The TE1000 was originally developed by Tomco Technologies (formally Tomco Electronics) in 2002 as a side line to their main business – RF amplifiers.

The aim was to fill a gap in the market for a low-cost accurate impedance measurement device in the MF-HF-VHF range. Tomco has since gone on to become world leaders in RF Amplifier technology, and use the TE1000 extensively throughout their workshop, as taking RF impedance measurements is an integral part of designing and constructing components in an RF amplifier. The original construction included a plastic probe with an injection moulded body and this was later replaced by the nickel plated brass body in current production. The brass body improves grounding and reduced interference to the signals returning to the unit. Numerous improvements were made as Tomco enhanced and expanded the TE1000’s capabilities to meet the unique needs of their customers. Revisions G and H of the two main boards inside the TE1000 unit are the culmination of 8 years of refinement to provide faster, more accurate and stable impedance measurements. The addition of the USB adaptor in 2005 enabled users without RS232 ports to still access the versatile range of interface options. In 2005 Tomco outsourced assembly of the TE1000 to TrewMac Systems. In late 2009 TrewMac acquired the full manufacture and sales rights to the TE1000.

With 4 years of experience assembling and calibrating units and 16 years experience in RF and related electronics, TrewMac is now looking to the future with plans to enhance the existing features of the TE1000 even further.

Our immediate goals are to:

Increase the frequency range

Include the distance to fault function

Provide graphical on board display
