Output Accuracy Test-Millivolt Ranges
Use the following procedure to perform the millivolt output accuracy test:
1. Connect the equipment as shown in Figure F-3.

Figure F-3. 100 mV Output Accuracy Equipment Configuration
2. Ensure the Equipment Set-Up procedure has been performed.
3. Set the 5200A output to 100 mV on the 100-mV range at 1 kHz.
Note
Internal sensing is automatic on the 5200A millivolt ranges.
4. Set the reference voltage of the 5790A to give a direct error read-out as follows:
a. Set the mode switch to OPR.
b. Adjust the 5200A output voltage if necessary to give the exact reading of
100.0000 mV (
±
10 counts) and push the SET REF soft key on the 5790A.
c. Push the soft key under the error display units to give PCT.
d. Reset the 5200A to 100 mV.
5. Perform the measurements at the frequencies desired. The readings should not be
greater than the values listed for the voltage/frequency selected in Table F-3.
