ESD electrostatic discharge
EXTSTROBE* external strobe signal
F
F farad—a measurement unit of capacitance
FIFO first-in first-out memory buffer—the first data stored is the first data sent
to the acceptor; often used on DAQ devices to temporarily store incoming
or outgoing data until that data can be retrieved or output
floating signal sources signal sources, including batteries, transformers, or thermocouples, with
voltage signals that are not connected to an absolute reference or system
ground; also called nonreferenced signal sources
FPGA field programmable gate array
FREQ_OUT frequency output signal
G
gain the factor by which a signal is amplified, sometimes expressed in decibels
GATE gate signal
GPCTR general-purpose counter signal
GPCTR0_GATE general-purpose counter 0 gate signal
GPCTR0_OUT general-purpose counter 0 output signal
GPCTR0_SOURCE general-purpose counter 0 clock source signal
GPCTR0_UP_DOWN general-purpose counter 0 up down signal
GPCTR1_GATE general-purpose counter 1 gate signal
