How your 3499A/B/C Test System

Benefits From Upgrading to the New

34980A Switch/Measure/Control System

Application Note

This application note will describe

differences and advantages of the

new 34980A as compared to the

3499A/B/C. The 34980A

Switch/Measure System masters

switching, measurement, and

control features by offering a

superior selection of switch

topologies and system control

features. A state-of-the-art DMM

has been integrated into the

34980A mainframe providing a

wide variety of measure capability.

The 34980A mainframe also

includes standard PC connections

and instrument control options for

your ease of use.

Discover the detailed advantages of

upgrading your test system using

the 34980A in this document.

Measurements

One of the advantages of the new

34980A is its ability to make

highly accurate test system

measurements. The integration of

a high-speed DMM into the

mainframe enhances the 34980A

switch and control system by

providing voltage, current,

temperature, frequency, and

resistance measurements without

using any of the mainframe’s

available eight slots. The DMM

conveniently generates

measurement results in selectable

engineering units. Eleven

different types of measurements

can be made and are listed on the

page 2. The 34980A time-stamped

measurement data can be stored

or displayed and analyzed as the

measurements are acquired. The

34980A also has configurable

High/Low limits on each channel

that activate an alarm if the input

signals are out of the set range.

The 34980A’s integrated DMM

saves you time and money by

reducing the number of individual

instruments required, and

additional cabling for

measurements and triggering. In

comparison, the 3499A/B/C

switch requires an external DMM

or other measurement instrument

as well as additional wiring to

provide the same functionality.

Add functionality, streamline your test

programs, and reduce the physical test

system size by upgrading from your

3499A/B/C to the new 34980A

Multifunction Switch/Measure Unit.
