This means that the output power will stay at the same level, but the script may change TX gain to trade it with digital gain and also change RX gain. -As a first test you can run the main script without parameters. It preserves the output power and generates all available visualization plots in the newly created logging directory `/tmp/dpd_<time_stamp>`. As the script should increase the preak to shoulder ratio, tune the txgain in a way to be able to see a the change. For example to a ratio of -30dB. You can do this using the telnet remote control from `odr-dabmod`. To run it do following: +As a first test you can run the main script with the *--plot* parameter. It preserves the output power and generates all available visualization plots in the newly created logging directory `/tmp/dpd_<time_stamp>`.

You can do this using the telnet remote control from `odr-dabmod`. To run it do following: ``` cd dpd -python main.py +python main.py --plot ``` Each plot is stored to the logging directory under a filename containing its time stamp and its label.
