2FSK Measurement
Description
2FSK is a binary FSK (frequency shift keying)
form of modulation. 2FSK is commonly used to
transmit data where an FSK modulated signal
is composed of two different frequencies, one
frequency represents the “1” data and the other
frequency represents the “0” data.
For 2FSK measurement 2 traces will be created,
one trace will show the 2FSK spectrum (trace 1,
yellow) and the other trace (trace 2, purple) will
show a MAX HOLD trace type with peak
markers at the FSK carrier and hop frequencies.
