Syntax CH<x>:BANdwidth {TWEnty|TWOfifty|FULl|<NR3>}
CH<x>:BANdwidth?
Arguments TWEnty sets the upper bandwidth limit of channel <x> to 20 MHz.
TWOfifty sets the upper bandwidth limit of channel <x> to 250 MHz.
FULl disables any optional bandwidth limiting. The specified channel operates
at its maximum attainable bandwidth.
<NR3> is a double-precision ASCII string. The oscilloscope rounds this value to
an available bandwidth using geometric rounding, and then uses this value to
set the upper bandwidth limit.
NOTE. Other values may be possible depending on the attached probes.
Examples CH1:BANDWIDTH TWENTY sets the bandwidth of channel 1 to 20 MHz.
CH<x>:COUPling
Sets or returns the input attenuator coupling setting for channel <x>, where x
is the channel number.
Group Ver tical
Syntax CH<x>:COUPling {AC|DC|GND}
CH<x>:COUPling?
Arguments AC sets channel <x> to AC coupling.
DC sets channel <x> to DC coupling.
GND sets channel<x> to ground. Only a flat, ground-level waveform will be
displayed.
Examples CH2:COUPLING GND sets channel 2 to ground.
CH3:COUPling? might return :CH3:COUPling DC indicating that channel 3
is set to DC coupling.
