Table A-2: Special characters
|
A vertical stroke in parameter definitions indicates alternative possibilities in the sense of "or". The
effect of the command differs, depending on the used parameter.
Example:
●
FUSE:LINK {1 | 2 | 3}
●
FUSE:LINK 1
sets the fuse link CH1 for the selected channel
FUSE:LINK 2
sets the fuse
link of CH2 for the selected channel
[ ]
Mnemonics in square brackets are optional and can be inserted into the header or be omitted.
Example:
●
FUSE[:STATe] { ON }
●
FUSE:STAT ON
is equivalent to
FUSE ON
{ }
Parameters in curly brackets are optional and can be inserted once or several times, or be omitted.
Example:
●
VOLTage[:LEVel][:IMMediate][:AMPLitude] {<voltage> | MIN | MAX | UP |
DOWN }
The following are valid commands:
–
VOLT MAX
–
VOLT MIN VOLT 10
Syntax for Channel List Commands
For demonstration purposes only, assume the existence of the following commands for
this section:
●
VOLT? (@2)
●
OUTP (@2)
●
VOLT? (@1,3)
●
VOLT? (@1:4)
●
VOLT 5, (@1:4)
When adding a channel list parameter to a query, there must be a space character
between the query indicator (?) and the channel list parameter. Otherwise an error
-103, invalid separator occurs.
Table A-3: Special characters
@
The "
@
" sign in parameter definitions indicates in the sense of "at", this is part of the channel list
command syntax.
Example:
●
VOLT? (@2)
queries the voltage at CH2
●
OUTP 1, (@3)
turns on the output at CH3
,
The comma sign in parameter definitions indicates in the sense of seperator for additional chan-
nels defination.
Example:
●
VOLT? (@1,3)
queries the voltage at CH1 and CH3
●
VOLT? (@1,3,4)
is equivalent to queries the voltage at CH1, CH3 and CH4
:
The colon sign in parameter definitions indicates the defination of of channel range for additional
channel defination.
Example:
●
VOLTage? (@1:3)
queries the voltage at CH1, CH2, CH3
●
VOLTage 5, (@1:3)
configures CH1, CH2 and CH3 to 5 V
