the “local” key.
SYSTem:KLOCk:EXCLude?
Query which key is excluded when locking the front panel keyboard.
SYSTem:SECurity:IMMediate
Clears all instrument memory except for the boot parameters and calibration
constants. Reset all instrument setting to their *RST values. This command
clears all user-defined state information, user-defined arbitrary waveforms, and
user-defined I/O settings. This command is usually used to clear all memory for
security purpose, therefore it is not recommended for use in routine applications
because of the possibility of unintended loss of data.

TRIGger
Issue an immediate trigger from the remote interface. This command can
trigger a sweep or burst with any available trigger source (TRIG:SOUR
command).
TRIGger:SOURce {IMMediate︱EXTernal︱BUS}
Specify a trigger source for the triggered burst mode only. The waveform
generator accepts a software (BUS) trigger, an immediate (internal) trigger, or
a hardware trigger from the rear-panel EXT TRIG connector. The default is IMM.
z
When using the Immediate (internal) source, the frequency at which the
burst is generated is determined by the burst period.
z
When using the External source, the waveform generator takes hardware
trigger from the Trig In connector on the rear panel.
z
When using the Bus (software) trigger source, the waveform generator
outputs one burst each time it receives a bus trigger command. Use *TRG
to trigger from the remote interface. The Trigger button is lit when the
waveform generator is waiting for a trigger.
z
The APPLY automatically sets the trigger source to be Immediate.
z
When the External or the Bus source is selected, the burst count and the
burst phase remain in effect, but the burst period is ignored.
z
To ensure synchronization when the Bus source is selected, send the *WAI
(wait) command. When the *WAI command is executed, the waveform
