Query the data of all traces at once

Description

I have several traces and I want to query the data of all traces.
At first I have to set the trace "active" - then it is possible to query the data of just that trace.
This is time consuming and cumbersome.

Is there a way to query the data of all traces at once?

Resolution

That is possible if one condition is fulfilled:
All traces must belong to the same channel.

Use the command:
"CALC:DATA:ALL? SDAT"
The trace data will come one by one without seperation. The amount of data per sweep point depends from the format setting of the trace.
