Use TekHSI to connect to DSA72004B

[djsg]

Hi guys,

I have two questions:

1. I have a DSA72004B scope. I wonder if TekHSI supports this model.
2. I connect the scope with my computer through a LAN cable. I managed to ping from my computer to the scope. However, the following line failed.
   with TekHSIConnect(f"{addr}:5000", ["ch1"]) as connect:
   It seems the TCP server in the scope is not running. I wonder if I need to start the TCP server and how to.
