ASK/FSK modulation analysis (Option DMA)

Optional ASK/FSK modulation analysis is now available. Amplitude Shift Keying

(ASK) is used in RFID and optical systems. Frequency Shift Keying (FSK) is used

in many applications including cordless phone, paging system and RFID.

N9340B with option DMA supports 4 display modes: Symbol, Waveform,

ASK/FSK Error, and Eye Diagram. Included is Pass/Fail testing of higher than

carrier power, higher than ASK modulation depth/FSK frequency deviation,

lower than ASK modulation depth/FSK frequency deviation and higher than

FSK frequency deviation. The metrics you need are shown, including carrier

power, ASK/FSK error, ASK depth/FSK frequency deviation, and ASK index etc.

For reports and future measurements the waveform with metrics and setup

parameters can be saved.

The Eye Diagram of ASK also shows the

metrics with detailed parameters.

The Waveform of FSK also shows the

metrics with detailed parameters.
