  • Network Analyzer

    DPNA-6G AXIe - Holding Informtest

    The AXI DPNA-6G module is the world's first network analyzer in the form factor of the AXIe-1 module, as well as the first Russian device that meets the AXIe-1 standard. In the mode of the network parameters meter, the AXI DPNA-6G module measures the vector values ​​of the network parameters on two ports: transmission coefficients (S12, S21) and reflection (S11, S22). At the same time, all necessary types of calibrations are supported: one- and two-port short-circuit, XX, matched load, transmission normalization. The software supports the import of third party calibration standard parameters. In the measuring receiver mode, the module provides:*generation of a harmonic signal (frequency synthesizer);*spectrum analyzer and power level in a given band;*measuring the frequency of a known signal;*measurement of analog modulation parameters;*phase noise measurement.
