Firstly, the meter is robust.  Encased in a high impact, corrosion resistant, brushed aluminium housing that will withstand the impact that a satellite meter often endures when used in a professional installation environment.  The buttons are responsive and there is no need to press them down hard to change settings..  The meter features a USB port for software upgrades if necessary, A video out port for displaying the video screen on an external monitor.  12VDC input and F connector satellite signal input are standard.  On the top front face there are 8 signal LEDs that light up to indicate signal quality when the satellite is found.  

Operation:
The meter is turned on by pressing the red power button for several seconds until the screen flashes blue.  It will then start up.  Pressing MENU will bring up the following screen:

As you can see from this screen, you can select various pre-installed satellites that can be found within the Asia Pacific region.  Satellites can be added or removed from the list if needed.  The meter can be used for C and KU band satellites.

Next, you can choose the LNB type from the list by pressing OK on LNB TYPE and moving down to the LNB local oscillator that you are using on the particular installation.  In our case, we are using a 10.700GHz LNB.

If using only one dish, leave it on Port A as per screenshot.

Next, we choose the frequency we are aligning to.  Choose a frequency that you know is broadcast from the satellite you are chasing.  In our example, we are aligning to Optus C1 and using the Austar frequency 12.305GHz which carries the EXPO channel.  As this frequency is not in our default list, we can simply add a new one.

Now we have signal quality of 84%.  We can use this screen to align the dish and LNB for maximum signal quality, as well as signal to noise ratio (S/N) and bit error rate (BER).  The Xtra-S will also give you Sat co-ordinates such as 156 degrees.  This is the longitude of the satellite.

From this point on, we can switch to spectrum view and see the carriers.  This is absolutely essential for aligning motorised dishes.  As the dish moves across the satellite arc, the carriers of each transponder from each satellite can be viewed and peaked up on this screen.  Furthermore, the  spectrum is a live view and updates as quick as spectum view on satellite meters valued at much more.  The spectrum view of the Optus C1 satellite can be seen below.  Note on the left of the spectrum are the lower Optus D3 frequencies and on the right are the higher range Optus C1 frequencies.
