CH<x>:BANdwid
th {TWEnty |TWOfifty|FULl| <NR3>}
CH<x>:BANdwidth?
Arguments
TWEnty sets the upper bandwidth limit of channel <x> to 20 MHz.
TWOfifty se
ts the upper bandwidth limit of channel <x> to 250 MHz.
FULl disables any optional b andwidth limiting. The specified channel operates
at its maxim
um attainable bandwidth.
<NR3> is a double-precision ASCII string. The oscilloscope rounds this value to
an availab
le 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 o
r returns the input attenuator coupling setting for channel <x>, where x
is the channel number.

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.
