Commands Listed in Alphabetical Order
Arguments
INTERnal speci
fies to use the internal 10 MHz crystal oscillator as the time
base reference.
EXTernal specifies to use a user-supplied external signal as the time base
reference.
Examples
ROSC:SOURCE? might return INTERNAL, indicating that the 10 MHz crystal
oscillator is being used as the time base reference.
ROSc:STATE? (Query Only)
This query returns an enumeration value that indicates the lock state of the
reference oscillator specified by the
ROSc:SOUrce command. The values
returned are
LOCKED or UNLOCKED.

Syntax
*SAV <N R1>
Related Commands
*RCL, RECAll:SETUp,
SAVe:SETUp
Arguments
<NR1> specifies a location in which to save the state of the oscilloscope. Location
values range from 1 through 10. Using an out-of-range location value causesan
execution error. Any settings that have been stored previously at this location
will be overwritten.
Examples
*SAV 2 saves the current oscilloscope state in memory location 2.

Save and Recall
Syntax
SAVe:ASSIgn:TYPe {IMAGe|WAVEform|SETUp}
SAVe:ASSIgn:TYPe?
Arguments
IMAGe assigns the Save button to save screen images.
WAVEform assigns the Save button to save waveforms.
SETUp assigns the Save button to save setups.
SAVe:EVENTtable:{BUS<x>|B<x>} (No Query Form)
Saves the data from bus<x> to a specified file and location; where x is the bus
number (1-4). 1-3 for the MDO4000C and 1-2 for the MDO3000.
NOTE. External filestructureisasfollows:
E: is the USB memory device plugged into the first USB port o n the front of the
oscilloscope.
F: is the USB memory device plugged into the second USB port on the front of
the oscilloscope.
G: and H: are the USB memory device plugged into the USB ports on the rear o f
the oscilloscope.
I: is the network storage.
However, the MDO3000 only has two ports. E: is on the front and F: is on the rear.

Syntax
SAVe:EVENTtable:{BUS<x>|B<x>} <file path>
Arguments
<file p ath> is a quoted string that defines the file name and path location
where the event table will be stored.
