Its powerful microprocessor processes commands in 40 microseconds (10 times faster than Galil's prior generation), accepts 22 megahertz encoder inputs, and updates servos at 32
kilohertz. The controller incorporates two Galil D3040 four-axis, 500-watt drives with outputs of 20-80 volts and up to 10 amps per axis.
The electromagnetic spectrum we are most familiar with is a finite collection of frequencies between about 3,000 cycles per second (
kilohertz), or 3 kHz, and 300 billion cycles per second (gigahertz), or 300 GHz.
Wireless systems perform over a wide range of frequencies, from a few
kilohertz to high frequency gigahertz systems.
The ability to perceive a sound depends on both the frequency (
kilohertz) and strength (decibels) of the sound.
The recording format we use is wave 48
kilohertz (kHz) 24 bits, which is a grade higher than audio compact disc (CD) quality.
In addition to implementation challenges, almost all SFT measurements of circuits operating at more than a few
kilohertz cannot be made while the board under test is physically connected to the ICT bed-of-nails fixture, resulting in the requirement for dual-level test fixturing (see dual-leveling fixturing sidebar).
Unlike prox cards that operate at 125
kilohertz (kHz), smart cards operate at a much higher frequency: 13.56 megahertz (MHz).
