As stated earlier, I'm collecting data traces from the PNA-X (using the CALC:DATA? FDATA) command. What I'm seeing is that if I set the number of data points high (like 16001 or 20001) I still only get 12501 points back (this number is constant). The data does cover the entire span specified (not like I'm getting data cropped). If I set the data points lower than 12501 (like 201/401/801/etc) I get that specific number of points back. Do I need to wait prior to performing the read after the CALC:DATA command or is there some sort of limit to the maximum number of data points returned (or am I missing a controlling command to allow for a big return)?
