Figure 3-4. Setup for MeasZ Calibration
Set the Calibrator Mainframe in Scope Cal mode at the prompt to connect a 40
resistor. Then follow these steps to calibrate MeasZ.
1. Connect the N to BNC cable to the SCOPE connector. Connect the other end of the
N to BNC cable to the BNC(f) connector attached to the 40
Figure 3-4 for the proper equipment connections.
2. Press the GO ON blue softkey.
3. Enter the actual 40
4. When prompted by the Calibrator Mainframe, disconnect the 40
connect the 60 resistance.
5. Press the GO ON blue softkey.
6. Enter the actual 60
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.
7. When prompted by the Calibrator Mainframe, disconnect the 60
connect the 0.6 M resistance to the end of the N to BNC cable.
8. Press the GO ON blue softkey.
9. Enter 0.6 M resistance
10. When prompted by the Calibrator Mainframe, disconnect the 0.6 M resistance and
connect the 1.5 M resistance to the end of the N to BNC cable
11. Press the GO ON blue softkey.
