Until recently, the vast majority of vibration testing has been conducted on a single exciter
that would impart translational motion to the test payload in a single mechanical degree of freedom (1-DOF).
Prototypes of the rotational eccentric mass (REM) exciter
were designed and built.
A new DVB-S/DVB-S2 satellite receiver module, modelled after successful Harris satellite IRD products, lets broadcasters download satellite content and feed it directly into the exciter
without external device requirements.
The maximum output voltage of the exciter
(ceiling voltage) depends on the input ac voltage.
Thus, the impedance of the panel and exciter
can be dimensioned to offset roll-off in the panel's stiffness controlled region.
Gahan's voice has certainly matured over the years, displaying greater resonance as they ran through much of their latest album, Exciter
- a varied mix of electronic and acoustic sounds - from the guitar twanging Dream On to the melancholy Freelove and When the Body Speaks.
The Sweetest Condition and When The Body Speaks from Exciter
were warmly received but the night really got under way when Depeche Mode went deeper into their archives by playing fans' favourites from the Black Celebration and Violator albums.
Twenty years on, they are in the middle of a sell-out world tour, which arrives at Wembley this week, and have a new album, Exciter
, to promote.
25 mm flat panels powered by a 12V exciter
to generate 250 to 20,000 Hz reproduction.
NXT's basic technology creates sound from flat surfaces, but traditionally the exciter
- which causes the surface to vibrate, creating sound - has been in the middle of the surface.
The probe's RF exciter
units use butyl o-rings to seal the internal electronics from the Jupiter atmosphere up to a design pressure of 2 MPa.
In addition, Exelis will improve the technology on the exciter
- the component that generates jamming signals.
