Back Plane Tester
-
This machine is used to test back planes used in telecommunications central stations. An operator loads a completed point to point wired back plane onto a retractable shelf on the front of the tester. Table continues and the disk falls through a hole into the bin. The shelf is pushed back into the machine where it is held in place by pneumatic operated clamps. Then a series of pneumatic cylinders sequentially insert a test card into each location in the back plane. A remote instrument performs a complete point to point continuity, short and hi pot test on all connections in the back plane.

PXI/PXIe Analog Output/Current Loop Simulator Module - 12 Channel
43-765-002
Analog Output Module
The 41/43-765-002 is a 12-channel Analog Output Module designed to meet the requirements of industrial control applications utilising current loops 4 – 20mA. It consists of up to four 16-bit, digital-to-analogue converters (DAC), capable of creating four current outputs each. Output current within 0mA - 4mA and 20mA - 24mA, give the ability to simulate error or extra signalling conditions. The ±24mA mode gives the ability to simulate either sourcing or sinking sensor.

Dual Loop Master Controller
-
The Xcite System Master Controller provides all dual loop functions needed for accurate closed loop control and display of the static and dynamic test variables, while producing the highest electro-hydraulic frequency response. At the heart of each Xcite System is the Master Controller, a compact electronic control package which provides all of the controls and displays necessary to operate a controlled force or torque exciter system. The Xcite Master Controller is unique in that it provides electro-hydraulic excitation over a broad frequency range, unprecedented by any previous electro-hydraulic excitation system. It achieves its great frequency range through the use of sophisticated circuitry, high voltage inputs to the servovalve and compression control of the dynamic feedback variable in addition to the conventional servo control of the static loop. Static parameters such as force or displacement may be matched with dynamic control variables such as force, displacement, velocity, acceleration or strain for maximum test flexibility.

4-20mA Current Loop D/A Converters
-
ADI integrated solutions combine both the D/A converter and driver in one chip to provide the required output directly from the digital domain. Analog Devices’ portfolio of leading industrial D/A converters and drivers provides a range of programmable output ranges from standard 4 mA to 20 mA for current loop communication to ±10 V for actuator control. ADI industrial converters offer considerable control functionality and advanced on-chip diagnostics to maximize system uptime, as well as eliminate the need for costly calibration routines needed by some traditional discrete architectures.

Active Loop Antenna
AL-130R
-
Also known as Magnetic Loop Antenna, the AL-130R is compliant with CISPR 16-1-4. It is ideal for emissions measurements as required by various EMC standards such as FCC 18, CISPR 11, CISPR 13, CISPR 14, CISPR 32 and many more. The built-in, low-noise preamplifier, increases overall measurement sensitivity as well as the overall signal to noise ratio. As per ANSI C63.4-2014, the use of active loop antenna for compliance testing is permitted in a non-sheilded environment ONLY if the saturation indicator is continuously monitored during the course of testing. Com-Power’s Remote Antenna Interface (RAI-100) comes in very handy for this application. It is a compact controller which can be used to enable/ disable RF measurement circuit and monitor saturation and battery low conditions remotely via a fiber optic cable up to 30 mtrs in length.
