form can be used to control the conversion and storage destination of data
measured during a scan. The SCPI relative channel specification syntax is:
( )
@cc(nn, nn, nn:nn)
where cc = card number, and
For the HP E1313/E1413, card number becomes the channel data modifier.
The value can range from 1 through 7. The value controls whether Engineering
Unit (EU) conversion is performed and the internal destination of the resulting
value. Table 4-1 explains the effect of the channel data modifier:
Table 4-1 Channel Data Modifiers
Channel Data
Modifier
1 Perform EU conversion and store result in both FIFO buffer
and Current Value Table (CVT).
2* Leave measurement as voltage and store result in both
FIFO and CVT.
3 Perform EU conversion and store result in CVT only.
4* Leave measurement as voltage and store in CVT only.
5 Perform EU conversion and store result in FIFO only.
6* Leave measurement as voltage and store in FIFO only.
7* Leave measurement as voltage and do not store result in
either FIFO or CVT. Use as dummy channel set.
* Limit checking is not performed for channels that are not converted to
engineering units.
Both the standard and relative channel specification modes can be mixed
within a scan list definition. For example:
ROUT:SEQ:DEF LIST1,(@100:115,6(00:15))
This command specifies that the readings taken on channels 0 through 15 are to
be converted into engineering units and stored in both the FIFO data buffer and
the Current Value Table (CVT). In addition, channels 0 through 15 are to be
read and the raw voltage values are to be added to the FIFO buffer. The FIFO
will contain 16 converted readings and 16 voltage readings. The CVT will
contain a converted reading for channels 0 through 15.
To scan channels 0 through 63, send EU converted readings to the FIFO,
and send voltage readings to the CVT:
ROUT:SEQ:DEF LIST1,(@5(00:63),4(00:63))
, the SCPI relative channel specification
nn = channel number.
