High Frequency Zero Calibration
Use the following procedure to perform the high frequency zero calibration test:
1. Set the 5200A output to 1 V on the 10 V range and 1 MHz on the 1-MHz range.
2. Adjust HIGH FREQ ZERO (R89, AC/DC Converter PCB) if necessary to give a
5790A reading of 1.000000
±
0.000100 V.
High Frequency Gain Calibration
Use the following procedure to perform the high frequency gain calibration test:
1. Set the 5200A output to 1 V on the 1 V range and 1 MHz on the 1-MHz range.
2. Adjust HIGH FREQ GAIN (R91, AC-DC Converter PCB) if necessary to give a
5790A reading of 1.0000000
±
0.000100 V.
3. Repeat the High Frequency Zero Calibration and High Frequency Gain Calibration
until both are within tolerance.
High Frequency 100v Range Calibration
Use the following procedure to perform the high frequency 100 V range calibration test:
1. Set the 5200A output to 10 V on the 100 V range and 1 MHz on the 1-MHz range.
2. Adjust 100V-HIGH FREQ (C3, Attenuator PCB) if necessary to give a 5790A
reading of 9.96700 V
±
0.00500 V.
Note
The output at 1 MHz is purposely adjusted 0.33 % low in order to optimize
accuracy at lower frequencies.
