4.7 Limit Subsystem
These subsystem commands may be used to query the hardware limits (capabilities) of the AC
power source. These commands are protected and can only be used in query format.
Subsystem Syntax
LIMit
:CURRent Current limit setting
:FREQuency
:HIGH Frequency limit high
:LOW Frequency limit low
:PHASe Phase mode
:VOLTage
:HIGH Voltage limit high voltage range
:LOW Voltage limit low voltage range
LIMit:CURRent
Query form returns the configuration current limit. This value determines the maximum current
available from one amplifier in the low voltage range. Note that this is not the same as the
available current maximum current, which is a function of voltage range and phase mode. To
query the maximum available RMS current, use the CURR? MAX command.
Query Syntax LIMit:CURRent?
Returned Parameters
Examples LIM:CURR?
Related Commands CURR
LIMit:FREQuency:HIGH
Query form returns the maximum available output frequency. This value determines the maximum
frequency available using a sinusoidal waveform. Note that this is not the same as the available
maximum frequency, which is a function of the frequency harmonic content of the waveform. To
query the maximum available frequency, use the FREQ? MAX command.
Query Syntax LIMit:FREQuency:HIGH?
Returned Parameters
Examples LIM:FREQ:HIGH?
Related Commands LIM:FREQ:LOW?
LIMit:FREQuency:LOW
Query form returns the maximum available output frequency. This value determines the minimum
frequency available.
Query Syntax LIMit:FREQuency:LOW?
Returned Parameters
Examples LIM:FREQ:LOW?
Related Commands LIM:FREQ:HIGH?
LIMit:PHASe
Query form returns the phase configuration setting. This value determines the phase mode of
operation according to the table below:
Setting Operation
0 Single-phase mode.
120 Three phase mode. Determines relative phase angle between phases A,
