3.4 Muffer Command (Environment
Analyzer)
The muffer module is used to analyze the electromagnetic environment.
Syntax:
muffer IFNAME [-tXX] [-lXX] review [FREQ1 [FREQ2 ...]]
| { mac[2|3]|mynet|scan [MAC]}
muffer IFNAME sensor [record=SEC] [F1 [F2] [BW STEP]]
muffer IFNAME sensor [replay]
muffer stat [clear]
Description:
The muffer module makes it possible to rapidly test the electromagnetic
environment, visually estimate the efficiency of the utilization of the air links,
reveal sources of interference, and estimate their power.
Several operating regimes of the muffer module provide for different levels of
details in test results.
3.4.1 Review Mode
This regime is enabled by the review option. It makes possible to have a general
estimation of emissions and interference within specified frequency range. Up to 7
frequencies (separated by spaces) subject to analysis may be specified as
parameters [FREQ1 [FREQ2 ...]. Only two last digits of the frequency values shall
be given.
Example:
muffer rf5.0 review
CAUTION
Normal operation of a radio module is impossible when this regime is enabled.
The "muffer" command output in "review" mode is limited by text session window size.
