Narda Safety Test Solutions SRM-3006 field measuring instrument with LTE option

Narda Safety Test Solutions has equipped its SRM-3006 frequency selective field measuring instrument with an LTE option.

The instrument measures the electromagnetic fields emanating from LTE wireless communications stations in their entirety as well as according to cells and antennas automatically.

All the requirements for human and environmental protection are met by the instrument with the LTE option.

The selective radiation meter obtains the LTE-specific information by demodulating control and information channels that are part of the LTE signal. The instrument automatically extracts the cell ID from the primary and secondary sync signals and determines the transmitting antennas from the reference signal.

All the levels of these signals can be shown at the same time and in detail down to each individual antenna. Settable extrapolation factors allow calculation of the field exposure at maximum transmission load.

As a spectrum analyser, the instrument can cover all LTE bandwidths from 1.4 to 20 MHz or select individual frequency channels down to 15 kHz. The instrument displays the continuous time characteristic of the signal level in scope mode, so that the levels of the sync signals PSS and SSS can be identified even though they are present only in a few timeslots. The meter automatically records peak values in level meter mode.

The instrument can automatically evaluate the field exposure in accordance with current human safety standards. Its analysis features also make it suitable for checking signal integrity and for detecting impairments.
