## How to use the RF simulator options
Add the following options to the command line to enable the channel model and the IQ samples saving for future replay:
```bash
--rfsimulator.options chanmod,saviq
```
or just:
```bash
--rfsimulator.options chanmod
```
to enable the channel model.
set the model with:
```bash
--rfsimulator.modelname AWGN
```
Example run:
```bash
sudo RFSIMULATOR=server ./nr-softmodem -O ../../../targets/PROJECTS/GENERIC-LTE-EPC/CONF/gnb.band78.tm1.106PRB.usrpn300.conf --parallel-config PARALLEL_SINGLE_THREAD --rfsim --phy-test --rfsimulator.options chanmod --rfsimulator.modelname AWGN

```
# Real time control and monitoring
Add the `--telnetsrv` option to the command line. Then in a new shell, connect to the telnet server, example:
```bash
telnet 127.0.0.1 9090
```
once connected it is possible to monitor the current status:
```bash
channelmod show current
```
see the available channel models:
```bash
channelmod show predef
```
or modify the channel model, for example setting a new model:
```bash
rfsimu setmodel AWGN
```
setting the pathloss, etc...:
```bash
channelmod modify <channelid> <param> <value>
channelmod modify 0 ploss 15
```
where:
```bash
<param name> can be one of "riceanf", "aoa", "randaoa", "ploss", "offset", "forgetf"
```
