9. 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.
10. Connect the equipment as shown in Figure F-5.
11. Set the 5200A output to 1 mV on the 1-mV range at 1 kHz.
12. 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 1.0000
mV (±2 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 1 mV.
13. Perform the measurements at the frequencies desired. The readings should not be
greater than the value listed for the voltage/frequency selected in Table F-3.
Figure F-5. 1 mV Output Accuracy Equipment Configuration
Voltage Error Control Test
Use the following procedure to check the voltage error control:
1. Ensure that the Equipment Set-Up procedure has been performed.
2. Connect the equipment as shown in Figure F-2.
3. Set the 5200A for an output of 10 V on the 10 V-range and at 1 kHz on the 1-kHz
range.
4. Set the MODE switch to OPER.
5. Push the SET REF soft key on the 5790A.
6. Set the VERNIER dial to 0.00 and the VOLTAGE ERROR-% switch to X1. The
5790A error display should read 0 ±.01 %.
7. Set the VOLTAGE ERROR-% switch to X1. The 5790A error display should read 0
± 0.001 %.
