Command Reference
*TST?
Parameters chnum : SMU or MFCMU channel number. Integer expression. 1 to 10. See
Table 4-1 on page 4-16.
If chnum is specified, this command clears the timer count once at the source output
start by the DV, DI, or DCV command for the specified channel. The channel output
switch of the specified channel must be ON when the timer count is cleared. This
command setting is disabled by the CL command. If multiple TSR chnum
commands are entered before timer clear, only the last command is effective.
If chnum is abbreviated, this command clears the timer count immediately.
Example
Statements
OUTPUT @B1500;"TSR"
OUTPUT @B1500;"TSR 1"
Remarks To read the time data with the best resolution (100 μs), the timer must be cleared
every 100 sec or less for the FMT1, 2, or 5 data output format, or
every 1000 sec or less for the FMT 11, 12, 15, 21, 22, or 25 data output format.
*TST?
This query command performs the self-test and self-calibration, and returns the
execution results. After this command, read the results soon.
Module condition after this command is the same as the condition by the CL
command.
Execution
Conditions
No SMU may be in the high voltage state (forcing more than the allowable voltage
for the interlock open condition, or voltage compliance set to more than it).
Before this command, open the measurement terminals.
