BenchLink Data Logger Pro Software
for Agilent 34970A
Data Sheet
Advanced data logging
and decision making with
no programming
Key features
• Quick test setup and execution
• Create multiple scan lists
• Use advanced math functions
• Collect, monitor and manage data
• Present data on a single or
multiple graphs
• Export data to other applications
for presentation and analysis
The Agilent BenchLink Data Logger Pro
software provides a convenient way to
collect and analyze your data. This software is a Windows®-based application that
uses a familiar spreadsheet environment to
define measurement data to be collected.
The tab-based format makes it easy to set
up multiple scanlists and initiate scans
Scan list A
based on predefined limits. Simply identify
the measurements you want to acquire,
define limits and actions to be performed,
and then initiate the process. Your data
is then collected, acted on real-time and
displayed in table and graphical formats.
With the BenchLink Data Logger Pro
software you get advanced data logging
and decision making capabilities without
spending hours programming.

BenchLink Data Logger 3
Your 34970A Data Acquistion 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
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.
• 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 programming 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
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

Data Logger 3 Data Logger Pro
The state diagram feature graphically
shows the limits and the order of execution for scan lists, scripts and other
notifications. See Figure 2.
Computed channels
Statistical calculations can be added
to analyze unique data points. Create
computed channels for mathematical
relationships with +, –. *, /, dB, dBm,
dBV, x2, SRT, full, ½ or 1/4 bridge strain.
BenchLink Data Logger Pro adds a calculator function for additional math functions
such as Sin, Cos, Tan and Log. Formulas
can also be used for more complex equations including polynomial equations.
Graphing and exporting data
The raw data is saved in Comma separated
variable format (.CSV) and can be easily
imported into standard Microsoft® applications such as Microsoft Word and Excel®
for further analysis and documentation.
Whether monitoring incoming data or
reviewing historical data, you can use one
of the many analog or digital options to
display your data.
Data management is vital for data logging
applications. The BenchLink data logger
Use strip charts with markers and alarm
indication, or histograms with statistics.
The data can be displayed with the auto
scale or centered on a common reference
The Windows user interface is also localized into multiple languages and includes
context sensitive help.

Graph your data, save it to disk, or export
it to other applications for further analysis.
Use the quick graph tab to monitor data
real time. You can specify multiple channels per graph, or send collected data to
multiple graphs.
software features a data manager that
allows you to easily manage all configurations and dataset files. Use this feature to
copy instrument settings, find related data
logs, rename files, edit comments, export
data logs to .CSV format or just delete
unwanted data.
