Calibrating and Entering Power Analyzer Voltage Calibration Values
Action Display
4. Connect an Agilent 3458A DVM (in synchronous ac volts mode) to the ac source
output terminals. Short the Power Analyzer voltage terminals (V SENSE) to
ensure no dc offset error.
5.
Press Shift Calibration, scroll to CAL VOLT EXT, and press Enter.
CAL:VOLT:EXT
6. Leave the ac source on and remove the short from the Power Analyzer voltage
terminals.
7. Connect the Power Analyzer voltage sense terminals to the Main Output
terminals of the ac source
(see figure 3-1A).
8.
Press Shift Calibration, scroll to CAL LEV P1 and press Enter.
The ac source will output 300 Vac 60 Hz sine wave.

Calibrating and Entering Power Analyzer Current Calibration Values
Action Display
11. Short the Power Analyzer current sense terminals (I SENSE) to ensure no dc
offset error.
12.
Press Shift Calibration, scroll to CAL CURR EXT and press Enter.
CAL:CURR:EXT
13. Leave the ac source on and remove the short from the Power Analyzer current
terminals.
14 Connect the Power Analyzer current terminals to the output of the function
generator (see figure 3-1B). Set the function generator output to 50 mV, 60 Hz.
15. Connect the Power Analyzer current terminals to the Agilent 3458A input
terminals. Note that the Agilent 3458A must be in synchronous ac volts mode and
a 1.0 uF capacitor must be installed across the Agilent 3458A input terminals.
