Project plan for Pulse-IV Complete
Running AutocalScope
AutocalScope should be run before any pulse calibration is performed. For best
Pulse IV results, the AutocalScope should also be run before the first experiments
of the day.
To run AutocalScope:
1. The 4200-SCS should be turned on at least 30 minutes before performing any calibration or
measurements.
2. Double-click AutocalScope in the project navigator (Figure 3-36).
3. Click the green Run button.
4. Follow the instructions given in the pop-up dialog box and disconnect all connections to the
scope card.
5. The scope performs an autocal, which takes about one minute.
6. The test is complete when the Run button turns green. In the Sheet tab,
autoCalStatus=0 means that there were no errors.
7. Reconnect the cables to the scope card. Use care when installing the cable to the scope
card trigger SMB connector.
Running PulseIVCal
Verify proper setup by running a scope-shot. For on-wafer testing, have a through,
or short, structure available, or ensure that sharing a pad for both the gate and
drain probes provides a good connection. There are two steps to the calibration,
open, and through/short.
To run PulseIVCal:
1. If not already performed, run AutocalScope as explained above.
2. Double-click PulseIVCal in the project navigator (see Figure 3-36).
3. Click the green Run button to start the PulseIVCal.
