K4M spectrum analyzers are designed to measure level and frequency of harmonic components of periodic signal spectrum, and spectral power density of stationary random processes. Use of linear path with wide dynamic range designed in superheterodyne circuit with synthesized heterodynes, in combination with digital processing unit for intermediate-frequency signal provides solution for a wide variety of tasks arising in analyze, development, manufacturing and operation of radio electronic devices.

 SK4M products include two types of analyzers with different operating frequency ranges:

  • SK4М-18: 100 Hz to 20 GHz;
  • SK4М-50: 100 Hz to 50 GHz.

SK4M is controlled by external PC with Graphit SK4M software installed. The device and PC are communicating via Ethernet. Multi-channel synchronization system provides joint operation of the analyzer and other devices. Control of SK4M with SCPI commands provides integration of the device with automated instrumentation systems. Depending on combination of hardware options, spectrum analyzers are subdivided into versions. You may add options to  the selected version of the device, which provides extension of device functionality.
