Rigol LXI access

Rigol devices implement the LXI protocol that allows to send SCPI via LAN connection. Connect a device to your LAN, and if DHCP is working, the device gets an IP address.

Simplest access is via telnet. LXI used port 5555.

telnet  192.168.178.20 5555
*IDN?

netcat is another iteresting command to send/receive via LAN connection. The command above can then be written like this:

echo "*IDN?" | nc -w1 192.168.178.20 5555
Rigol Technologies,DG811,DG8A224003223,00.02.05.00.00

From e.f. Spectrum Analyzer DSA815 we get a screendump in BMP format into file image.bmp with the following line:

echo ":PRIV:SNAP? BMP" | nc -w15 dsa 5555 | dd bs=1 skip=11 of=image.bmp

Rigol DG811 (having USB, but no LAN port) can be equipped with a USB-To-LAN adapter for 10-20 euros (I have a UGREEN 20254) which then enables DG811 also to be part of your LAN.
