There are a number of challenges to anticipate when testing WLAN 802.11ac power amplifier (PA) modules during design and verification. One of the key challenges is acquiring accurate peak burst measurements of the 802.11ac wide bandwidth signal, which goes up to 160 MHz. When measuring or troubleshooting such a wide bandwidth signal, it is important to select a power measurement instrument with sufficient video bandwidth. This capability ensures that the desired segment of the 802.11ac burst signal can be captured, analyzed and accurately measured.
The appropriate power measurement instrument also allows the analysis of the timing relationship between the control circuitry and the RF burst signal.
