The Input Coupling and Minimum Frequency are common
settings that apply to both channels.
The Input Coupling control connects or separates input channel
1 and 2. If Common is set, the signal at channel 1 is connected
to both channels.
The Minimum Frequency control sets the minimum frequency of
the auto trigger algorithm. This can be 50Hz or 1000Hz.
The Apply command button invokes the changes to the
settings. The Default command button initializes the controls to
the power-up settings, but does not invoke the changes unless
Apply is subsequently operated. The Cancel button closes the
soft front panel ignoring any change made to the settings.
