TRIGger:CH<x>:CLKRec:LIST? (Query Only)
This query returns a list of the clock recovery selections that are available for
the channel speci
fi ed by x, which can be 1 through 4. The available choices are
dependent on the optical sampling or accessory module that is installed.
The optical modules have differing valid settings. Use this query to determine
the valid {Clock Recovery | Filter | Bandwidth | Wavelength} settings for your
optical module. Features of optical modules are listed in their respective user
manuals. Features of currently installed optical modules can be viewed using
the System Properties dialog.

TRIGger:CH<x>:CLKRec:RANge? (Query Only)
This query returns the allowable range for a User (custom) clock rate as
<NR3>-<NR3> for the channel speci
fi ed by X, which can be 1 through 4. (The
available choices for X are dependent on the sampling module that is installed.)
The channel speci
fi ed must be from a sampling module that provides continuous
clock-recovery capability in order to return a range; otherwise, "NONE" is
returned.
The allowable range is the range supported by the module of the speci fi ed channel.
Use the range returned values of this query to set the User clock rate with the
TRIGger:CH<x>:CLKRec:USEr command.
