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.

This wideband designs supports one or two independent channels of PCM with data rates up to 20Mbps. The unit includes both an optional FM demodulated output for PCM data, and standard programmable AM/linear AGC outputs for auto-tracking receivers. The design offers 8 IF Bandwidths and 8 Video Filters per channel for each receiver.AC coupling with a low pass filter is employed to ensure a high quality data link with long strings of NRZ-L ones or zeroes. The unit provides a software selectable 10 MHz reference I/O port forlocking local oscillators to a high precision external source or to arrange multiple units in a master/slave arrangement. The receiver’s control and status is achieved via Ethernet, USB or auto-switched RS-232 (or “4-wire” RS-485 in place of 232). When utilizing the RS-422 interface, multi-drop configurations can be accommodated.

Low Voltage DC / Battery Powered HV Amplifiers
WMA-01 And WMA-01LF
The Falco Systems WMA-01 is a high voltage amplifier that runs from an 24 - 30V DC power supply and can be battery powered if required, e.g. for use in a Faraday cage. Its internal high voltage generator is inductor-free and hence does not spread magnetic interference in sensitive experimental setups. The output noise is impressively low at 3mVrms. For extremely low noise applications where bandwidth is not an issue, a dedicated WMA-01LF version is available that contains an output low pass filter capacitor which reduces the bandwidth to 50Hz, but makes the noise drop to below 0.1mVrms. This bandwidth-limited amplifier is ideal for MEMS or piezo positioning with manual voltage adjustment.
