Model 2520 User’s Manual SCPI Command Reference 14-43
DELay <NRf list>
:SOURce[1]:LIST:DELay <NRf list> Define pulse delay list
Parameters
<NRf list> = NRf, NRf … NRf
NRf =
20e-6 to 0.5 Pulse delay (seconds)
Query
:DELay? Query pulse delay list
Description
This command is used to define a list of pulse delays (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
and delay. Each pulse delay point in the list corresponds to the equiva-
lent point in the current and width lists.
The following command shows the proper format for defining a list
using pulse delay values of 200
µ
s, 400
µ
s, and 500
µ
s:
:SOURce[1]:LIST:DELay 200e-6, 400e-6, 500e-6
NOTE
If the pulse delay list is shorter than the current list, the last pulse delay value
will be used for all subsequent current list points. If delay is not programmed, a
default value of 1.5ms will be used, but the query will return 0.
APPend <NRf list>
:SOURce[1]:LIST:DELay:APPend <NRf list> Add value(s) to pulse delay list
Parameters
<NRf list> = NRf, NRf … NRf
NRf =
20e-6 to 0.5 Pulse delay (seconds)
Description
This command is used to add one or more values (up to 100) to a pulse
delay list that already exists. The pulse delay 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:DELay:POINts? Query length of pulse delay list
Description
These commands are used to determine the length of the specified pulse
delay list. The response message indicates the number of pulse delay
values in the list.
