3 Operating the DC Power Analyzer
68 Model N6705A User’s Guide
Markers
Select the Markers button to configure the measurements that
appear on the bottom of the display in Marker view. Measurements
apply to the portion of the trace between the two markers.
Preset
Select the Preset button to return the Data Logger View to the
factory-shipped display settings. As shipped from the factory, the
vertical offset of each trace is 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 DC Power Analyzer provides two modes of data logging:
Continuously-sampled - the default, and Standard (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
Continuously-sampled continuously samples the voltage or current
data at about 50 kHz. Both voltage and current can be continuously
sampled on Agilent N676xA Power Modules. Power is calculated from
the instantaneous voltage and current values. Only voltage or current
can be continuously sampled on all other power modules. Continuous
data sampling is used for the following Module/Trace selections:
Power Module Display Trace selection Available capabilities set for ALL outputs
N676xA Voltage, Current, and Power ● Sample period = 1 ms to 60 s
N673xB, N674xB Voltage or Current ● Trigger source = all trigger sources available
N675xA, N677xA Voltage or Current ● Trigger offset = 0 to 100%
● Values logged = average, minimum, maximum
(minimum/maximum values must be selected)
