Description Select the specified channel as the current channel and set the voltage/current of
this channel.
Set the voltage/current of the current channel.
Query the voltage/current of the specified channel.
Parameter Name Type Range Default
{CH1|CH2|CH3} [1] Discrete CH1|CH2|CH3 None
Real Refer to Table 2-1
Real Refer to Table 2-1
[CH1|CH2|CH3] Discrete CH1|CH2|CH3 None
[CURRent|VOLTage] Discrete CURRent|VOLTage None
Explanation  For the multi-channel models, this command is used to select the specified
channel and set the voltage and current; for the single-channel model, this
command is used to set the voltage and current of the channel. This command
combines the channel select command
( :INSTrument:NSELect , :INSTrument[:SELEct] or :INSTrument[:SELect] , only
applicable to the multi-channel models), voltage setting command
( [:SOURce[]]:VOLTage[:LEVel][:IMMediate][:AMPLitude] ) and current
setting command
( [:SOURce[]]:CURRent[:LEVel][:IMMediate][:AMPLitude] ) functions.
 In the query command, the parameter [CH1|CH2|CH3] is used to select the
channel to be query. If it is ignored, the current channel will be query.
 and are used to set the voltage and current of the specified
channel respectively. If only one parameter is specified, the value is the
voltage setting value by default; if both of them are omitted, the command will
select the desired channel. The voltage/current ranges of each channel (range)
of different models are as shown in Table 2-1.
 You can use MINimum, MAXimum or DEF which denote setting the voltage or
current of the specified channel (range) to the minimum, maximum or default
instead of the specified voltage () or current value (). The
voltage/current ranges of each channel (range) of different models are as
shown in Table 2-1.
 [CURRent|VOLTage] is used to select to query the voltage or current of the
specified channel. If they are both omitted, the system will query both the
voltage and current of the specified channel.
 In the query command, you can omit both of the parameters or only omit
[CURRent|VOLTage]; but you cannot only omit [CH1|CH2|CH3].
Return Format The query returns a string.
 The query returns the voltage or current setting value of the specified channel
when [CH1|CH2|CH3] and [CURRent|VOLTage] are specified, for example,
5.000.
 The query returns the channel (range) name, rated voltage/current value,
voltage setting value and current setting value of the specified channel
