Standard (802.11a/g/j/p OFDM)

Default: See OFDM Standard Presets Table

Standard sets the demodulator to one of these standard 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. modulation formats:

This does not set the configuration parameters. Use the Preset to Standard button to automatically configure the demodulation parameters.

IEEE 802.11g DSSS Direct sequence spread spectrum. The data transmission scheme (sometimes referred to as a "'modulation" scheme) used in 802.11b WLANs. DSSS uses a radio transmitter operating at a fixed centre frequency, but using a relatively broad range of frequencies, to spread data transmissions over a fixed range of the frequency band. 802.11a and 802.11g (when not operating in 802.11b mode) use Orthogonal Frequency Division Multiplexing (OFDM).-OFDM	IEEE Std 802.11g - 2003

IEEE 802.11g modulation

The IEEE 802.11g standard defines both single-carrier and OFDM modulation formats. The single-carrier modulation formats are compatible with 802.11b and can be demodulated using the 802.11b/g DSSS/CCK complementary code keying/PBCC packet binary convolutional code demodulation mode (see About Opt B7R: WLAN-DSSS/CCK/PBCC 802.11b/g)

IEEE 802.11g defines two different OFDM modulation formats. One, which is mandatory in 802.11g, is an exact copy of the 802.11a format except that the carrier frequencies are in the 2.4 GHz Gigahertz: A frequency measurement which equals one billion hertz. band. We refer to this as "IEEE 802.11g OFDM". The other OFDM format is an optional format called DSSS-OFDM that combines an 802.11b-style single-carrier preamble with an 802.11a-style OFDM data payload. We refer to this as "IEEE 802.11g DSSS-OFDM". The 802.11a/g/j/p OFDM modulation analysis mode can demodulate and analyze either of these OFDM formats.
