Where,
Character 1 (49) is equal to ON.
Character 0 (48) is equal to OFF.
For example: WrtCmd (“BIAS:STATe 0”) Set the DC bias function as OFF.
Query syntax: BIAS:STATe?
Return format: <NR1><NL^END>
The BIAS:VOLTage command is used to set the internal bias voltage. The
BIAS:VOLTage? query returns the current bias voltage.
Command syntax:
<value>
BIAS:VOLTage MIN
MAX
Where,
<value> NR1, NR2 or NR3 data format.
MIN Set the bias voltage as 0V.
MAX Set the bias voltage as 5V.
For example: WrtCmd (“BIAS:VOLT MIN”) Set the DC bias voltage as 0V.
Query syntax: BIAS:VOLTage?
Return format: <NR3><NL^END>
The BIAS:CURRent command is used to set the external bias current. The
BIAS:CURRent? query returns the bias current. The external bias current is
controlled by serial interface, so only GPIB interface supports this command.
Command syntax:
<value>
BIAS:CURRent MIN
MAX
Where,
<value> NR1, NR2 or NR3 data format
MIN Set the bias current as 0A.
MAX Set the bias current as 50mA.
For example: WrtCmd (“BIAS:CURR MIN”) Set the DC bias current as 0A.
Query syntax: BIAS:CURRent?
Return format: <NR3><NL^END>
(NOTE: when the internal resistance is 30
Ω
, the range of bias voltage is
±
1.5V and the range of bias current is
±
100mA; when the internal
resistance is 100
Ω
, the range of bias voltage is
±
5V and the range of
bias current is
±
50mA.)
