16-4 Common Commands 2400 Series SourceMeter
®
User’s Manual
Use the *SAV command to save the present instrument setup configuration in
memory for later recall. Any control affected by *RST can be saved by the *SAV
command. The *RCL command is used to restore the instrument to the saved
setup configuration. Five setup configurations can be saved and recalled.
The SourceMeter ships from the factory with SYSTem:PRESet defaults loaded
into the available setup memory. If a recall error occurs, the setup memory
defaults to the
SYSTem:PRESet values.
**RST — reset
When the *RST command is sent, the
SourceMeter performs the following operations:
• Returns the SourceMeter to the GPIB default conditions (see “Default” col-
umn of SCPI tables in Section 18).
• Cancels all pending commands.
• Cancels response to any previously received *OPC and *OPC? com-
mands.
*TRG — trigger
Use the *TRG command to issue a
GPIB trigger to the SourceMeter. It has the same effect as a group execute trigger
(GET).
Use the *TRG command as an event to control operation. The SourceMeter
reacts to this trigger if BUS is the programmed arm control source. The control
source is programmed from the TRIGger subsystem.
NOTE Details on triggering are covered in Section 11.
**TST? — self-test query
Use this query command to perform a
checksum test on ROM. The command places the coded result (0 or 1) in the Out-
put Queue. When the SourceMeter is addressed to talk, the coded result is sent
from the Output Queue to the computer.
A returned value of zero (0) indicates that the test passed, and a value of one (1)
indicates that the test failed.
