CURVEStream
This query continuously transfers waveform data from the instrument as it is
acquired. This command puts the instrument into a talk-only mode, allowing
the controller to receive waveform records as fast as (and as soon as) they are
acquired. Use the DATa:SOUrce command to specify the waveform sources. The
command does the same thing as the CURVe command.
Control of the instrument through the user interface or other external client is
not possible while in streaming mode.
The GPIB controller must take the instrument out of this c ontinuous talking
mode to terminate the query and allow other input sources to resume
communication with the instrument. The following options are available to
transition out of streaming curve mode: send a device clear over the bus or
send another query to the instrument (a MEPE Query Interrupted error will
occur, but the instrument will be placed back into its normal talk/listen mode).
Turning the waveform screen display mode off (:DISplay:WAVEform OFF)
will increase waveform throughput during streaming mode.
While in streaming mode, two extreme conditions can occur. If the waveform
records are being acquired slowly (high resolution), configure the controller
for long time-out thresholds, as the data is not sent out until each complete
record is acquired. If the waveform re cords are being acquired rapidly (low
resolution), and the controller is not reading the data off the bus fast enough,
the trigger rate is slowed to allow each waveform to be sent sequentially.
