Block diagram for the RSP2?

Has anyone ever seen a block diagram of the RSP2 ? It would be very interesting for everyone.

We've already raised this matter. The RSP-1 blocks and schematics were published, so it would be nice to have them for the RSP-2 so we could see the changes to the antenna switching and the RF filtering.

The layout on the board is well structured. It is quite easy to follow the signal paths and identify the functional blocks.

The HI-Z input has its own signal path:
input port ->
low pass filter (symmetrical) ->
MSI001 input.

Port A/B:
Input port A/B ->
switch, port A/B ->
LNA, fixed gain ->
attenuator, 8 steps ->
BC band reject filter, switched ->
filter bank: 0-12MHz, 12-30MHz, 30-60MHz, 60-120MHz, 120-250MHz, 250-300MHz, 300-380MHz, 380-420MHz, 400-1000MHz, 1GHz HP
MSI001 inputs (6)
