Power Device Analysis Setup (Deskew Value Check)
After the voltage and current channels are assigned, the value of time delay correction required
between the two can be set by touching inside the
Deskew
field in the "Current" dialog.
The deskew value can be changed in this dialog by turning the front panel Adjust knob or by
using the pop-up keypad.
Note:
The deskew value should not be changed in this dialog unless the correct value is known.
Voltage and current signals that occur in the circuit under test may not be properly phase related,
and using them for deskew purposes can cause major errors to occur in the measurements.
Time-coincident voltage and current signals such as those provided by the DCS015 Deskew
Calibration Source should be used.
Power Device Analysis Measurements
Note:
The previous sections should be completed before you make these measurements.
After the channel-to-channel propagation delay is matched and the previous measurement setup
is completed, measurements on the device under test can proceed.
1.
From the menu bar, select
Analysis
, then
PowerMeasure
from the drop-down menu; the
"PowerMeasure" dialog opens.
2.
Touch the
Device
button. The choices of measurement are as follows:
•
Instantaneous Power
measures the instantaneous power loss in the power FET.
•
Safe Operating Area
measures the power FETs safe operating area.
•
Dynamic On-Resistance
measures the power FETs saturation voltage and its
dynamic on-resistance.
•
DV/DT
measures the derivative of the voltage.
3.
Touch the
Voltage
tab, then touch inside the
Fine Adjust DC Level
field. This field
enables you to correct small DC offset errors without having to remove the probe from
the circuit. Enter a value, using the pop-up keypad, or use the fine adjust front panel
knob.
4.
Touch the
Current
tab; perform the same DC offset correction, as necessary.
