To set the calibration factors after replacing the acquisition board
The following procedure must be performed after replacing the acquisition board. This procedure only
needs to be performed once after the acquisition board is replaced.
Equipment Required
1
Perform self tests
a Exit the oscilloscope application.
b Right click on theAgilent Infiniium Application icon on the Desktop and select Properties. In
the Target field, enter the following string (note that -service is outside of the parentheses):
“c:\Program Files\Agilent\Infiniium\agscope.exe” -service. Then Press OK and double-click on
the Infiniium icon to open the oscilloscope application.
While the oscilloscope is warming up, run the self-test to ensure that the hardware is functioning
properly. To run the self-test:
c Pull down the Utilities menu and select Self Test.
d Select Scope Self Test from the Self Test list.
e Click on Start Self Test to start the self test procedure.
If any of the self-tests fail, ensure that the failure is diagnosed and repaired before calibrating
and testing performance.

Performance calibration.
After the warm up period, calibrate the oscilloscope.
a Connect the USB cable to the USB port located on the rear panel of the Digital Multimeter and
to a USB port on the oscilloscope (it is recommended that you use one of the side panel USB
ports on the oscilloscope instead of a front panel port).
b Connect the BNC to dual banana adapter to the Digital Multimeter’s input (the dual banana side
of the adapter is inserted into the DMM). Be sure the side labeled GND is connected to the
negative terminal of the dual banana adapter. Connect the BNC cable to the BNC side of this
Let the oscilloscope warm up before testing
The oscilloscope under test must be warmed up (with the oscilloscope application running) for at
least 30 minutes prior to the start of any performance test.
