The interface identifier for which the radio environment is monitored.
MACCPE MAC address to analyze. If not specified, information is displayed for all CPEs.

Allows to select MAC addresses analysis mode to estimate the number of clients with different MAC addresses and the efficiency of their radio link utilization.

  • "mac" – analyze data packetsonly.

  • "mac2" – analyze data packets and link-level ACK messages (if possible).

  • "mac3" – in addition to mac2 mode, includes impulse noisy signals calculation. Shows number of detected pulses, their average signal level and pulses per second information pulses noise counter:

    • The first value is the number of electromagnetic energy peaks during the scanner operation. The Pulses counter includes frames for which the modulation and source MAC address could not be recognized.
    • The "SNR" value shows an average noise level, the first value is a noise level relative to the receiver sensitivity at a given modulation (dB), the second is an absolute input signal level (dBm).
    • The "PPS" value indicates an average pulses per second number. The value over 50 pps indicates a high noise level.

  • "mynet" – analyze only packets from the given network.


Provides deep analysis of radio emission sources within the given network. In this mode, the device scans the radio spectrum on all frequencies and for all modulation types. Information is displayed on any source of irregular (non-repetitive) radio signals.

To obtain information as complete as possible, the scanning process may take significant time.

-pAllows to show the result as plain text (without the cursor control commands). It can be useful in case of including scan results in a diagnostic map or running scan process via web-interface (Remote Commands).
-tXXSpecifies the time duration, in seconds, for which the test mode is enabled (2 minutes by default). The "0" value cancels the time limit completely.
-lXXSpecifies the number of lines on the screen for displaying test results (24 lines by default).


If specified, the analysis is carried out in the background, the results will be recorded in the system log.

sensor [record=SEC] [F1 [F2] [BW STEP]]

Enables the spectrum analyzer mode, provides deep analysis of radio emission sources. Information is displayed in a alphanumeric format.


Running "Spectrum Analyzer" mode disturbs normal operation of the radio module and makes it impossible to access the unit via radio.

  • "F1" – sets the initial frequency for scanning in MHz. Minimal available frequency for the given equipment model is used by default.
  • "F2" – sets the ending frequency for scanning in MHz. Maximal available frequency for the given equipment model is used by default. The actual shown ending frequency is limited by the size of the program window.
  • "BW" – sets bandwidth in MHz. Allowed values are 1/5/10/20 MHz depending on the concrete equipment type.
  • "STEP" –  sets frequency changing step in MHz. Allowed values are 1/5/10/20 MHz but no more than defined bandwidth value.
  • "record" – starts spectrum analyzer in the background mode with the specified duration time in seconds. 

The spectrum analyzer mode works on all platforms except H02.

  • "replay" shows the last spectrum analyzer scan result.

stat [clear]

Enables statistic mode which is used to estimate link load intensity for each client. The amount of packets sent and received, and the retransmissions number is shown for each MAC address participating in the data exchange. A large retransmissions number caused by a low signal level or a lot of interference leads to useless channel loading and decreasing the overall network bandwidth.

  • "clear"  resets all counters.
