Set Up Device Analysis Input Channels

This procedure selects the voltage and current source channels and makes any necessary offset or
deskew adjustments to ensure measurement accuracy.

If you have just completed the preliminary deskew procedure, begin at Step 6.

1. From the menu bar, choose Analysis > Power Analysis to open the Power Analysis dialog.

2. Check Enable.

3. Select the Voltage Source channel where the voltage probe is attached.

4. Select the Current Source channel where the current probe is attached.

NOTE: The current input channel is automatically assigned Ampere units.

5. Touch the Input Settings tab and enter the current probe Deskew value obtained during the pre-

liminary deskew procedure.

6. Choose the current ProbeType. If you’re using a current device other than a probe (e.g., shunt res-

istor), also make these entries:

If an amplifier, also enter the Amps/div.

If a shunt resistor, also enter Shunt Resistor Ohms.

7. If necessary, touch Select Source and make any final adjustments on the voltage or current Channel

setup dialogs.

NOTE: If you change the probe, bandwidth or filter settings at this point, repeat the

8. Choose Display > Auto Grid and set up peak-to-peak waveforms to utilize the full Analog-Digital Con-

verter (ADC). The waveform should cover the full height of the grid.

9. When you have obtained a stable display, go on to
