Low-cost, high-quality switching for
automated test
If you don’t need the built-in measurement capability of the
34970A/34972A, save money by ordering it without the DMM�
What you end up with is the lowest cost switch unit on the
market� It’s an ideal solution for routing test signals to and from
your DUT and assorted instruments, including external DMMs,
scopes, counters, and power supplies� Plus, you can add the
DMM later if your needs change�
The functionality you need
We put a lot of thought into defining and designing the modules
for the 34970A/34972A in order to cover a broad spectrum of
switching and signal routing requirements with fewer modules�
The result? Simplified ordering and easier configuration� And
while we were at it, we improved performance and density� The
34970A/34972A modules can switch from microvolts to 300
volts, dc to 2 GHz, and with densities as high as 120 single-ended
channels or 96 matrix crosspoints per frame� Plus, simple control
capabilities like analog outputs, open collector digital outputs,
and isolated Form-C relays for controlling higher-powered
devices are available�
Low-cost switching system for automated testing
Easy scanning
The 34970A/34972A can easily scan with external instruments�
It builds a scan list that includes all enabled low frequency
multiplexer inputs� Scans are controlled with the external channel
advance input, or with the front panel Step key�
Connect to the company network
With the 34972A’s LAN interface, the instrument is easily
connected to the company network to collect measurement data
to a central database, remotely access the instrument’s set up, or
monitor measurement data from anywhere on the network�
