Time Subsystem - Chroma 63800 Series Operation & Programming Manual

Programmable AC/DC Electronic Load 63800 Series Operation & Programming Manual
Description: It sets SYNC mode. When SYNC sets as 1, it indicates the system uses line
sync to do synchronization. When SYNC sets as 0, it indicates the system uses the frequency
users set to do synchronization. This command is only operating in DC Rectified Mode.
Setting Syntax : [LOAD:]SYNC:DC
Setting Parameter : 0 | OFF, 1 | ON
Query Syntax : [LOAD:]SYNC:DC?
Response Parameter: 0 | 1
Example : SYNC:DC ON
[LOAD:]FREQ[:LEVel][:AMPLitude]:DC
Description: It sets frequency. When SYNC sets as 0, it indicates the system uses the
frequency users set to do synchronization. This command is only operating in DC Rectified
Mode.
Setting Syntax : [LOAD:]FREQ[:LEVel][:AMPLitude]:DC
Setting Parameter : <NR2>, Range: 40 ~ 440, Unit: Hz
Query Syntax : [LOAD:]FREQ[:LEVel][:AMPLitude]:DC?
Response Parameter: <NR2>
Example : FREQ:DC 100

[LOAD:]TIME:VCUT
Description : It sets the cutoff voltage. When the voltage is under the cut off voltage.
Setting Syntax : [LOAD:]TIME:VCUT
Setting Parameter : <NR2>, Range: 0 ~ 500.000,Unit: V
Query Syntax : [LOAD:]TIME:VCUT?
Response Parameter: <NR2>
Example : TIME:VCUT
