固定频率滤波器系统

model 39000 hydrophone signal conditioner
our model 39000 hydrophone analog signal conditioning/filter system provides up to 210 channels of fully programmable hydrophone signal conditioning. the 39000 15-slot rugged mainframe has a variety of high performance filter/amplifier plug-in cards to choose from with characteristics such as low-pass and band-pass functions, as well as, three traditional filter response types of butterworth, bessel and elliptic. the 39000 system is ideal for conditioning low-level voltage signal inputs in front of high-resolution data acquisition systems.

model flx-3007 filter/amplifier signal conditioner
the new krohn-hite model flx-3007 flexible instrumentation chassis provides a rugged, low cost, flexible platform for up to 7 high performance instruments sharing the same compact chassis. with the flx-3007 chassis, you get the functionality and features needed from a broad and growing selection of plug-in cards, avoiding the costs associated with larger systems that are not needed. the flx-3007 platform can be assembled with up to 7 plug-in cards that you specify. it can be configured into a single channel signal conditioner or it can be expanded into a channel management system when needed; and since all flx plug-in cards are all compatible, adding new cards is easy and economical. side-by-side rack mounting is also available when high channel count is needed in a 5.25” x 19” rack spacing.
