3000A SERIES CALIBRATION MANUAL

For multimeters such as the Agilent 3458A with limited maximum current, a selection
of current shunts are required. These current shunts should be suitable for both DC
and AC current up to 10kHz (5kHz for 2A Range, 1kHz for 30A range) Suggested
current shunt values are listed below, along with the current range they will be used
for :
0.1 Ohm – 2.02A to 30A AC/DC
1 Ohm – 202mA to 2A AC/DC
10 Ohm – 20.2mA to 200mA AC/DC
100 Ohm – 2.02mA to 20mA AC/DC
These shunts are also used for multimeters with insufficient current accuracy for low
current calibration.
Equipment required for Oscilloscope (SCPXXX)
option calibration
To calibrate the Oscilloscope output function of the 3000A series, the following
equipment is required
1. High Accuracy precision Multimeter
2. Frequency Counter / GPS Frequency Standard / Off-air Frequency Standard
3. 600MHz – 1GHz Oscilloscope (example Agilent Xfinity Series Oscilloscope)
