Enhanced Time Domain Analysis (E5071C-TDR) can be controlled remotely.
The figure below shows the connection between a PC, E5071C and Enhanced Time Domain Analysis option. VISA application treats both E5071C and Enhanced Time Domain Analysis option as instruments.
As such, VISA application connects to E5071C via GPIB through GPIB0::17:INSTR address. Standard E5071C commands are sent through GPIB to the E5071C. USB and LAN are alternatives to GPIB.
Whereas, VISA application connects to Enhanced Time Domain Analysis option via SICL LAN through TCPIP0::localhost::inst0::INSTR address. E5071C-TDR commands are sent through SICL LAN to the Enhanced Time Domain Analysis option.
To learn more about other remote control system, refer to Types of remote control system.
SCPI commands and COM commands are used to control E5071C remotely. However, only SCPI commands can be used to control the Enhanced Time Domain Analysis option. Therefore, it is not possible to control it by built-in VBA.
