PHASING TOOL (900MHZ)
8000-2574-22, Rev. A

OPERATING GUIDE

Tip: The transmitter can attract unwanted
attention when placed in a visible area of a mall.
Place a non-metallic item such as a plastic
caution cone over the transmitter to hide it from
view.

You are ready to begin phasing other systems
to the reference signal.

B. Synchronize systems within the

range of the reference transmitter.

1. At the next system, place the sense coil at

or near the transmitter antenna.

2. Verify that you are still receiving a clear

ABC signal from the receiver.

3. Align the system to the reference

transmitter.

While watching the receiver signal and the
system burst on the oscilloscope, adjust the
phase of the system so that the burst starts at
the Falling Edge (beginning) of any one of the
three pulses.

Note: In general, you will want to make a
coarse adjustment with scope at a large scale
(e.g. 500

s or 1ms/division) and then fine tune

the adjustment with the scope at 50

s/division.

4. Attach a sticker to the system indicating the

date that it was phased.

5. Continue phasing all of the systems within

range of the first transmitter signal.

C. Extend the range of the reference

transmitter.

1. Locate a power outlet within the range of

the first transmitter’s signal.

2. Using the receiver, find another channel

with minimal interference.

Power on the receiver and rotate through the 8
available channels (position 0-7 only). Observe
the signal strength indicator and select a
channel with low signal strength.

3. Set up the second transmitter.

a. Set the second transmitter to the same

channel as the receiver.

b. Switch the second transmitter’s signal OFF.

c. Set the switches of the second transmitter

to Normal mode and ABC Signal.

4. Using the oscilloscope, align the second

transmitter.

a. Disconnect the sense coil from the BNC

cable.

b. Attach the BNC cable to the second

transmitter and channel 2 of the
oscilloscope.

c. Switch the receiver back to the same

channel as the first transmitter.

Note: Channel 1 of the oscilloscope is attached

to the output of the receiver.

d. While watching the first and second

transmitters’ signals on the oscilloscope,
adjust the Phase Adjustment pot on the
second transmitter so that the second
transmitter’s signal starts at the Falling
Edge (beginning) of the first transmitter
pulse. Use the “180

Flip” switch if more

adjustment range is needed.

Note: In general, you will want to make a

coarse adjustment with scope at a large
scale (e.g. 500

s or 1ms/division) and then

fine tune the adjustment with the scope at
50

s/division.

5. Verify receiver operation.

a. Turn on the second transmitter’s signal.

b. Switch the receiver channel to the channel

used by the second transmitter and verify
that the receiver signal from the second
transmitter is aligned properly. You can
verify that it is aligned properly by
comparing it with systems phased
previously using the scope and sense coil.

Continue phasing systems as described in Step B.
No timing adjustment are required because of the
second transmitter.

Remove the first transmitter and use it as
necessary to extend beyond the range of the last
transmitter location and so on. Each time you
setup a new transmitter, you must realign the new
signal with the current reference signal as done in
step C.
