Atec Agilent-34980A - Manual (Page 3)

Make system connections easily
and quickly with simple, reliable
connection options:
• Built-in Ethernet, USB 2.0, and
GPIB connectivity
• Standard IVI and LabVIEW software
drivers
• Low-cost, standard 50- or 78-pin
Dsub connectors and cables
• Detachable terminal blocks with
strain relief
• Mass interconnect solutions
In addition, the 34980A comes with
Agilent E2094N IO Libraries Suite
14.0. Quickly establish an error-free
connection between your PC and
instruments—regardless of vendor.
The I/O Libraries provide robust
instrument control and work with the
software development environment
you choose.
Easier signal routing with four
2-wire internal analog buses. You can
route your measurements directly to
the internal DMM, or you can connect
to external instruments through the
analog bus connector on the rear of
the mainframe. And since you have
four 2-wire buses, you can dedicate
one bus for use with the internal
DMM and use the other three buses
for module extensions or additional
signal routing between modules,
reducing your wiring needs.
You can define switch sequences to
control complex signal routing and
the order of switch closures. Assign
a sequence, give it a name and then
execute it with the name you created.
You also can define lists to identify
channels that should never be
connected together.
External trigger capabilities make it
easy for you to time and synchronize
measurements and other events. This
can help you determine when to begin
or end an acquisition.
Measurements you can trust
Get proven performance from Agilent
instruments, with the resolution,
repeatability, speed, and accuracy
you’ve come to expect.
The 34980A offers built-in signal
conditioning and modular flexibility.
When you use it with the internal
DMM, you can configure each channel
independently for the measurements
you choose. It includes a variety of
features that give you confidence in
your measurements:
• 6 1 ⁄
2
digits of resolution with .004%
of accuracy with DC voltage
measurements
• Alarms per channel—high limit,
low limit, or both
• Math functions—use Mx+B for
custom linear conversions and
converting raw inputs
• Built-in thermocouple reference
for temperature measurements
(34921T)
• Time-stamped readings
The integrated DMM is mounted
inside the mainframe and does not
consume any of the eight user-
available slots. You can access the
DMM through any switch module that
connects to the analog bus, or directly
from the analog bus connector on the
rear of the mainframe. The internal
DMM gives you the flexibility to
measure 11 types of inputs:
• Temperature with thermocouples,
RTDs, or thermistors (with 34921A)
• DC and AC voltage
• 2- and 4-wire resistance
• Frequency and period
• DC and AC current
You can control the DMM directly, or
configure it to work in conjunction
with the switches. Each switch channel
can be configured independently for
measurement functions, scale factors
and alarm limits. Advanced measure-
ment features such as offset compen-
sation, variable integration time, and
delay are also selectable on a per-
channel basis.
The DMM inputs are shielded and
optically isolated from the 34980A’s
earth-referenced circuitry and
computer interface, and as a result,
you get up to 300 V of input isolation.
This is important for reducing
ground-loops and common-mode
voltage errors associated with long
wiring runs and floating sources.
Simple DMM calibration is
accomplished with just the analog
bus connection on the rear panel of
the mainframe. You don't need to
remove the mainframe from the rack
or dedicate a channel for calibration.
