Data Logger Presets
Select the Preset button to return the Data Logger View to the power-on display settings. The vertical
offset of each trace will be set to a different value. This is to prevent the traces from overlapping. The
offset is referenced to the horizontal center line of the grid.
Data Logger Sampling Modes
The power analyzer provides two modes of data logging: Continuously-sampled mode (the default),
and Standard (or interleaved) mode. The mode is automatically selected based on the installed power
module types and the selected measurements, and applies to all outputs. A text message in the
Display Trace area of the Data Logger Properties window indicates which mode is in effect.
Continuously-sampled mode
Continuously-sampled mode continuously samples the voltage or current data at 200 kHz for Models
N678xA SMU, and at 50 kHz for all other power modules. Both voltage and current can be sampled
continuously on Models N676xA and N678xA SMU. Power is calculated from the instantaneous
voltage and current values. Either voltage or current can be sampled continuously on all other power
modules. Only the averaged value (and optionally, a minimum and maximum value) is returned for
each sample period.
Continuous data sampling is available for the following power modules with the indicated display
trace selections:
Power Module
N676xA, N678xA
N673xB, N674xB
N675xA, N677xA
N6783A-BAT/MFG
Available capabilities for ALL outputs
• Sample period: 20.48 microseconds to 60 seconds
•Trigger source: all trigger sources available
