SuperBroom Plus TA – Operating Manual

OPERATION

ASIC

ESCRIPTION

The Type Approved Super Broom is a frequency agile

non-linear junction detector utilising Dynamic Channel

allocation. There are a total of 19 channels available

within the operating band of 869.4 – 869.65MHz. When

SuperBroom is switched on the receivers are calibrated.

The ambient RF Background is measured and a search

algorithm selects 10 RF channels for optimum operation. This

ensures that potential interfering signals are avoided, thereby

reducing false triggering.

Note If you are not familiar with the principles of detection using

Harmonic Radar or Non-linear Junction Detection you may

wish to read the Theory of Operation section later in this

manual before attempting to actually use SuperBroom.

REQUENCY

OPPING

ODE

When either EU-Low or EU-High is selected during start

up, the unit will automatically hop around the optimum 10

channels at 1 minute intervals.

Note 1 Frequency plan is given in the appendices.

Note 2 when Non-EU is selected at start up, the Optimum Tx

channel is selected, frequency hopping is disabled, detect

function enabled and the unit is no longer EU compliant.

Caution Operation in this un-license mode is the responsibility of

the user.

OWER

ODE

SuperBroom can be used in one of two power control

modes. The power mode is selected using the Listen/Mode

button on the front panel.

LISTEN / MODE

The function of this button depends on which signal source

is selected. When the Compare button is selected this button

acts as the Mode button as described below. When 2nd or

3rd signal sources are selected this button acts as the Listen

button as described below

Listen

Selects Listen audio output, this allows you to listen to the

returned signal via an Amplitude Modulation detector. If

the target is, for example, an electronic timer with an audio

frequency clock signal then the electronic clock may be

heard as a regular sound when LISTEN is selected.

Mode

Toggles between the default MAN (manual power control)

and DSP (Digital Signal Processing) automatic power control.

The current power mode is indicated on the bottom line of

the LCD display. When in DSP mode the decimal point on

the single character LED display on the antenna head fl ashes

to indicate this mode has been selected.

Note 1 During start up in the 'Set Tx power' menu this button

(listen) sets the maximum TX power to 500mW (EU high

power setting).

DETECT / (B

When the Compare button is selected this button toggles the

LCD back-light On and Off. This button operates the Detect

function only under the following conditions:

Note 1 During start up in the 'Set Tx Power' menu, this button

(detect) selects the Non EU option. This enables the rotary TX

output power control (9) for the operator to set power, please

refer to Appendix B for guidance.

In Non EU operation the Optimum Tx channel is selected,

frequency hopping is disabled, detect function enabled and

the unit is no longer EU compliant.
