The detector features optical (LED) and acoustic (piezo
speaker) indication.
The brightness of the indicator LED and the pitch of
the audible tone will increase proportionally with the strength of the
detected signal, making it simple and easy to locate the interference
source. |
The ERD-1500 covers a frequency range
approximately 50 Hz to 1500 MHz, with a typical sensitivity of 25µV/cm (500
MHz, far field setting).
Power is supplied by two 12V batteries (A23, MN21 or
GP23A, not included).
The sliding switch on the side of the unit has three
positions: off (middle position), high sensitivity (far field) and low
sensitivity (near field).
The WiNRADiO ERD-1500 Electromagnetic
Radiation Detector is ideally suited for the following applications:
-
Tracing sources
of electromagnetic interference (EMI)
-
Surveillance
countermeasures (detection of "bugs")
-
EMC
(electromagnetic compatibility) pre-testing
-
Quick safety radiation check of transmitters and appliances
-
Installation
and set-up of computer-based radio monitoring systems

One of the typical applications of the ERD-1500
is to locate sources of electromagnetic interference.
Light dimmers are known sources of interference, owing
to their use of solid-state switching circuits. Some brands are worse
offenders than others. A faulty dimmer such as the one shown here may
turn into a wide-band interference generator causing considerable
degradation of radio and TV reception. |

The sales of bugging devices are booming and there is
overwhelming evidence of their wide-spread use. You can never be sure
until you bug-sweep your premises with an ERD-1500.
Surveillance countermeasures is yet another important application of
this unit.
In the pictured situation, a radio surveillance device
is hidden in a house intercom. Miniature transmitting devices may be
hidden in many objects of daily use. Thanks to its wide frequency range,
sensitivity and fast response time, the ERD-1500 can be
successfully used to locate most types of bugging devices. |
