5.6 CHANnel Group
:CHANnel<x>?
Function
Queries all vertical axis settings of a channel.
Syntax
:CHANnel<x>?
<x> = 1 to 8
:CHANnel<x>:ASCale[:EXECute]
Function
Executes auto scaling of a channel.
Syntax
CHANnel<x>:ASCale[:EXECute]
<x> = 1 to 8
Example
CHANNEL1:ASCALE:EXECUTE
Description Auto scaling is possible on each channel.
• V/div
Displayed so that the entire amplitude of the
waveform can be seen without changing the
vertical position.
• Offset
When the input coupling is set to AC
0 V
When the input coupling is set to DC
Center = (Max+Min)/2
• Trig Level
DC offset position
:CHANnel<x>:BWIDth
Function
Sets or queries the input filter setting of a
channel.
Syntax
:CHANnel<x>:BWIDth {FULL|
<Frequency>}
:CHANnel<x>:BWIDth?
<x> = 1 to 8
<Frequency> = See the DLM4000 Features
Guide for this information.
Example
:CHANNEL1:BWIDTH FULL
:CHANNEL1:BWIDTH?
-> :CHANNEL1:BWIDTH FULL
:CHANnel<x>:COUPling
Function
Sets or queries the input coupling setting of a
channel.
Syntax
