I’m a new user of a BB60C – and I purchased it specifically to be able to show a Wi-Fi signal changing modulation techniques in real time.
I am more than a bit confused with all the options. What I want to do is just show a 20MHz OFDM on Channel 36 and then use the built-in WLAN 802.11a/b/n/ac Analysis Mode to see Wi-Fi traffic in real time.
The instructions say something about “easiest way” by using sweep measurement mode… HOW?
Are there any step by step instructions for configuring Signal Hound to be on a specific WLAN channel?

Using our software there are a couple things you need to know about the signal before you can make a WLAN measurement. You need to know the center frequency, modulation type (A/B/N/AC), and signal level. The suggestion to use sweep mode is to help customers who may not know the center frequency. If you already know the channel, you can select it in the frequency control group in WLAN meas mode. Channel 36 can be found under the 5GHz Ch. drop down menu. Then you need to know the signal level to set the trigger level. You should use the AM vs time (search) plot to set the correct trigger level. This plot runs even if no signal is found and can be used to monitor the AM levels over time. You want to set the trigger level between the noise floor and the signal on level. Too low and you will always trigger on noise, too high and you will always get the trigger not found message. Finally, you need to set the Standard. If you know it, great, otherwise trial and error is an easy option.
I’m going to follow up via email as well. Let me know if you have follow up questions.
