Commands Listed in Alphabetical Order
Examples DATA:SOURCE? might return :DATA:SOURCE REF3 indicating that the source for
the waveform data which is transferred using a CURVe? query is reference 3.
DATA:SOURCE CH1 specifies that the CH1 waveform will be transferred in the
next CURVe? query.
DATa:STARt
Sets or returns the starting data point for incoming or outgoing waveform transfer.
This command allows for the transfer of partial waveforms to and from the
oscilloscope.

Arguments <NR1> is the first data point that will be transferred, which ranges from 1 to the
record length. Data will be transferred from <NR1> to DATa:STOPor the record
length, whichever is less. If <NR1> is greater than the record length, the last
data point in the record is transferred.
DATa:STARt and DATa:STOP are order independent. When DATa:STOP is
greater than DATa:STARt, the values will be swapped internally for the CURVE?
query.
Examples DATA:START? might return :DATA:START 214 indicating that data point 214 is
the first waveform data point that will be transferred.
DATA:START 10 specifies that the waveform transfer will begin with data point 10.
DATa:STOP
Sets or returns the last data point that will be transferred when using the CURVe?
query. This command allows for the transfer of partial waveforms from the
oscilloscope.
Changes to the record length value are not automatically reflectedinthe
DATa:STOP value. As record length is varied, the DATa:STO P value must be
explicitly changed to ensure the entire record is transmitted. In other words, curve
results will not automatically and correctly reflect increases in record length if
