Hi tautech! Thanks very much for your kind help! That device will be exactly what I need.
This suggests that at least one of the USB ports of the SDG-1025 can connect to the external interface adapter. I'll see if my 82357B adapter (soon to arrive) will work once it gets here. If not, then that siglent USB-GPIB adapter should definitely get me the right path. Thanks very much again! Greatly appreciated.

The only bugbear with the Siglent GPIB adapter is the USB plug is USB-A which then ties up the front panel USB socket. We've made suggestions that they change it to USB-B so that it can be used in the rear USB socket, leaving the front panel socket free. Would make for a tidier installation too. ;)

Nice suggestion tautech! I thought I read somewhere that one of the USB ports (maybe the rear port) had some different capabilities as compared with the front port. I think I need to find the source of that reading source, just to see what they meant. But, if both the front type A female port and the rear type B female port have identical USB capabilities, then making the siglent adapter have a type B male plug would be very nice.
Otherwise, a female type A to male type B adapter could possibly be used with the current version of the siglent adapter. Or maybe the siglent type A male plug can be snipped off, and a type B male plug could be fitted/soldered to the cable. Thanks again tautech!

Forgive me but I am wondering why (expensive, near obsolete) GPIB is a requirement in this day and age when USBTMC is available and a VISA driver doesn't care if your instrument is connected using GPIB, RS232, USB or LAN?
I am yet to indulge in a GPIB->USB adaptor but I am sure I will need it one day with very old equipment, just so I can plug it into my USB hub much like my Serial->USB leads. But it seems SouthPark's requirements are the opposite way around? - Siglent USB -> GPIB
No criticism, there must be a good reason?

I too wondered why SP needs GPIB and he didn't get one of the new X series models with their additional LAN connectivity, bigger displays and increased and improved functionality, but all this comes at additional cost that some can't justify. Maybe that ? :-//

Thanks for contributing Macbeth! If I have a bunch of GPIB devices, is it possible to use this USB-TMC method to link them all in? For example, use a single GPIB-USB adapter and plug the GPIB connector end into a GPIB function generator, and daisy-chain that GPIB bus to other GPIB instruments, and the USB connector (of the GPIB-USB adapter) connects to a computer/PC. And the computer will be able to see all the devices and control them all, right?
And if we have a bunch of instruments having USB-TMC capability, then we just need a USB hub to connect them all together, right?
If that can be done, then I'll be too happy to go for that method. I didn't know about USB-TMC before.
My SDG-1025 user manual just says "To Set IO, Press Utility ? IO Setup, to set the IO interface. The equipment stands for RAW protocol and TMC protocol, user may setup corresponding protocol by IO Setup."
Your contribution is truly appreciated, because things are now becoming more clear to me about how to best use the SDG-1025 together with other instruments (like GPIB instruments). Thanks Macbeth!
