*CLS (No Query
Form)
Clears the following:
Event Queue
Standard Event Status Register
Status Byte Register (except the MAV bit)
If the *CLS
command immediately follows an <EOI>, the Output Queue and
MAV bit (Status Byte Register bit 4) are also cleared. The MAV bit indicates that
information is in the output queue. The device clear (DCL) control message
will clear the output queue and thus MAV. *CLS does not clear the output queue
o r M AV.
*CLS can suppress a Service Request that is to be generated by an *OPC. This
will happen if a single sequence acquisition operation is still being processed
when the *CLS command is executed.

CONFIGuratio
n:AFG? (Query Only)
Indicates whether or not the arbitrary function generator hardware is present, and
the arbitrary function generation feature is enabled.
Conditions
Available for MDO3000 and MDO4000C series models only.
Group
Configuration
Syntax
CONFIGuration:AFG?
Returns
1 indicates that the arbitrary function generator hardware is present and the AFG
feature is enabled.
0 indicates that either the arbitrary function generator hardware is not present,
or the feature is not enabled.
Examples
CONFIG:AFG? might return 1, indicating that the hardware is present and the
feature is enabled.
CONFIGuration:ANALOg:BANDWidth? (Query Only)
This query returns the bandwidth, in Hz, for the analog channels.

Syntax
CONFIGuration:ANALOg:BANDWidth?
Related Commands
(See page 2-29, Horizontal Command Group.)
Returns
<NR3>, which is a floating point number that represents the bandwidth, in hertz,
for the analog channels.
CONFIGuration:ANALOg:GNDCPLG? (Query Only)
This query returns a boolean value to indicate whether the ground coupling
feature for analog channels is present. As this feature is not supported on
MSO/DPO4000B, MDO4000/B/C or MDO3000 models, this query always
returns 0.
