TRACE:COPY
TRACe:POINts?
Returns the number of sample points in the acquisition record or CALCulate
block record. The record length is set differently for each source:
H CHAN<n> is set by SWEep:POINts.
H AATS (Auto-advance Time Stamp) is set by AADVance:COUNt.
H CALC<n> depends on the record length of the source waveform(s) and the
measurement or calculation selected.
H Auto Advance is set by AADVance:RECord:STARt and AADVance:RE-
Cord:COUNt.
H The query does not return until pending acquisitions/calculations are
complete. No *WAI, *OPC, or *OPC? is required unless the user wishes to
synchronize in a different manner.
H The record length of a CHANn trace depends on the value of
SWEep:POINts.
H The record length of the AATS trace depends on the value of SWEep:AAD-
Vance:COUNt.
H The record length of a CALCn trace depends on the the record length of the
source waveform(s) and the measurement being performed.
H The record length of a REFn trace depends on the record length of the stored
data.
H If Auto Advance is on, the AADVance:RECord:STARt and :COUNt
commands determine the number of points returned by this query.
H If a trace contains no valid data, a length of zero is returned. No error is
generated.
H There is no associated command for this query.
If the record contains no data, a length of zero is returned.
