+In this section we will review and construct basic signals. For this tutorial, use the Y option when calling doing SSH. First you are going to want to resolve a space on SB3 before continuing on with the tutorial.
+{{{
+ssh -Y username@sb3.orbit-lab.org
+}}}
+
+Check that the nodes are powered ON:
+
+{{{
+omf stat -t all
+}}}
+
+If one or both of the nodes are in a powered off state turn them on with:
+
+{{{
+omf tell -a on -t all
+}}}
+
+Next to get the latest updated image with updated gnuradio libraries enter:
+
+{{{
+omf load -t all -i ubuntu-14-04-64bit-sdr-full.ndz
+}}}
+
+After calling the nodes will power down after imaging. Turn them back on and enter:
+
+{{{
+ssh -Y root@node1-1
+}}}
+
+*Note if this doesn't work the first time, the node might be recovering from imaging. Wait a few seconds and try again.
+
+Enter on the command line:
+
+{{{
+gnuradio-companion &
+}}}
+
+From the available blocks construct the schematic displayed in:
+[[Image(sawtoothbuild.png)]] this will allow you to view the signal and its frequency plot equivalent similar to the image below:
