9.2.6 OUTPut subsystem commands
9.2.6.1 Bias source
 Description: Set the DC bias source of the instrument
Command systax:
:OUTP:HPOW?
:OUTP:HPOW <INT | OPT | EXT>
Parameter:
INT ---- Internal 100mA bias current source
OPT ---- Internal 2A bias current source
EXT ---- external bias current source
Example:
:OUTP:HPOW INT ----Set the internal 100mA bias current source
:OUTP:HPOW OPT ----Set the internal 2A bias current source
:OUTP:HPOW EXT ----Set the external bias current source
:OUTP:HPOW? ----Return to bias current source mode
9.2.6.2 DCI isolation
 Description: Set the DC isolation function switch of the instrument
Command systax:
:OUTP:DC:ISOL?
:OUTP:DC:ISOL <0|1|ON|OFF >
Parameter:
0|OFF ---- OFF
1|ON ---- ON
Example:
:OUTP:DC:ISOL 0 ----Turn off the DC isolation function
:OUTP:DC:ISOL 1 ----Turn on the DC isolation function
:OUTP:DC:ISOL? ----Returns the switch status of the DC isolation function
9.2.7 BIAS subsystem commands
The :BIAS subsystem commands are mainly used to set the internal bias voltage and the bias status.
