current mode

a shaker amplifier mode in which the output current of the amplifier and thus the shaker force is proportional to the input voltage signal. This is in contrast to voltage mode in which the output voltage and thus the shaker output velocity is proportional to input voltage.

Microdot

  1. A defunct connector manufacturer which is now a brand owned by the company TE Connectivity (previously Tyco Electronics).
  2. A 10-32 coaxial connector made by that company.

The Microdot brand has many connector styles and sizes but in the sound and vibration field, the term microdot usually refers to a coaxial 10-32 (#10 gauge, 32 threads per inch) threaded connector. It is prevalent in accelerometers, charge amplifiers, and 1/4" IEPE microphone preamplifiers.

voltage mode

  1. a shaker amplifier mode in which the output voltage of the amplifier and thus the shaker velocity is proportional to the input voltage signal. This is in contrast to Current Mode in which the output current and thus the shaker output force is proportional to input voltage.
  2. another term for an IEPE accelerometer. This should not be confused with an accelerometer without built-in electronics connected to an external voltage amplifier.
