Functionality
The Hand-Held Terminal (HHT) is the centre point of the system and all communication in
the system is with respect to the HHT. The operator can set up parameters for tests, perform the
tests and configure other test settings from the HHT. Below are the explanations of various options
and output screens one can use on the HHT.

Normal Test Modes:
Pre-Test:
A Pre-Test is required before the ‘Test A’ or ‘Test B’ can be performed. The Pre-Test has the
function of sanity checking the link between the HHT and the SAT units. Also performing Pre-Test
will configure the current test settings in SAT units. A test carried out without running a Pre-Test
may NOT present valid results. Any change in the Configuration settings should be followed by a
Pre-Test.

Test A / Test B:
Telegesis Range Finder tests are designed to evaluate the suitability of deployment of a
Smart Energy device which is why they focus on the ZigBee Smart Energy recommended RF
channels in the 2.4GHz spectrum. Tests A and B are performed on ZigBee SE channels 11, 14, 15
and 19 during Test-A, while the remaining of SE channels 20, 24 and 25 are tested in Test-B.
Although the Rangefinder is designed to assist with ZSE installations, the Continuous test
and Energy scan can be used to analyse the entire ZigBee 2.4GHz spectrum.
At the start of each test-A/B, countdown is activated to give a chance for the operator to
put the HHT in place of simulated test device such as electricity meter and move away from the
meter housing if necessary. This timer is configurable in the Configuration Menu.
To perform tests A or B, navigate to the menu item on Menu Screen 1 using and
keys and press button for the test start screen to appear. Continuous and
Figure 8: Test Start Screen
Once the countdown has elapsed, the test starts and the test results are displayed for each
channel for the test as the test progresses. The completion of the test is indicated by a short beep
from the built-in buzzer. The display backlight changes to Red for test failure and to Blue colour if
the test is a pass. Also the failed values will be inverted. For details of the Pass/Fail criteria please
see section “Interpreting Test Results”.

Energy Scan:
The operator can make use of the Energy Scan of the network to get a measure of the noise
or traffic present on a channel. Due to the dynamic nature of protocols (Wi-Fi, Bluetooth, ZigBee)
each scan may show a different noise level even when done back to back. Each channel is scanned
for noise for about 260mS. The results are painted for each channel as they become available.
-35dBm is considered to be very noisy and -85dBm is considered very quiet. The channels
preferred by the ZigBee Smart Energy standard are highlighted in the test results. A sample of the
test screen is shown below. To perform the Energy Scan, navigate to the Energy Scan menu item
on Menu Screen 1 using and keys and press for the energy scan result graph as
shown below to appear on screen.
Figure 10: Energy Scan Screen
(a) A bar representing noise level on a channel, the value ranges from
-85dBm (bottom) to -35dBm (top)
(b) Channel number ‘0’ represents channel 11 of the ZigBee channels, it is
highlighted as it is one of the recommended channels according to the
ZigBee Smart Energy specification
(c) Channel number ‘F’ represents channel 26 of ZigBee channels, it is not
highlighted as it is not one of the channels recommended for use by
ZigBee Smart Energy specification
(d) A tick mark as legend indicates that shorter bars indicate low noise
level on a channel

Continuous Test Modes:
Tx Tone
The Transmit Tone option can be useful in situations in which one has to test immunity of the
existing ZigBee network against noise from other devices operating on the same channel. This
option will transmit a continuous tone on the user selected channel and power level. To transmit a
tone on a channel, navigate to the Tx Tone menu option on menu screen 2 using and keys
and press for following screen to appear.
Figure 11: Tx tone
Once on this screen, the user can scroll through parameters using the and keys, press
to be able to edit the transmit power and channel number on which to transmit a continuous tone
which can be done using the and keys and again press to set the new value.
After setting all the parameters, user will navigate to START option and press to start
transmitting the tone. The symbol on the right will start blinking to indicate that the tone is being
transmitted on the set channel.

Ch Ping
This is another continuous mode tests which can be used whenever the user wants to find
the best location to position the SAT-A and SAT-B units to get the optimum signal strength that can
be achieved.
The main advantage of this test is the ability to set different test parameters such as Tx
Power and RSSI threshold limits in all three (SAT-A; SAT-B and HHT) devices. This gives the
operator flexibility to emulate different devices with different settings which can be the case in an
actual ZigBee network.
This option can be used to measure the RSSI between the HHT and the SAT-A and/or SAT-
B units. As with the other options navigate to the Ch Ping option on menu screen-2 using and
keys and select the option using key. The single channel Ping Config screen as shown
above will appear. There are different parameters as shown in the figure above which are to be set
according to test requirements. To scroll through list of parameters, use and arrow keys.
Press to edit, and to edit values and again press to set the parameter value for the
continuous Ping test to be performed.

One Hop Test
The One Hop test is a very useful test in systems that require a repeater in between two
nodes. The SAT-A will operate as a repeater (RTR) between the HHT and SAT-B. All messages
from the HHT which are directed towards SAT-B will be relayed by the RTR. This test will help
finding the best possible location for the repeater to be placed and simultaneously tests the link
between nodes through the repeater. The following configuration screen is displayed when the one
hop test option is selected. The configuration screen allows the operator to modify the test
parameters like Tx Power, RSSI threshold, Channel used for test and the duration of test. To scroll
through list of parameters, use and arrow keys. Press to edit, and to edit
values and then press to set the parameter value for the current session of test.
Once parameters are set navigate to the start button on the screen and press to start
the test. At this point the one hop results screen as shown below will be displayed on screen.
