Multichannel commands are particularly useful for configuring groups of devices that
require identical configurations.
The SCPI Commands for these instructions are:
[:]<root command> <ALL|addr1>[,[ ]<addr2>][,[
]<addr3>][,...]:<command> <parameter>
For example:
sour1, 2, 3, 7:volt 4.5
syst4,5,6:oper:enab 255
sourALL:volt 5
output0:stat on
Note: ALL and 0 do not work for query commands (i.e. SOUR:VOLT?,
MEAS:VOLT?, SOUR:CURR?, MEAS:CURR?)
STATUS REPORTING IN SCPI
The status reporting implemented in the power supply is primarily dictated by the SCPI
standard. This section provides a high level review of the standard status reporting
required by SCPI and then covers the specific reporting that is implemented within the
SCPI status reporting framework.
Figure 53 is taken from the SCPI 99 standard and shows the minimum status reporting
requirements for a SCPI compliant device.
Throughout this section, figures are used to explain the relationship between the
registers, enable/disabling register and their summary bits. The figures use four logical
symbols to demonstrate the relationship between the register. The “!” block represents
logical not or complement of the input signal. The “&” block represents the logical
AND operator. The “|” block represents the logical OR operation. The “+” block
represents the logical OR of all the bits from the enable register. The model has several
ellipses which are there to indicate that the pattern of logic shown is repeated for all bits
in the registers.
