CALCulate:DATA:PREamble?
Description
Reads the spectrum data preamble. The preamble information is valid only spectrum data
from the same single spectrum calculation initiated by
CALCulate:TRANsform:FREQuency[:STATe] ONCE.
If this query is sent during a harmonics measurement (STATus:OPERation bit 12 is set)
an error "-230, Data corrupt or stale" is generated and no preamble data is returned.
Response
<start_time>,<line_count>,<function_count>,<freq>[,<freq>,…]
<start_time> Indicates time interval between the TIMer:RESet:TIME? and first point of
the sampled data that was used in the most recent spectrum calculation. If a harmonics
measurement has not yet been performed ASCII equivalent of NaN (+9.91E+37) is
returned for this item.
<line_count> Indicates number of spectrum lines calculated per function
<function_count> Indicates number of functions in the spectrum function list.
<freq>[,<freq>,…] Is a list that contains frequency steps (FFT) or fundamental
frequencies (DFT) for each function in the spectrum function list. First frequency
corresponds to the first function in the function list, second frequency corresponds to the
second function in the function list, etc.
