Active Filter
J2190A
-
The J2190A active filter presents a high impedance (approximately 150kOhms) minimizing the loading of the circuit being tested. The output impedance is 50 Ohms allowing low noise coaxial connections to all typical test equipment. The 0.1Hz-10Hz noise band is common for opamp measurements, voltage regulators and voltage references. Many application notes offer schematics of such a filter for test purposes. An engineer’s time is much too valuable to be spent building test equipment. We have created a 4th order high pass and 4th order low pass filter with an optimally flat response and 0dB gain. Additional filters can be cascaded for even sharper cutoff.

Colorimeters
-
A colorimeter is a valuable color-measuring tool used by manufacturers, printers, painters, designers and quality control professionals. Colorimeters ensure accurate, consistent color, eliminating issues related to color subjectivity. Depending on the model, PCE Instruments' colorimeter products can measure colors in different color spaces such as CIE LAB, XYZ, LCh, RGB and LUV (for liquids and solids / that is why you can choose the media via filter selection). The most popular colorimeter models in our range of color-reading products are the PCE-CSM series colorimeters. Aside from being easy to use and economical, the PCE-CSM series colorimeters offer high degrees of accuracy.

Test Data Organization
-
Filters enable you to organize your data in a dynamic rather than a static way. Using filters, you can organize your issues, tests, testSets, and requirements, based on their fields, and have the information, displayed in multiple ways. For example, you can create 2 filters in the Test library module - one that displays the tests that are related to the DB server and the other filter displaying tests whose priority is ‘Show Stopper’. A test that has its component field set on ‘DB server’ and its Priority set on ‘Show stopper’ will appear in both trees accordingly.

PWM TO VOLTAGE SIGNAL CONVERTER
RCPWM2V
-
The RCPWM2V is a device that converts a standard hobby RC signal (1-2ms pulse) into a proportional analog voltage (0-5V). In many electronics applications the main processor is constantly busy and does not have the ability to address the time-sensitive PWM signal from an RC receiver immediately. This results in signal distortion or a sluggish response due to the extra filtering required. The RCPWM2V provides a simple solution by converting the signal into an analog signal. The main processor can then read the signal whenever it has time.
