1. I have done it few times, never had a problem. It’s a signal generator so you can say it’s for audio testing etc. Take it in your carry on, don't check it in your luggage. In the US, it will need to come out of the bag like you have to with laptops since it is large electronics.
2. I have just the other day Auckland to Manila. 1 GX in cabin baggage (No problem at security checks) Plus also another GX and XM in my checked luggage plus ancillary equipment, again no problem.
3. I pulled it out along with my laptop. I had put it in a travel case they didn’t even ask me to open the case. I assumed they thought it was all electronics.
4. I’m on the road every other week. I typically put my equipment in my carry-on and hands carry it. Every now and again I got asked to take it out. I’ve never had any problems with it being x-rayed.
