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

• 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

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 notifica-

tions such as an audio beep, log events

or run an external program can also be

performed. See Figure 1.
