Remote Interface Operation

FUNCtion:RAMP:SYMMetry <percent>

The APPLy command automatically sets the symmetry to 100%.

Output Control

You can disable or enable the soft front panel output control. By default, the output is disabled at power-on. When

enabled, the Output button is illuminated.

If an excessive external voltage is applied to the device output connector, the output will be disabled. To re-enable the output, remove the overload from the output connector

and click Output to enable the output.

Soft Front Panel Operation

Click Output to enable or disable the output as shown in Figure 2- 11.
