POINts?
:SOURce[1]:LIST:CURRent:POINts?
Query length of current list
Description
These commands are used to determine the length of the specified cur-
rent list. The response message indicates the number of source values in
the list.
WIDTh <NRf list>
:SOURce[1]:LIST:WIDTh <NRf list>
Define pulse width list
Parameters
<NRf list> = NRf, NRf … NRf
NRf =
500e-9 to 5e-3
Pulse width (seconds)
Query
:WIDTh?
Query pulse width list
Description
This command is used to define a list of pulse widths (up to 100) for the
list sourcing mode of operation. When operation is started, the instru-
ment will sequentially source each current pulse value in the list (see
“CURRent <NRf list>,” page 14-41
) with the programmed pulse width
” below). Each pulse width point in
the list corresponds to the equivalent point in the current and delay lists.
The following command shows the proper format for defining a list
using pulse width values of 10
µ
s, 30
µ
s, and 60
µ
s:
:SOURce[1]:LIST:WIDTh 10e-6, 30e-6, 60e-6
NOTE
If the width list is shorter than the current list, the last width value will be used
for all subsequent current list points. If the width is not programmed, a default
value of 500ns will be used, but the query will return 0.
APPend <NRf list>
:SOURce[1]:LIST:WIDTh:APPend <NRf list>
Add value(s) to pulse width list
Parameters
<NRf list> = NRf, NRf … NRf
NRf =
500e-9 to 5e-3
Pulse width (seconds)
Description
This command is used to add one or more values (up to 100) to a pulse
width list that already exists. The pulse width values are appended to the
end of the list. (By using multiple appended lists, up to 1000 points can
be in a list.)
POINts?
:SOURce[1]:LIST:WIDTh:POINts?
Query length of pulse width list
Description
These commands are used to determine the length of the specified pulse
width list. The response message indicates the number of pulse width
values in the list.
