Controlling Data Destination: The relative form of the SCPI Channel List
syntax is used to control the destination of data from channels in the scan list.
See “Channel List (Relative Form)” on page 232 for a discussion of the syntax.
The value of the "Data Destination" digit controls the destination of the values
read from the specified channels in the following manner:
See “Channel List (Relative Form)” on page 232 for a discussion of the syntax.
The value of the "Data Destination" digit controls the destination of the values
read from the specified channels in the following manner:
Example Channel lists (same applies to On-board channels):
ROUT:SEQ:DEF (@1(10000:10931))
1st 128 remote Chs sent to CVT
ROUT:SEQ:DEF (@2(10000:10931))
1st 128 remote Chs sent to FIFO buffer
ROUT:SEQ:DEF (@3(10000:10931))
1st 128 remote Chs sent to CVT & FIFO
ROUT:SEQ:DEF (@0(10000:10931))
1st 128 remote Chs discarded
•
Relationship between Channel number and CVT location: There is a fixed
relationship between each possible channel number and the Current Value Table
location that the channel reading is sent to.
location that the channel reading is sent to.
Data Destination
Effect on Reading
1
Reading sent to Current Value Table (CVT)
2
Reading sent to FIFO Buffer
3
Reading sent to CVT and FIFO
0
Reading not recorded (neither CVT or FIFO)
