C-2
Data Flow
Introduction
Data
fl
ow for remote operation is summarized by the block diagram shown in Figure C-1.
Refer to this block diagram for the following discussion.
The SENSE block represents the basic measured readings of voltage, current and resistance.
If Filter is enabled, the readings will be
fi
ltered. The SENSE block also measures time for the
timestamp.
When the INITiate command is sent, the programmed number of source-measure operations
are performed and the respective data is temporarily stored in the Sample Buffer. For example,
if 20 source-measure operations were performed, then 20 sets of data will be stored in the Sam-
ple Buffer. Data from this buffer is then routed to other enabled data
fl
ow blocks.
