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.

RF Filters
-
RF Filters block unwanted frequencies when testing electronic devices for emissions during EMC testing. They attenuate unwanted frequencies and allow the desired signals through. The RF filters isolate the device under test from external RF noise, this increases the reliability and accuracy of the EMC testing by preventing out-of-band noise and harmonics.
