Signal amplifier 3222

PXI cardrack-mountwide-band

Model 3222 is a 3U single-slot, PXI-based power amplifier designed for signal amplification. Offering unmatched signal purity, Model 3222 amplifies signals from dc to over 20 MHz. The unit has a fixed gain of x10, however, the same amplifier is available with custom gain, with no signal purity or performance degradation. Single-width PXI card Low distortion Custom Configuration of: Gain, Input Impedance, Output Impedance, Output Polarity, Signal Ground Features Solves Common Problems A common problem with PXI equipment is the inability to produce high voltages resulting from low power supply rails. For example, waveform generators or similar signal source devices draw power from 12V rails. Consequently, they cannot produce signals above 10Vp-p into 50Ω. Model 3222 solves this problem by using DC/DC converters to increase rail voltages which, along with custom components and unique design, enable amplification of input signals to 40Vp-p into high impedance, or 20Vp-p into 50Ω Allows Full Current Rating to Other Devices The power amplifier draws current only from the +5V rail, leaving the other power supply rails free to supply their full current rating to other devices. Ground Level Model 3222 can be supplied with input and output connectors that are isolated from case ground allowing the amplifier to float from case ground level up to 250Vdc. The only limitation is that the both the input and output grounds must connect to the same ground level. This capability is extremely important in applications where the amplifying device must reside on the same ground level as its source.
