Versatile and dependable，Type4808incorporates a design based on magnetic-alloy technology to produce excitation.This exciter is suitable for a variety of research and educational applications that include vibration testing of small objects，measuring mechanical impedance and studying structural response。
Type4808has a wide frequency range（5Hz-10kHz），a peak-to-peak displacement of 12.7mm（0.5in）and can deliver peak sine forces of up to 187N（42lbf）with assisted air-cooling or up to 112N（25lbf）without。预应力性能，we recommend pairing this exciter withPower Amplifier Type 2719单击功能区上，but it can also be driven by third-party units。
To meet your specific testing needs，Type4808can be customized with a range of accessories，including
trunnions，power amplifiers，nylon stingers，push-pull rods，force transducers and impedance heads。
