CV Output
Requirement
Use the SCPI commands to realize the following functions:
CH1 CV output; set the output voltage to 5V, the output current to 5A and the overcurrent protection limit to
5.3A.
Method 1
1 *IDN? /*Query the ID character string of the power supply to check whether the
remote communication is normal*/
2 :INST CH1 /*Select CH1*/
3 :CURR 5 /*Set the current to 5A*/
4 :CURR:PROT 5.3 /*Set the overcurrent protection limit of CH1 to 5.3A*/
5 :CURR:PROT:STAT ON /*Enable the overcurrent protection function of CH1*/
6 :VOLT 5 /*Set the voltage to 5V*/
7 :OUTP CH1,ON /*Enable the output of CH1*/
Method 2
1 *IDN? /*Query the ID character string of the power supply to check whether the
remote communication is normal*/
2 :CURR:PROT 5.3 /*Set the overcurrent protection limit of CH1 to 5.3A*/
3 :CURR:PROT:STAT ON /*Enable the overcurrent protection function of CH1*/
4 :APPL CH1,5,5 /*Select CH1, set the voltage to 5V and current to 5A*/
5 :OUTP CH1,ON /*Enable the output of CH1*/
Track Function
Some channels of DP800 support the track function, including CH2 and CH3 of DP831A as well as CH1 and
CH2 of DP832A/DP832.
Requirement
Use the SCPI commands to realize the following functions by taking DP831A as an example:
Enable the track function of CH3; change the voltage setting value of CH3 from -5V to -30V; at this point,
the voltage setting value of CH2 changes accordingly.
Method
1 *IDN? /*Query the ID character string of the power supply to check whether the
remote communication is normal*/
2 :OUTP:TRAC CH3,ON /*Enable the track function of CH3*/
3 :APPL CH3,-5,1 /*Set the voltage of CH3 to -5V and the current to 1A*/
4 :APPLy? CH2,VOLTage /*Query the voltage of CH2 and the query returns 5.000*/
5 :APPL CH3,-30,1 /*Change the voltage of CH3 to -30V*/
6 :APPLy? CH2,VOLTage /*Query the voltage of CH2 and the query returns 30.000*/
