Well I have noticed a modification on the garden that makes me anxious.

In the QUAD’s features the line:

Two 72Mhz analog channels and two digital channels

has been replaced by:

Two 36Mhz analog channels and two digital channels

I have not seen the same modification on the description of the QUAD in the depot

Is there some problem with the analog chain?

There is also (but it is an old one) this difference between the garden
Accesories within Pack 2 mcx osilloscope probe, 2 mcx digital probe
and the depot
Accesories within Pack 2 mcx osilloscope probe, 1 mcx digital probe

Who’s right?

I am sorry that my modification make you confused, Actully, it is 36MS/s+36MS/s for the 2 analog channel, also, If configured to single channel, The sample rate is 72MS/s…
And, We plan to overclock the ADC:AD9288-40, If successed, The sample rate can be 72MS/s+72MS/s, That is, Sample rate can be 144MS/s if configured to single channel.
