A digital channel sounder has been built to perform measurements of radio channels targeted for 3G and 802.1 la operating at 2 and 5 GHz. The novel aspect of the architecture used is that a completely digital wideband modulator and demodulator has been built to allow extensive use of digital signal processing. Such an architecture results in an instrument with significant flexibility, short measurement durations, a rapid update rate and the ability to automatically acquire time and frequency lock.
