Transmitter configuration and testing

Configuration and acceptance testing of broadcast transmission equipment for both FM radio and DVB-T is a speciality.

At right is a collection of test equipment from 1978 in use testing a TV transmitter. Modern test equipment is indeed considerably more integrated. Axino-Tech is one of the few consultancies remaining with expertise of analogue TV; still in use for MATV systems, security and elsewhere.

Appliance electrical testing

Appliances can be checked for safety, power consumption and power quality.

Axino-Tech can provide checks of consumption, quality and safety, although we are not an accredited laboratory. Small appliances and energy saver lamps can be very unfriendly to the power grid, making it important to check power factor and harmonics of current.

Customised product tests from simple performance checks to full consumer type testing including ease of use assessments.


Further to the above, Axino-Tech can provide advice about TV and FM reception, technicalities of broadcast transmission in N.Z plus assistance with setting up of broadcast transmission facilities. We may be able to help analyse RF interference problems and even build prototype radio-frequency filters (usually below 1GHz), to prove a solution works before committing.
