Usage
:SYSTem:BEEPer[:IMMediate] <frequency>, <duration>
<frequency>
The frequency of the beep (20 Hz to 8000 Hz)
<duration>
The amount of time to play the tone (0.001 s to 100 s)
Details
You can use the beeper of the instrument to provide an audible signal at a specific frequency and
time duration. For example, you can use the beeper to signal the end of a lengthy sweep.
Using this function from a remote interface does not affect audible errors or key click settings that
were made from the 2470 front panel.
Example
:SYSTem:BEEPer 500, 1
Beep at 500 Hz for 1 s.

:SYSTem:BREakdown:PROTection
This command allows you to enable the breakdown protection in situations where the current may exceed the
programmed current or the limit current value due to a breakdown condition.

Turn breakdown protection on (not recommended):
ON
Details
In some tests, the limited bandwidth of the SMU may cause current to exceed either the programmed
current or the limit current value. To prevent this from occurring, you can turn on the breakdown
protection function. This adds a 500
Ω resistor in series with the SMU force lead. This resistor limits,
at a wide bandwidth, the breakdown current to a maximum value of V

/500.
