Performing User Cal will invalidate your Certificate of Calibration. If NIST
(National Institute of Standards and Technology) traceability is required,
perform the "Performance Verification" procedure in the
Agilent
InfiniiVision 4000 X- Series Oscilloscopes Service Guide using traceable
sources.
To perform user calibration:
1
Disconnect all inputs from the front and rear panels, including the
digital channels cable on an MSO, and allow the oscilloscope to warm
up before performing this procedure.
2
Press the rear- panel CAL button to disable calibration protection.
3
Connect short (12 inch maximum) equal length cables to each analog
channel's BNC connector on the front of the oscilloscope. You will need
two equal- length cables for a 2- channel oscilloscope or four
equal- length cables for a 4- channel oscilloscope.
Use 50W RG58AU or equivalent BNC cables when performing User Cal.
For a 2- channel oscilloscope, connect a BNC tee to the equal length
cables. Then connect a BNC(f)- to- BNC(f) (also called a barrel
connector) to the tee as shown below.
