|
(Read-only) Returns the names of the configured and active DC sources for the specified channel. Use SYST:CONF:EDEV:CAT? to read a list of all configured external devices, including inactive devices. |
|
|
Parameters |
|
|
<ch> |
Any existing channel number. If unspecified, value is set to 1 |
|
Examples |
SOUR:DC:CAT? 'Returns the following... "AO1,AO2,MyDCSupply" 'AO1 and AO2 are PNA-X internal DC Sources |
|
Return Type |
String, Names are separated by commas. |
|
Not Applicable |
|
|
(Read-Write) Sets and returns the DC stimulus values per point to be sent from the specified DC source. This setting overrides the Start and Stop DC settings for the channel. Only the values that are set with this command can be read by this command. The read command does NOT read the values that are set using the Start and Stop settings. |
|
|
Parameters |
|
|
<ch> |
Any existing channel number. If unspecified, value is set to 1 |
|
<name[,port]> |
String. The name and port must EXACTLY match those in the DC Source Control dialog. name - DC Source Name. See note for specifying internal DC Sources. [port] - Optional. PNA port for DC Source data. This is equivalent to the <per port> setting in the DC Source Control dialog. If unspecified, data is applied to ALL ports. Important: When you specify a port for this command, it must also be included for ALL DC Source commands that have this optional [port] specifier. |
|
<data> |
The stimulus value array to be set. The size of the array should be equal to the sweep point number. |
|
Examples |
'Set 3 data points on the channel scpi.Execute "SENS:SWE:POIN 3" 'Enable DC Source output scpi.Execute "SOUR:DC:ENAB ON" 'Set AO1 state to be always ON (no port value) scpi.Execute "SOUR:DC:STATe 'AO1',ON" 'Set DC value for each data point scpi.Execute "SOUR:DC:DATA 'AO1',1,5,1" 'Read data back data = scpi.Execute ("SOUR:DC:DATA?

(Read-Write) Sets and returns the ON / Off state of all configured DC sources for the specified channel. This setting is the same as the checkbox at the top of the DC Source Control dialog. Individual DC sources must ALSO be enabled using SOUR:DC:STATe. Use SYST:CONF:EDEV:CAT? to read a list of all configured external devices. Use SOUR:DC:CAT? to read a list of ACTIVE configured DC source names |
