To set the calibration factors after replacing the acquisition board
The following procedure must be performed after replacing the acquisition board. This procedure needs
to be performed only once after the acquisition board is replaced.
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.

a Exit the oscilloscope application.
b From a command prompt, run the oscilloscope software using the following syntax:
c:\scope\bin\agscope.exe -service
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.
2 Performance calibration.
After the warm up period, calibrate the oscilloscope.
a Connect the RS-232 cable to the Digital Multimeter RS-232 port and to the RS-232 port on the
oscilloscope.
b Set Digital Multimeter as follows:
