GAUSS INSTRUMENTS TDEMI
TCPIP Connection[edit]
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.
Auto step frequency[edit]
When 'Auto step frequency' selected in RadiMation®, the device driver for the TDEMI will select half of the selected RBW bandwidth, and will configure that in the TDEMI. Thus a 1 MHz RBW will result in an auto step frequency of 500 kHz.
