Filtered Analog Input Expansion Board
MSXB 048
-
The MSXB 048 Filtered Analog Input Expansion Board has a four-pole low-pass Butterworth filter on each of its 16 single-ended channels. For DAP applications that require analog filters to take out all above-Nyquist frequencies before signal conversion, it simply replaces the MSXB 037 Analog Input Expansion board. Signal inputs normally connect to the MSXB 048 through a panel-mount DB-37 connector.

Filters

In order to minimize filter roll-off, we start with a quality, highly polished substrate and apply layers of metallization within tight tolerances. Our highly anisotropic ion beam etching process enables us to produce features down to 10 microns. Furthermore, the milling process yields a high consistency from circuit to circuit meaning that whether we produce 1 or 100,000 filters, each one will have consistent filter roll-off characteristics.

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.

Servo And VFD Filters
-
Operation of PWM-driven motors – servo motors and variable frequency drives (VFD) – causes several problems in equipment, including damage to the motor’s bearings due to leakage current causing electrical discharge machining (EDM) and damage to motor’s insulation. PWM motors also are a major source of EMI in equipment. These motor drive systems use pulsed power to drive the motors. As we are aware, the sharp edges of the pulses inevitably include high frequency components which can couple or radiate as noise to other parts of your system and cause unreliability, communication/control problems and EMC compliance issues.
