Performance Verification Checks
Starting on page 4-5 of the 5200A manual, the following procedures replace the Output
Accuracy Test - Voltage Ranges, Output Accuracy Test - Millivolt Ranges and Voltage
Error Control Test.
Output Accuracy Test - Voltage Ranges
Use the following procedure to perform the output accuracy test.
1.
Connect the equipment as shown in Figure F-2.

2. Ensure the Equipment Set-Up procedure has been performed.
3. Select the desired output voltage and frequency from the 5200A. Suggested
representative voltage and frequency combinations along with accuracy tolerances are
listed in Table F-2.
4. Set the reference voltage of the 5790A to give a direct error read-out as follows:
a. Select the desired voltage from the 5200A at 1 kHz.
b. Set the MODE switch to OPER.
c. Adjust the 5200A voltage if necessary to give the exact desired reading on the
5790A display (
±
10 counts) and push the SET REF soft key on the 5790A.
d. Push the soft key under the error display units to give PCT.
e. Reset the 5200A to the desired output voltage.
5. Perform the measurements at frequencies desired.
6. Repeat steps 3 through 5 for other desired voltage and frequency combinations.
