And the DAQ970A measures and converts 12 different input 
signals:

 

– Temperature with thermocouples, RTDs, and thermistors

 

– dc and ac volts

 

– 2- and 4-wire resistance

 

– Frequency and period

 

– Capacitance and diode

 

– Strain

What’s more, each channel is independently configurable. This 
means you can configure channel 1—for dcV, channel 2 for a 
K-type thermocouple, and channels 3 and 13 for a 4-wire RTD 
measurement—all on the same module, all in a single scan. For 
custom linear conversions, use the Mx+B scaling function on any 
channel. You can even display a custom engineering label like 
RPM or PSI to identify your measurement units.

Versatile alarms

Alarms are available on a per-channel basis as well. Enter a high 
limit, a low limit, or both. The DAQ970A compares each reading 
to its limits and flags any out-of-range measurements. You can 
assign one of four TTL alarm outputs to any input channel to 
trigger external alarm lights, sirens, or send a TTL pulse to your 
control system, all without a PC connected.

Scanning made simple

The DAQ970A automatically builds a scan list that includes all 
configured inputs (even digital inputs from the Keysight multi-
function module) in ascending order by channel number. You can 
pace scans by setting the DAQ970A internal timer for automatic 
scanning at a specific interval, by manually pressing a front-panel 
button, or by sending a software command or external TTL 
trigger pulse.

Monitor any input

A special display mode monitors a selected input channel, 
continuously updating the display with new readings—even 
during a scan. Or, when using the DAQ970A with built-in LAN, the 
channels can be monitored over the network using the graphical 
Web interface. It’s great for keeping an eye on a key input, or for 
troubleshooting your system before a test.

Non-volatile memory and USB flash drive adds 
convenience, portability

All readings are automatically time-stamped and stored in a 
nonvolatile 100 k reading memory—enough memory to hold 
more than a week’s worth of data (20 channels scanned every 
five minutes). The nonvolatile memory holds your data even after 
power is removed, so you can use the DAQ970A to collect data at 
a remote location for later uploading to a PC. Or if you need even 
more memory, the DAQ970A USB port can be used to log data 
directly to a USB flash drive or to copy the data from the reading 
memory without being connected to a computer.

logging applications

A powerful, flexible data acquisition system for 
automated test

The DAQ970A gives you the resolution, accuracy, repeatability, 
and speed you’ve come to expect from a Keysight data acquisition 
system. It provides the measurement muscle you need, along with 
signal routing and control capability, in a flexible, modular format 
that can grow and change to match your varied applications.

Powerful measurements

The internal 6½ digit DMM brings the power and performance 
of a world-class stand-alone DMM to the DAQ970A, but at a 
fraction of the cost and in a fraction of the space. It’s as accurate 
as the best bench DMM available: 0.004% basic 1-year dcV 
accuracy, 0.06% basic 1-year acV accuracy, and 0.01% basic 
1-year resistance accuracy. Our patented A-D technology offers 
incredible linearity (2 ppm of r1 ppm of range) along 
with 22 bits of real resolution. And since it is an integrating A/D, 
it provides excellent noise rejection as well—a nice change from 
noisy and sampling A/Ds. No more averaging lots of samples just 
to see the real data you wanted. And if you need high scan rates, 
the DAQ970A is capable of delivering fully converted measure-
ments at speeds up to 450 ch/s.

The input section of the DMM is optically isolated and shielded 
from the DAQ970A earth-referenced circuitry and computer 
interface, offering up to 300 V of input isolation. This is important 
for reducing ground loop and common mode voltage errors 
associated with long wiring runs and floating measurement 
sources.
