+Adding a channel
+===============
+
+After adding a system, a telescope and a laser to the database, you need to add a new channel.
+To do this, click on the **HOI channels** in the *System settings* panel.
+This will take you to a page with a list of all availabe channels that are connected with your lidar systems.
+This list should be empty if this is the first time you add a system.
+
+To add a new channel to the database click on **Add HOI channel** at the top right of the screen.
+This will take you to a new page were you can fill in the needed information. As before, the fields in **bold**
+are mandatory and you will need to fill them before you can save you new system.
+
+The fileds you have to fill here are more, as many of these are used during the processing of measurements.
+
+.. warning::
+
+ There is a last step, different from the previous cases, when saving a new channel. You need to connect your channel with
+ a lidar system before you save, or else all your entry will be lost. Read carefully through this document (or directly
+ the :ref:`last section <connect-channel-to-system>`) to avoid any problems.
+
+
+Fill in the fields
+------------------
+
+To start using the single calculus chain you will need to fill the following fields:
+
+Name
+ The name of the channel ex. "355", "1064 analog" etc.
+
+Telescope
+ The telescope that is used for this channel
+
+Laser
+ The laser that is used for this channel
+
+Interference filter center
+ The center of the interference filter in nm
+
+Interference filter FWHM
+ The FWHM of the interference filter in nm
+
+Emission wavelength
+ The emission wavelength of the laser used for this channel
+
+Field of view
+ The field of view realated to this channel in mrad
+
+Raw range resolution
+ The raw range resolution of the measured data in m
+
+Dead time
+ The dead of the detector in ns. You should fill in this in case
+ of a photon counting detector.
+
+Trigger delay
+ The trigger delay value for the channel in ns. Fill in 0 if not needed.
+
+Scattering mechanism
+ The scattering mechanism that is involved in this channel. Select the appropriate value from the drop-down list.
+
+Dead time correction type
+ The dead time correction type to be applied. Select *Not defined* if none needs to be defined.
+
+Background mode
+ The way to calculate the singal background. Select *Not defined* if none needs to be defined.
+
+Signal type
+ The type of the singal that is measured, ex. "elT" for total elastic, "vrRN2" for vibrational-rotational
+ Raman signal from Nitrogen melecules etc. See :ref:`signal-types` for details.
+
+Detection mode
+ The detection mode of this channel.
+
+.. _connect-channel-to-system:
+
+Connecting to a system
+----------------------
+
+Before you finish, you need to attach your channel to one of your systems. To do this, go at the bottom of the page and
+select your system from the drop-down list in the **System channels** area.
+
+When you are done, press the **save** button at the bottom right of the page.
+This will take you back to the list of your channels.
+If everything went OK your new channel you just added should appear in the list.
