Model 901HS High Sensitivity

ESD Event Detector

Electrostatic discharge (ESD) events are important indicators of

excessive charge accumulation in environments where they may be

detrimental to manufacturing processes in the semiconductor or LCD

industries.

Trek’s Model 901HS is a diagnostic tool used to identify

incidents or verify suspected areas of ESD activity.

Electromagnetic waves, generated by electrostatic discharge,

transmit differently in different environments. In order to

accommodate these differences, the Model 901HS includes two

antennas - one active and one passive - that can be used for

detection purposes. The determination of which antenna to use

will typically be based on the environment in which it’s being

deployed and the level of detection that is required.

The active antenna may be connected directly to the Model

901HS or with an extension cable that lengthens the antenna to

1.5 meters. It provides high flexibility in positioning the antenna to

achieve the best possible reception. The active antenna can

detect ESD events as small as 10 V, at a distance of 50 mm. A

passive, monopole antenna is also provided. This antenna has a

detection capability that identifies ESD events as small as 50 V, at

a distance of 90 mm and is generally used when less sensitive

detection is required.

When an ESD event is detected, the Model 901 signals the

operator by playing an audible notification tone and by displaying

the detected event level visually via its five LED lights. Since

measurement results will vary due to the distance from the signal

source and whether there are physical obstacles present in the

environment, the LED display indicates a relative signal strength

rather than an actual signal strength. A stereo connector on the

Model 901 enables connection to an optional external display

device to display the measurement results.
