Common Commands
C) SAV <NRf> — save
Parameters
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. Three setup
configurations can be saved and recalled.
The Model 6487 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.
Programming example:
*SAV 2
*RST
*RCL 2
D) RST — reset
When the *RST command is sent, the Model 6487 performs the following operations:
1.
2.
3.
E) TRG — trigger
Use the *TRG command to issue a GPIB trigger to the Model 6487. It has the same effect
as a group execute trigger (GET).
Use the *TRG command as an event to control operation. The Model 6487 reacts to this
trigger if BUS is the programmed arm control source. The control source is programmed
from the TRIGger subsystem.

Programming example — The following command sequence configures the Model 6487
to be controlled by bus triggers. The last line, which sends a bus trigger, triggers one mea-
surement. Each subsequent bus trigger will also trigger a single measurement.
*RST
ARM:SOUR BUS
ARM:COUN INF
INIT
*TRG
RCL <NRf> — recall
0 = Memory location 0
1 = Memory location 1
2 = Memory location 2
' Save present setup in memory location 2.
' Set 6487 to RST defaults.
' Return (recall) 6487 to setup stored in memory location 2.
Returns Model 6487 to the RST default conditions (see "Default" column of SCPI
tables).
Cancels all pending commands.
Cancels response to any previously received *OPC and *OPC? commands.
