User`s manual

When downloading segment sequence data from the VXIbus data transfer bus, the
most significant 16 bits should be written to offset 34 decimal (22 hex) in the
Agilent E1445A’s A24 address space. The least significant 16 bits should be
written to offset 36 decimal (24 hex).

For waveform segments, the length, in terms of points, must be greater than or equal to 4 and
less than or equal to the defined waveform segment length. The current waveform segment
length is set to this length.
MINimum selects 4 points; MAXimum selects the defined waveform segment length.
For segment sequences, the length, in terms of points, must be greater than or equal to 1 and
less than or equal to the defined segment sequence length. The current segment sequence
length is set to this length.
MINimum selects 1 point; MAXimum selects the defined waveform segment or segment
sequence length.
Comments • The waveform segment or segment sequence must have been previously defined
(see the
[SOURce:]LIST[1][:SEGMent]:DEFine and
[SOURce:]LIST[1]:SSEQuence:DEFine commands).
• When downloading is complete, use the [SOURce:]ARBitrary:DOWNload:COMPlete
command to restore normal operation.
• No error checking is performed on downloaded data. Erratic operation may occur
if invalid data (length or format) is downloaded.
• Executable when Initiated: No
• Coupling Group: None
• Related Commands: [SOURce:]LIST[1] commands
• *RST Condition: Downloading disabled
