrum analyzer which covers the video to VHF/UHF bands. The synthesized local oscillator and automatic calibration, which uses a highly accurate signal source, enables accurate frequency and level measurement.

The MS2601B has new and original functions such as the zone marker and scroll function that shorten measurement time. Furthermore, plug-in memory cards (PMCs) for storing measurement conditions and waveform data offer excellent operability.

The MS2601B automatically calibrates itself using the calibration signal from the built-in signal source each time the CAL key is pressed. The calibration data is processed at high speed by a 16-bit microprocessor and the compensation value is added to the displayed measured value.

The reliability of measurements has been greatly improved and the measurement error has been reduced to about one-third of conventional models, resulting in a general level measurement accuracy of 1 dB.

Digital technology of MS2601B, including a synthesized local signal, has been used to greatly improve the level measurement accuracy. Also, the signal peak-level frequency can be measured with 1 Hz resolution even at a 2.2 GHz full sweep.

In addition to having a QP detector, three resolution bandwidths, and time constants based on CISPR standards, the antenna calibration coefficients are automatically calculated to facilitate the best EMI measurement.

The MS2601B uses IC memory cards called PMCs to store measurement conditions and waveform data. For example, once the test procedures are stored in the PMCs, measurements can be made under the same conditions at any time.

The PTA function is a high-level language for measurement and a computer integrated in a spectrum analyzer. Programs for measurements, operation and display can be input to the MS2601B via the keyboard or a personal computer.

The spectrum analyzer can be configured quickly into automatic test equipment. PTA supports complicated measurements as well as preparation of final test results.

The MS2601B can be used as a frequency counter, power meter, and real-time computer for measurement operations, or as ATE combining these functions, as well as a spectrum analyzer. Also, various support software is available to enable connection to factory automation LANs (local area networks).

Reproducible high-accuracy level measurements are ensured through internal signal calibration, initiated simply by pressing the CAL key on the MS2601B. In addition, there is little cumulative LOG linearity error so that measurements of transmission characteristics are carried out with the same high accuracy achieved by network analyzers.
