Selecting the 802.11a/g/j/p OFDM Demodulator

(option B7R only)

Sets the VSA to demodulate 802.11a/g/j/p OFDM Orthogonal Frequency Division Multiplexing: OFDM employs multiple overlapping radio frequency carriers, each operating at a carefully chosen frequency that is Orthogonal to the others, to produce a transmission scheme that supports higher bit rates due to parallel channel operation. OFDM is an alternative tranmission scheme to DSSS and FHSS. (Orthogonal Frequency Division Multiplexing) modulated signals that conform to OFDM standard formats.

The IEEE developed the 802 series wired and wireless LAN standards. Visit the IEEE at http://www.ieee.org 802.11g modulation see OFDM Overview.

After selecting the demodulator, set the configuration parameters. One of the available Standard Presets can be selected or parameters can be manually set them from the 802.11a/g/j/p Demod Properties dialog box.

Example recordings

The 89600 VSA includes several example 802.11 signals that can be used to help you learn how to use the IEEE 802.11a/g/j/p OFDM demodulator. The included signals are listed in the Demo and Recorded Signals topic in the Getting Started book.
