SCPI Command Reference 17-77
:POINts?
:SOURce[1]:LIST:CURRent:POINts? Query length of I-Source list
:SOURce[1]:LIST:VOLTage:POINts? Query length of V-Source list
Description This command is used to determine the length of the specified source list.
The response message indicates the number of source values in the list.
Configure memory sweep
A memory sweep lets you perform a sweep using setups stored in up to 100 memory loca-
tions. This allows you to sweep using multiple source-measure operations and math expres-
sions. See CALCulate1.
NOTE In order to run a memory sweep, the memory function must be selected, and the trig-
ger count must be the same as the number of memory points in the sweep. Use the
:FUNCtion:MODE command to select the MEMory function. See “Select function
mode.” Arm count (ARM:COUNt) and trigger count (TRIGger:COUNt) are set from
the Trigger Subsystem.
When memory is initialized (:SYSTem:MEMory:INITialize), all 100 memory loca-
tions for a memory sweep are initialized to the present setup configuration of the
SourceMeter with CALC 1 disabled. User-defined math expressions are replaced
with the “Power” math expression.
Error 809 “Source memory location revised” occurs when a memory sweep refer-
ences an expression that no longer exists. The memory sweep is revised to disable
CALC1.
In order to execute a memory sweep, the product of the arm count and trigger count
should be at least the same as the number of points in the sweep.
Use the :FUNCtion:MODE command to select the MEMory function. See Select function
mode. Arm count (ARM:COUNt) and trigger count (TRIGger:COUNt) are set from the Trigger
Subsystem.
:SAVE <NRf>
:SOURce[1]:MEMory:SAVE <NRf> Save setup in specified memory location
Parameters <NRf> = 1 to 100 Specify memory location
Description This command is used to save the present instrument setup in a memory
location. Up to 100 setups can be saved. The following settings are saved in
each source memory location:
SENSe[1]:CURRent:NPLCycles
SENSe[1]:RESistance:NPLCycles
SENSe[1]:VOLTage:NPLCycles
SENSe[1]:FUNCtion:CONCurrent
SENSe[1]:FUNCtion:ON
SENSe[1]:FUNCtion:OFF
