Selecting 802.11b/g DSSS/CCK/PBCC Demodulation

(option B7R only)

Sets the VSA to demodulate IEEE Institute of Electrical and Electronics Engineers. A US-based membership organisation that includes engineers, scientists, and students in electronics and related fields. The IEEE developed the 802 series wired and wireless LAN standards. Visit the IEEE at http://www.ieee.org 802.11b/g 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)./CCK complementary code keying/PBCC packet binary convolutional code modulated signals.

After selecting the demodulator, the configuration parameters must be set up. Select the Standard Preset or configure the VSA manually from the 802.11b/g Demod Properties dialog box.

Reviewing the Setting up a Measurement topic is also recommended.

Example recordings

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