10.6 Limit Subsystem
This subsystem controls the voltage frequency and current limit of the power source. These
limits are set at the factory and depend on the power source rating. It is not accessible by
the user. The query format is accessible however.
Subsystem Syntax
LIMit:
CURRent?
Queries the upper current limit
FREQuency:
LOW?
Queries the lower frequency limit
HIGH? Queries the upper frequency limit
VOLTage? Queries the upper voltage limit
LIMit:CURRent?
This command queries the maximum current limit the power source will operate at in the low
voltage range.
Command Syntax LIMit:CURRent <NRf>
Parameters maximum current limit at low voltage range [command
protected]
Query Syntax LIMit:CURRent?
Returned Parameters <NR2>
LIMit:FREQuency:LOW?
This command queries the lower frequency limit of the power source. On the 2001RP-AV,
the frequency range may have been factory configured to a fixed single value. In this case,
the High and Low frequency limits will be set to the same value and both queries will return
the same number. Sending a frequency command with any value other than the set value
will result in a “-100, Command Error”.
Command Syntax LIMit:FREQuency:LOW <NRf>
Parameters Low freq limit [command protected]
Query Syntax LIMit:FREQuency:LOW?
Returned Parameters <NR2>
LIMit:FREQuency:HIGH?
This command queries the upper frequency limit of the power source. On the 2001RP-AV,
the frequency range may have been factory configured to a fixed single value. In this case,
the High and Low frequency limits will be set to the same value and both queries will return
the same number. Sending a frequency command with any value other than the set value
will result in a “-100, Command Error”.
Command Syntax LIMit:FREQuency:HIGH <NRf>
Parameters High freq limit [command protected]
Query Syntax LIMit:FREQuency:HIGH?
Returned Parameters <NR2>
