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 201 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: TH2829 instrument has installed a 10V/100mA internal DC bias
current source. If 1A DC source is required, please install an external
source. The instrument can be used with TH1778 DC Bias Source
(providing DC current from 0 to 20A and can be bought from our
company).
The LIST:MODE command is used to set the list sweep mode. The LIST:MODE?
query returns the current list sweep mode.
Command syntax:
SEQuence
LIST:MODE STEPped
Where,
SEQuence means sequential mode.
STEPped means single step mode.
For example: WrtCmd (“LIST:MODE SEQ”)
Query syntax: LIST:MODE?
Return format:
SEQ <NL^END>
STEP
The LIST:BAND<n> command is used to set the limits of list sweep table. The
LIST:BAND<n>? query returns the current limits.
Command syntax: LIST:BAND<n><parameter>[,<low limit n>,<high limit n>]
Where,
<n> 1 to 10 (NR1 format): sweep points on the n
th
line
<parameter> A Compare the primary parameter of the test results with the
high and the low limits.
