MaxwellonTW4207 series Modular Spectrum Analyzer has excellent performance, compact size and cost effective features, which is good choice for system integration. The modular design not only facilitates user integration testing, but also saves costs. You can use the host computer software of the spectrum analyzer to test on the PC, and also integrate it into your system to develop related functions of spectrum analysis. The test results can be obtained from USB and LAN interface directly. Using the standard and complete SCPI command set, the integrated test system can be quickly built and upgraded
