Cable Fault Meter
-
A cable fault meter can locate open power cables, either live or dead (without current), with voltages up to 300 V. A cable fault meter can locate cables, circuits, short circuits and ground wires. To perform these functions, it is not always necessary to disconnect electrically sensitive devices or to disconnect the power from the cable which is being tested. Many cable fault meter devices can also locate ferrous and non-ferrous metals, wood and plastic with high degrees of accuracy.

Circularly Polarized Luminescence (CPL) Spectrophotometer
CPL-300
-
The circularly polarized luminescence spectrophotometer supplements the information obtained from other chiroptical techniques such as electronic or vibrational circular dichroism. Circular dichroism (CD) spectroscopy is widely used in the study of optically active substances. CD spectroscopy provides information about the structure of optically active substances in the electronic ground state, however, CPL spectroscopy provides information about excited states. The two techniques are therefore complementary.

Modular Relay Board
-
Alliance Support Partners, Inc.
An increasing number of electronics products are being assembled in panels of 8 or more to minimize production cost. These products are typically tested with in-circuit tests (ICT) followed by power-on functional tests. Normally, ICT requires isolation of power and ground while measurements are being performed. Functional tests, including in-system programming (ISP), require board power to be applied. The Modular Relay Board (MRB) is designed to switch power onto each individual board and to disconnect sensitive signals during functional test.

Measuring Small Antennas
-
If you have a small PCB with a small antenna you can't use a thick cable and a large connector. Not only is this impractical (how to connect the connector?) but the metal bulk will also affect the antenna and grounding properties of your PCB. The measurement will be useless. MegiQ promotes the use of the small and popular UFL connector and its associated cables. The UFL socket fits on almost any PCB and it can be improvised on a board without a UFL footprint.

Voltage Variation Simulator
KES7400A
-
The KES7400A Series comes in a single cabinet that consists of a Signal Generator module (including an arbitrary pulse generator), which combines our power supply technology and EMC technology, and a high-speed bipolar power supply module. Many automotive electronic devices have long wire harnesses and inductive load characteristics, as do motors, or capacitive load characteristics with a large-capacity capacitor connected between the input and ground. In the case of these devices, general DC power supplies exceed the linear operation range, potentially making it impossible to obtain the desired waveform output.
