Polarity Tester
PT-1
-
International Electro-Magnetics, Inc.
The PT-1 provides a simple and easy way to determine the relative polarity of coil windings. It allows for an in-process test that takes a minimum of time to perform. By placing a coil on the platform and making connection to the start and end of a winding, a test signal is induced in the winding. The induced signal is low level and completely safe for the operator. By comparing the test signal phase of the coil under the test output, the relative polarity is indicated by the Red/Green LED. The tester operates by inducing a signal voltage in the coil under test by means of a magnetic flux field. The field is generated by a coil located in the probe base. The coil configuration is designed to provide optimum field distribution. We have also applied this basic circuit to a 5-channel scanning unit.

Automatic Bias Controller
MATRIQ-IQABC
Controller
Optimizing DC bias points of an IQ modulator is no trivial task. There are six different Mach-Zehnder structures inside one dual polarization IQ modulator, all simultaneously influencing the properties of a single optical signal. Trying to optimize bias points using just the intensity measurement of the optical signal is time consuming, inaccurate and it requires a lot of knowledge and experience.

Radiant Technologies, Inc. specializes in the measurement of electrical and piezoelectric properties of non-linear materials. The Piezoelectric Task captures a sample's displacement as a function of voltage profile along with the sample's polarization response. An external displacement measurement instrument must be attached to a Radiant Precision Test System to make this measurement. All of the Radiant testers are equipped with a high-impedance voltage input to capture the output of a displacement sensor. Every Vision measurement task will collect data from that sensor input simultaneously with the measurement being executed. Radiant's test systems work easily with displacement sensors which include:
