Functions and features
In contrast with other instruments, the six
sensors of the ESM “RadMan” independently
monitor all the components of the electric and
magnetic fields of a signal. This means the
device can always measure the strongest field
component. ESM “RadMan” measures
isotropically, i.e. non-directionally.
International and national bodies have set
different limit values for permissible
electromagnetic radiation levels in various
standards and regulations. Different versions
of ESM “RadMan” are available to cover these
differences (see page 56).
Power is supplied from two standard batteries,
giving a typical operating time of 200 hours.
A wide range of accessories ensures that the
unit can be optimized for each particular type
of application.
