RSP2PRO vs RSP1a

I am not sure if this has been asked previously but can someone explain the fundamental difference between the RSP2PRO and the RSP1A.

Thank you

The most obvious difference is the three selectable antenna inputs on the RSP2. Two SMA types which are best for VHF and the high-z terminal block which is optimised for 0 - 30 MHz.
The RSP1a has only one input but the input filters and signal routing has been changed to make it suitable for all frequencies. There has also been a small adjustment to enable the ADC to work in 14-bit mode at spans under 6 MHz, but I doubt the difference will be dramatic.

Thank you Andy.

I had the RSP2pro which I have passed on. I note that the RSP1a does appear to perform as near as the RSP2 from video clips published on Utube.

I may decide on the RSP1a.

Thanks again.
