Figure 6-5. MeasZ Function Calibration Setup
Set the Calibrator Mainframe in Scope Cal mode at the prompt to connect a 50
Then follow these steps to calibrate MeasZ.
1. Connect the BNC cable to the SCOPE connector. Connect the other end of the BNC
cable to the BNC(f) connector attached to the 50
2. Press the GO ON blue softkey.
3. Enter the actual 50
The Calibrator Mainframe will warn when the entered value is out of
bounds. If this warning occurs recheck the setup and carefully re-enter the
actual resistance insuring proper multiplier (i.e., m, u, n, p). If the warning
still occurs, repair may be necessary.
4. When prompted by the Calibrator Mainframe, disconnect the 50
connect the 1M resistance to the end of the BNC cable.
5. Press the GO ON blue softkey.
6. Enter the actual 1M resistance.
7. When prompted for the first reference capacitor by the Calibrator Mainframe,
disconnect the 1M resistance and leave nothing attached to the end of the BNC
cable.
8. Press the GO ON blue softkey.
9. Enter 0.
10. When prompted for the second reference capacitor by the Calibrator Mainframe,
connect the 50 pF capacitance to the end of the BNC cable.
11. Press the GO ON blue softkey.
12. Enter the actual 50 pF capacitance.
