WLAN waveform pattern
Standard
■ WLAN waveform pattern:
The WLAN (IEEE802.11a/b/g) waveform patterns listed in the
table below are provided on the MG3700A internal hard disk.
The signals for testing the receiver/transmitter of a terminal or
module can be output by selecting one of these WLAN
waveform patterns.
