Where,
<value> is NR1, NR2 or NR3 data format.
For example: WrtCmd (“LIST:CURR 100MA”) Set the measurement current of
the sweep point 1 as 100mA.
WrtCmd (“LIST:CURR 1E-2, 2E-2, 3E-2, 4E-2”) Set the currents of
sweep points 1, 2,3 and 4 respectively as 10mA, 20mA, 3mA and 4mA.
NOTE: This command can be followed by a suffix unit A (ampere).
Query syntax: LIST:CURRent?
Return format: <NR3>[,<NR3>*]<NL^END>
NOTE: The current of each sweep point should be set from 50
μ
A to 20mA,
or return format will report errors.
The LIST:BIAS:VOLTage command is used to clear the original DC bias voltage of
each sweep point and reset the voltage. The LIST:BIAS:VOLTage? query returns
the current DC bias voltage of each sweep point.
Command syntax: LIST:BIAS:VOLTage<value>[,<value>*]
NOTE: * part means 10 sweep points at most can be set.
Where,
<value> is NR1, NR2 or NR3 data format.
For example: WrtCmd (“LIST:BIAS:VOLT 1.5V”)
Set the DC bias voltage of sweep point 1 as 1.5V.
Query syntax: LIST:BIAS
：
VOLTage?
Return format: <NR3>[,<NR3>*]<NL^END>
The LIST:BIAS:CURRent command is used to clear the original DC bias current of
each sweep point and reset them. The LIST:BIAS:CURRent? query returns the the
DC bias current of each sweep point.
Command syntax: LIST:BIAS:CURRent<value>[,<value>*]
NOTE: * part means 10 sweep points at most can be set.
Where,
<value> is NR1, NR2 or NR3 data format.
For example: WrtCmd (“LIST:BIAS:CURR 100MA”) Set the DC bias current of
the sweep point 1 as 100mA.
WrtCmd (“LIST:BIAS:CURR 1E-2, 2E-2, 3E-2,4E-2”) Set the DC
bias currents of sweep points 1, 2, 3 and 4 respectively as 10mA, 20mA, 30mA
and 40mA.
Query syntax: LIST:BIAS:CURRent?
Return format: <NR3>[,<NR3>*]<NL^END>
NOTE: U2829 series instrument has installed a 10V/100mA internal DC
bias current source. If 1A DC source is required, please install an
external source. U2829 can be used with TH1773 DC Bias Source
(providing DC current from 0 to 10A and can be bought from our
