BenchLink Data Logger 3
Your 34970A/34972A Data Acquis-
tion Unit comes standard with the
BenchLink Data Logger 3 Software.
This software gives you all the basic
data logger capabilities including:
– Easy connection to the PC
– Set up measurements and scan
lists
– Computed channels and alarms
– Collection, graphing and export of
your data
The BenchLink Data Logger Pro
software adds advanced data logging
and decision making with no program-
ming required. See Table 1 for a list of
standard features in both products.
Multiple scan lists
With BenchLink Data Logger Pro you
can identify multiple scan lists to be
executed based on different limits
specified in your configuration.
Setting limits and events
Set limits to identity when to start
other tasks. For out of limit conditions,
you can specify for different events to
be completed.
Scripts can be used to close switches
or send DIO within the data acquisition
unit, or SCPI commands can be sent
to other instruments connected to
the PC. For example, when an oven
reaches the desired temperature limit,
you can start a script. The script can
send a SCPI command to the power
supply to change the input power to
your device under test and switch to a
faster scan rate to collect the desired
measurements.
For out of limit conditions other
notifications such as an audio beep,
log events or run an external program
can also be performed. See Figure 1.
