H5M noise figure analyzers (IKSH) are designed to measure noise figure and transmission coefficient of receiving-amplifying devices. H5M operation principle is based on comparison of measured noise with noise of known intensity, generated by measuring noise generator (NG) characterized by excessive relative noise temperature (ERNT). Measurement is preceded by calibration to determine the characteristics of IKSH receive path, required for precise calculation of gain and noise figure of a measured device.
H5M noise figure analyzers include two device types that differ in operating frequency range:
- H5M-04: 10 MHz to 4 GHz;
- H5M-18: 50 MHz to 20 GHz;
H5M is controlled by external PC with Graphit H5M software installed. The device and PC are communicating via
Ethernet. Multi-channel synchronization system provides
joint operation of H5M series IKSH and other devices.
Control of H5M with SCPI commands provides integration
of the device with automated instrumentation systems.
Depending on combination of hardware options, the noise
figure analyzers are subdivided into versions. You may add
hardware options to the selected version of the device,
which provides extension of device functionality.
