SOP FOR Impedance Annalysis:

1. Switch on the power supply.

2. Press line button at the bottom left of the front panel. This will display a screen saying power on in progress.

3. Press [DISPLAY] and choose SPLIT on OFF.

4. Press [Meas] then choose CP – G/Z-θ.

5. Press [Sweep] then PARAMETER then DC BIAS/ FREQUENCY.

6. Press [START] to choose starting voltage/frequency & then press [STOP] to choose stopping voltage/ frequency.

7. Press [Cal] then FIXTURE COMPENSATION then OPEN.

8. Now connect DUT.

9. For Cp-G Press [source] then frequency to choose sweep frequency. Press [source] then BIAS on OFF to turn DC bias on.

10. Press [trigger] then SINGLE.

11. To save the data in a floppy disk, Press [save]then DATA then ASCII the enter the file name.

12. Keep taking readings for different frequencies.

13. When finish press [source] then BIAS MENU then BIAS ON off to turn DC bias off.

14. Press [Preset]then [Entry off]

15. Press bottom left line button to shut down the machine.

16. Switch off the power supply.

17. Remove DUT from the base plate.

DONT’s:

1). Do not press [reset] or [entry off] button before switching off DC bias.

2). Do not disconnect the DUT without switching off DC bias.

3). Do not press/push the probe pin too hard as they may rupture the device.

When there is power failure:

· Follow steps 14 to 17 of operation steps of CV profiling.
