The Gauss Instruments TDEMI device driver is a Spectrum Analyser which is supported by RadiMation®.  

Configuration[edit]

The following tabs are available in the advanced configuration of the GAUSS INSTRUMENTS TDEMI:

The frequency range of the GAUSS INSTRUMENTS TDEMI as provided by the manufacturer is shown and selected as default. It is possible to overrule these frequencies and to manual adjust the allowed frequency range of the GAUSS INSTRUMENTS TDEMI.

ScreenElementDescription.svg Use default start frequency If the checkbox is checked, the default start frequency will be used as the lowest usable frequency in a test for this device.
ScreenElementDescription.svg Custom start frequency If the Use default start frequency checkbox is unchecked, another start frequency (expressed in MHz) can be specified. The customized start frequency will then be used as the lowest usable frequency in a test for this device. The customized frequency can be a limitation or an extension of the default start frequency.
ScreenElementDescription.svg Use default stop frequency If the checkbox is checked, the default stop frequency will be used as the highest usable frequency in a test for this device.
ScreenElementDescription.svg Custom stop frequency If the Use default stop frequency checkbox is unchecked, another stop frequency (expressed in MHz) can be specified. The customized stop frequency will then be used as the highest usable frequency in a test for this device. The customized frequency can be a limitation or an extension of the default stop frequency.


Specifying a different frequency range can be useful if for example:

  • A device (like a coupler, antenna, injection device, cable, etc...) is still useable (but out of specification) outside the standard suggested frequency range.
  • An external mixer is used to measure an extended frequency range.
  • An up- or down-convertor is used to shift the frequency range.
  • A newer model of a device is present that has an extended frequency range, and still uses the same remote control commands.

Be careful changing these setting as RadiMation® is no longer able to verify if the GAUSS INSTRUMENTS TDEMI is used outside frequency range that is specified by the manufacturer. This may result to serious damage of your measurement device.

The Gauss Instruments TDEMI is controlled using an ethernet connection. The RadiMation® device driver is able to control the Gauss Instruments TDEMI using the TCPIP-stream or the VISA-stream. For these connections it is important that the destination port 21683 is used, because that is the network port that the TDEMI is listening on for new connections.

  • For the TCPIP-stream the correct connection string is: tcpip://<IP-ADDRESS>:21683 (where <IP-ADDRESS> is the network IP address and 21683 is the default port of the TDEMI).
  • For the VISA-stream the correct connection string for the Visa-ID is: TCPIP::<IP-ADDRESS>::21683::SOCKET (where <IP-ADDRESS> is the network IP address and 21683 is the default port of the TDEMI).

A Gauss Instruments TDEMI can only be controlled by a single program at the same time. This can raise problems when the TDEMI is controlled at the same time by multiple device drivers (like a Scanning Receiver and a LISN device driver). It is important that all TDEMI device drivers are using exactly the same communication addresses to ensure that only a single communication stream is used to communicate with the TDEMI.
