CH1:BANDWIDTH
:LIST?
might return CH1:BANDWIDTH:LIST
20.0000000000E+009,12.499 99974400E+009
, indicating the bandwidths
available for Channel 1.
CH<x>:BANdw
idth:VALue
This command sets or queries the b andwidth for the channel specified by x,
which can be 1 through 8. Sending the command is the equivalent to selecting
a bandwidt
h from the Bandwidth pulldown menu in the Signal Conditioning
section of the Vertical Setup dialog box for Optical. The available bandwidths are
determined by the optical sampling module.
The optical modules have differing valid settings. Use the <>:LIST? query to
determine the valid {Clock Recovery | Filter | Bandwidth | Wavelength} settings
foryouropticalmodule. Featuresofcurrently installed modules can be viewed
using the System Properties dialog.
You can use the CH<x>:BANdwidth:LIST? query to determine the available
bandwidths for the specified channel.

Syntax
CH<x>:BANdwidth:VALue <NR3>
CH<x>:BANdwidth:VALue?
Arguments
NR3 is the value of the bandwidth you want to set. Use the
CH<x>:BANdwidth:LIST? command to query the b andwidths available for the
specified channel. The instrument automatically selects the bandwidth nearest
to the input value.
Examples
CH1:BANDWIDTH:VALUE 2.0E+10 sets the Channel 1 bandwidth to 20 GHz.
CH2:BANDWIDTH:VALUE? might return CH2:BANDWIDTH:VALU E
12.49999974400E+009
, indicating that the bandwidth for Channel 2 is set
to 12.5 GHz.
CH<x>:DELay
This command sets or queries the delay time for the channel specified by x, which
can be 1 through 8. Sending this command is the equivalent to setting Delay in
the Vertical Setup dialog box for the selected channel. You can adjust delay to
add or s ubtract an independent, channel-based acquisition time delay to the delay
from the trigger point (the horizontal position) that is inherently common to the
