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 6000 Series Oscilloscopes
Service Guide using traceable sources.
To perform User Cal
1 Set the rear-panel CALIBRATION switch to UNPROTECTED.
2 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 50Ω 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.
