Uploading Captured Data from a Channel
The commands described in this section are related to uploading binary capture data
from the instrument. Text commands are sent through
the control port and binary data
is sent through
the data port. Each binary data sample is contained in a 16-bit word for
I (In-Phase component) followed by a 16-bit word for Q (Quadrature component).
There are 4096 I/Q pairs, for a total data capture size of 16,384 bytes.
Beginning the Capture Upload
Syntax:
Begin Capture Uptransfer
<channel>
Function:
Informs the instrument that uploading capture data will begin.
Returns:
Nak:
<error message>
or
Ack: Capture Uptransfer Beginning
Where:
<error message>
Descriptive text describing cause of error
<channel>
CH1/CH2/CH3/CH4
Notes:
The
Begin Capture Uptransfer
command is sent through the control
port of the instrument, and the acknowledgement or Nak comes through the
control port.
Receiving Binary Capture Data
Syntax:
Next Capture Uptransfer
Function:
Binary data segments are sent through the data port of the instrument.
Returns:
Nak:
<error message>
or
[binary data]
Where:
<error message>
Descriptive text describing cause of error
Notes:
The binary data is sent through
the data port as the acknowledgement or the
Nak comes through the control port.
The binary data size for each segment is limited to 8192 bytes.
