1 Introduction
Narda SRM-3006 7
1.2.3 Cables
Narda Safety Test Solutions supplies two cables for the connection between
the antenna and the Basic Unit. Both cables are suitable for the frequency
range between 9 kHz and 6 GHz. The cables are 1.5 m and 5 m long and
contain ferrite to reduce the effect of the external field on the measurement
results. The cables include a control cable along with the RF conductor. This
control cable is connected to the Basic Unit by a multi-pin connector, and
transfers the antenna parameters (type, serial number, calibration date, list
of attenuation factors) to the Basic Unit so that the SRM-3006 can recognize
and use this data. This cable also allows the SRM-3006 to control
successive measurement of each of the three axes to determine the
isotropic result, or selection of a single axis to determine directional
information.
Commercially-available cables can also be used for the connection between
the Basic Unit and the antenna. However, three axis antennas cannot be
controlled using such cables.
Note: Existing cables with a frequency range from 100 kHz to 3 GHz can
be modified for use at frequencies between 9 kHz and 6 GHz. This
modification is free of charge when performed in conjunction with a
calibration. You can get further information from one of our Sales
Partners in your locality or from our homepage www.narda-sts.de
