Command Reference
LOP?
The LOP? query command returns the operation status of all modules and stores the
results in the output data buffer (query buffer).
LOP?
For E5262A/E5263A:
LOPstat1,stat2 <CR/LF^EOI>
For E5260A/E5270B:
LOPstat1,stat2,stat3,stat4,stat5,stat6,stat7,stat8 <CR/LF^EOI>
The variables stat1 to stat8 will indicate the status of the module installed in the slot
1 to 8 respectively, and will be the two-digit status code shown in the following
table. For the HPSMU that occupies two slots, two variables will be returned. Then
the first one is always 00, and the last one indicates the module status. For example,
LOP00,11,00,00,00,00,00,00 will be returned when only the HPSMU
installed in the slot 1-2 is used and is in the voltage compliance condition.
Status
code
00 No module is installed, or the output switch is OFF.
01 SMU forces voltage, and does not reach current compliance.
02 SMU forces positive current, and does not reach voltage compliance.
03 SMU forces negative current, and does not reach voltage compliance.
10 Not applicable.
11 SMU reaches voltage compliance.
12 SMU reaches positive current compliance.
13 SMU reaches negative current compliance.
20 SMU is oscillating.
30 Not applicable.
