5700A/5720A Series II Calibrator
Service Manual
3-32
Use Table 3-23 (5720A) or Table 3-24 (5700A) for the test records.
1. Place the 5790A on top of the Calibrator and connect the equipment as shown in
Figure 3-11.
Note
The point of measurement is at the end of the cable and adapter that
connects to the 5790A. Other cable lengths and adapters will yield
different results at high frequencies.
2. On the 5790A push UTIL MENUS button and then the MEAS CONTROL softkey.
Set the digital filter mode to FAST and the restart to MEDIUM. Push the DONE soft
key twice to return to the measurement display.
3. Set the 5790A to 2 mV at 1 kHz. Adjust the Calibrator using the output adjustment
knob for a reading of 2.0000 mV ±1 count on the 5790A. Record the Calibrator error
display reading in the 90 Day column in Table 3-23 (5720A) or 3-24 (5700A) as
appropriate for the verification interval.
4. Verify that the result is within the test limits.
5. Repeat the previous steps for the 2 mV output on all remaining frequencies on the
test record.
6. Proceed to the remaining output levels and frequencies list in Table 3-23 or 3-24 and
repeat steps 3 through 5 using the appropriate output level in each step, and the
adjustment tolerance in Table 3-8.
