Unable to read out dataset of m samples

[felix.hoff]

Hi,

I want to read out a variable number of datapoints.
For this I used the function:

rp_s.tx_txt('ACQ:SOUR1:DATA:OLD? ' +str(m))
data = rp_s.rx_txt()

However this is not working and my program gets stuck.
Is there an error in the function?

Thanks!
