Not recommended, but very inexpensive: Again not recommended, but still inexpensive: Is 500MHz enough for you(?): This may be a good option: This is probably a Best choice: Note that it needs a reference '50 Ohm Termination', and one to check its Return Loss* capability (* you will need this with any RLB you buy, or make). You may want to to do a little research about RLB's to understand and appreciate this. The amount of error, either to the worst, or 'incorrectly' to the better, can be very significant even with a Return Loss Spec. What should a RLB have for a minimum Return Loss (with the UUT port terminated with an excellent 50 ohm termination)? Ideally 30dB minimum for general hobbyist measurements, 35dB is preferred, and 45dB minimum for laboratory type measurements. The VB10220 is a nice clean package, but it doesn't work very well for its intended purpose.

Tell them that the performance is way too low for your use of a RLB, and you will get your full refund.
I would recommend returning your VB1020 for full refund, and by the way you have the VSWR Key, so that will remain on your DSA. All of the units I referenced I think are probably at least as good as the VB1020 (yes, I believe even the cheapest). And then you may want something even better(?). You may be happier using a Return Loss Loss Bridge (that can be adjusted and tweaked at least a little A/R), and there are several available at reasonable cost ($70 to $150 is reasonable). You can also use a Mini-Circuits Directional Coupler (although what you get will be what you will have). I have included some links for Return Loss Bridges that are available. So if you measure your new unit I expect that it could possibly be worse than my test results were. I included a plot of one I tested for a friend in 2013, but please note that they have since reduced the Return Loss Specification to 20dB typical and 15dB minimum. And as a result they have lowered the specifications a couple of time since it was initially released for production. Although I want to to caution you that Rigol has been having problems with their 'expensive' VB1020 VSWR Bridge for the last couple of years. Firetank: Congratulations on you new DSA815-TG.
