 The Python drivers of the Sivers library require Python 2. One way to remove this dependence is to remotely control the Sivers array with an HTTP server. We can start the HTTP server as follows,
 {{{#!shell-session
-root@srv1-in1:~/mmwsdr/host/mmwsdr/array$ python ederarray.py --unit SN0240
-}}}
-{{{#!shell-session
-root@srv1-in2:~/mmwsdr/host/mmwsdr/array$ python ederarray.py --unit SN0243
-}}}

-- '''twonode.py:''' In this demo we control two single SDR node. We create and SDR object and an XY-Table object for each node using the `mmwsdr` library. The SDR object configures and controls a Xilinx RFSoC ZCU111 eval board and a Sivers IMA transceiver board. A user can provide arguments to the script, such as the carrier frequency, the COSMOS node id and the transceiver mode. The script by default starts a local and a remote connection with the SDR.
- 1. Start the remote Eder server on the :
-{{{#!shell-session
-root@srv1-in1:~/mmwsdr/host/mmwsdr/array$ python ederarray.py --unit SN0240
-}}}
- 2. Start the experiment on the local server:
-{{{#!shell-session
-root@srv1-in2:~/mmwsdr/host/demos/basic$ python twonode.py --freq 60.48e9 --mode tx
+root@srv1-in1:~/mmwsdr/host/mmwsdr/array$ python ederarray.py -u SN0240

The SDR object configures and controls a Xilinx RFSoC ZCU111 eval board and a Sivers IMA transceiver board. Shown below are the commands to start an HTTP server on srv1-in1 and to run twonode.py script on srv1-in2. twonode.py script in this case connects directly to its local Sivers front-end SN0240 and it connects to SN0243 via the HTTP server running on srv1-in2.

 === Channel Sounder ===
 In this demo, we show a frequency-domain channel sounder at 60 GHz. We generate N_FFT symbols in
-frequency-domain. We generate a wide-band sequence filling [sc_min, sc_max] sub-carries with random 4-QAM symbols. We

 use IFFT to get the time-domain TX sequence. We transmit the data from SDR1 with cyclic repeat. We receive 100 frames
 of N_FFT data from SDR2. The user can select to save or process the data. When we process the data
