Data Logger Sampling Modes

Model N6705 User's Guide
The DC 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 continuously samples the voltage or current
data at about 50 kHz. Both voltage and current can be continuously
sampled on Agilent Models N676xA and N678xA SMU. Power is
calculated from the instantaneous voltage and current values. Only
voltage or current can be continuously sampled on all other power
modules. An average value (and optionally, a minimum and
maximum value) is returned for each sample period. Continuous data
sampling is used for the following Power Module/Display Trace
selections:
Power Module
N676xA, N678xA SMU Voltage, Current, & Power (24 parameters maximum)
N673xB, N674xB
N675xA, N677xA
N6783A
Available capabilities for ALL outputs
● Sample period: 20.48 microseconds to 60 seconds
● Trigger source: all trigger sources available
● Trigger offset: 0 to 100%
● Values logged: average, minimum, maximum
(minimum/maximum values must be selected)

The fastest sample period that can be programmed for continuously-
sampled measurements is 20.48 microseconds. However, this speed is
only possible if one parameter is being measured. Note that you can
measure up to 24 parameters (average voltage+min+max X 4 outputs,
and average current+min+max X 4 outputs) with a corresponding
decrease in measurement sample rate. The following typical sample
periods are based on the number of parameters selected:
