Initialize memory
INITialize
:SYSTem:MEMory:INITialize Initializes battery backed RAM
Description When this command is used, the following actions to initialize battery
backed RAM occur:
TRACe (data store) data is lost, buffer size is reset to 100, and
timestamp is set to the absolute format.
SOURce1:LIST:CURR and VOLT are reset to 0A and 0V,
respectively.
Deletes all user-defined math expressions. (See “CALCulate[1]
subsystem.)
All 100 memory locations for a memory sweep are initialized to
the present setup configuration of the SourceMeter with CALC 1
disabled. User-defined math expressions are replaced with the
“Power” math expression.
The four standard save setups (*SAV0 - *SAV4) are initialized to
the present setup configuration of the SourceMeter.
All CALCulate1 user-defined math expressions are deleted.
Control beeper
[:IMMediate] <freq, time>
:SYSTem:BEEPer[:IMMediate] <freq, time>
Parameters freq = 65 to 2e6 Specify frequency in Hz
time = 0 to 7.9 Specify time duration
NOTE The frequency and time values must be separated by a comma (i.e.,
:syst:beep 100,
3).
Description The beeper of the SourceMeter can be used to provide an audible
signal at a specified frequency and time duration (up to 7.9 seconds
@ 65Hz). This beeper can, for example, be used to signal the end of
a lengthy sweep.
Example: :SYSTem:BEEPer500, 1 Beep at 500Hz for 1 second
The correlation between the duration and frequency of the beep is
expressed as follows:
Maximum Time = 512/ Frequency
For example, at a frequency of 512Hz, the maximum beep time is
one second. You can set the time greater than one (1) second, but it
will only beep for one second.
Note that in order to use this command, the beeper must be enabled.
(See next command.)
