:MEMory Commands:
:SAVE M<num>
[:ROUTe]:MEMory:SAVE M<num> Save current channel pattern at specified memory location
<num> = a whole number from 1 to 100 Specify memory location
:mem:save M<num>
Power-up No effect
*RST No effect
:SYSTem PRESet No effect
This command is used to save (store) the current channel pattern at a memory location. For ex-
ample, if channels 1!1, 1!6, 1!8 and 2!5 are currently closed, you can save that channel pattern
to memory location 36. When M36 is later recalled or scanned, the four channels of that channel
pattern will close, and all other channels will open.
Up to 100 channel patterns can be saved in memory locations 1 to 100. A channel pattern can
be recalled from memory using the :RECall command.
A Channel Pattern is not lost (cleared) after the instrument is turned off. However, a Channel
Pattern is cleared if a closed channel in the pattern becomes unavailable or restricted.
OUTPUT 707; “:clos (@ 1!1:1!10)” ! Closes ch 1-10 of Slot 1
OUTPUT 707; “:mem:save M36” ! Saves pattern to M36
1st Line Closes channels 1-10 of Slot 1.
2nd Line Saves channel pattern to memory location 36.
:RECall M<num>
[:ROUTe]:MEMory:RECall M<NRf> Recall channel pattern from memory
<num> = 1 to 100 Specify memory location
:mem:rec M<num>
This command is used to recall a channel pattern stored at a memory location. Channel patterns
can be recalled from memory locations 1 to 100. As soon as the channel pattern is recalled, chan-
