In the "Spectrum Analyzer" menu, you can perform a deep analysis of the radio emissions in the environment where the unit is placed. The unit scans the radio spectrum on all available frequencies. In order to obtain the information as accurate as possible, the scanning process may take a while.

The following parameters are available in order to operate the Spectrum Analyzer:

ParameterDescription

Start Frequency

  • Set the first frequency for scanning (in MHz)

Stop Frequency

  • Set the last frequency for scanning (in MHz)
Scan step
  • Set the scanning frequency step (in MHz)
  • It is recommended to set 1 MHz “step” value to get more precise scanning results

Channel width

  • Set the bandwidth (in MHz)

Scan Duration

  • Set the time period for the scanning process (in seconds)
  • After the end of this time period, scanning is stopped and the radio interface will be back to its normal mode operation
Table - Spectrum Analyzer

Start/stop Spectrum Analyzer by clicking the «Start Sensor Test»/«Stop Sensor Test» buttons.

By clicking the «Last Snapshot» button, you get the final scanning results. The most common usage of this feature is when you perform a spectrum scan at the remote unit on the other side of the radio link. When running a spectrum scan at such a unit (accessible via the RF interface), connection to this unit will be lost for a scan time. "Last Snapshot" option allows viewing scan results when the connection gets up again.

When you run spectrum scan on a local unit and the link is interrupted, the remote unit will not disappear from the spectrum picture. So you should silence the remote unit in order to have a real picture without it, otherwise you will always see noise signal on the operating frequency generated by the remote unit.

You can get detailed information about the scanned radio signals on a specific frequency. Just point a cursor on the needed frequency and you will see a hint with exact Signal level (dBm), Frequency (MHz), Noise Floor (dBm), RSSI (dBm), High RSSI (dBm), Max RSSI (dBm) values.
