Parameters 0 = Memory location 0
1 = Memory location 1
2 = Memory location 2
3 = Memory location 3
4 = Memory location 4
NOTE For the Models 2306-PJ and 2306-VS, the memory location settings available are
fr
om *SAV 0 -*SAV 2 and *RCL 0 -*RCL 2 (*SAV 3 and *SAV 4, and *RCL 3 and
*RCL 4 are not available).
Use the *SAV command to save the present instrument setup configuration in memory for
later rec
all. 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. *SAV and *RCL are global commands (not channel
