This repository is a script toolbox to interact with RF tools like the RF Power Monitor 8000 or the RF Explorer.
The scripts in the repo use python 3.X and are meant to be used from a Linux machine. The best way to set up the work environment is using virtualenv. You will also need python-tk.
sudo apt-get install python-tk
sudo pip install virtualenv
Then prepare your workspace:
git clone https://github.com/xoseperez/rf-tools
cd rf-tools
virtualenv --python=python3.5 .env
. ./.env/bin/activate
pip install -r requirements.txt
And you are ready to go...
The Power Monitor 8000 is an RF power monitor with a wide range (up to 8GHz) and impressive quality for it's price. You can read more about it in my post about RF power monitor tools on the cheap.
The pm8000.py script reads the data from the Power Monitor 8000 via USB port and dumps it in a CSV like style with a timestamp and the amplitude of the signal. You can set the center frequency (integer, MHz) and offset (float, dB) form the command line.
$ python pm8000.py -f 169 -o -20.0

The rfexplorer.py script allows you to get data from you RF Explorer Handheld Spectrum Analyzer in different ways. The first thing you can do is to get the help from the device:
$ python rfexplorer.py -h
usage: rfexplorer.py [-h] [-m {peak,swipe,plot}] [-r] [-c FREQ_CENTER]
[-s FREQ_SPAN] [-d DURATION] [-p PORT]
optional arguments:
-h, --help show this help message and exit
-m {peak,swipe,plot} output mode
-r reset RF Explorer
-c FREQ_CENTER frequency center
-s FREQ_SPAN frequency span
-d DURATION monitor for these many seconds
-p PORT USB port to use, otherwise will try to find it
Usage examples:
Monitor and print peaks from 862.5 to 873.7 for 60 seconds
python rfexplorer.py -c 868.1 -s 11.2 -t 60
Plot range of frequencies in real time
python rfexplorer.py -m plot

The three different modes have different outputs. The peak mode is the default one and it's equivalent to the one in the pm8000 script above:
$ python rfexplorer.py
