I just picked up a used Rigol DSA815-TG and I am in the process of trying to figure it all out.
Looking at the Options that Rigol offers I am curious about the VSWR Measurement Kit, (DSA800-VSWR) and the VSWR Bridge, VB1020.
I have not been able to find anything that explains what the VSWR Measurement Kit actually does. I assume there is a license, that once purchased, allows the DSA815 to run some additional software and display some additional information.
Can someone shed a little more light on what this option actually allows the 815 to do, and do I really need to consider purchasing it?
Also the VSWR Bridge can be purchased as a bundle with the VSWR Measurement Kit.
I like the idea of a bridge that mates mechanically to the input and outputs of the DSA815, but I know there are other third party Directional Couplers and Return Loss Bridges out there.
My goal is to use the DSA815 to perform Return Loss Measurements on amateur radio antenna systems, (repeaters) and to tune duplexers/cavities on our local area repeaters. For these goals, is the approximatly $600 for the VSWR Measurement Kit something I really need to purchase, or can I make these kinds of measurements without spending the $600 on the software function license?
Thanks,
Keith
