In September of 2009, LBA Technology became an authorized calibration center for the Tomco TE1000 Impedance Analyzer (see referenced story.)  Since that time, manufacturing of the TE1000 was switched from Tomco to Trewmac Systems Pty Ltd.  LBA has now been authorized by Trewmac to repair and recalibrate the TE1000 Impedance Analyzer, including servicing unites that were originally manufactured at Tomco Technologies.  The following letter was sent to LBA Group on 1/25/2011.


To Whom it may concern,

This letter is to assert that:

LBA Group, Inc.
3400 Tupper Drive
Greenville, NC 27834

Have been trained in the repair and recalibration of the TE1000 Impedance Analyzer,
manufactured by TrewMac Systems Pty Ltd. This includes the service of units that were
formally manufactured at Tomco Technologies.

LBA Group have the authority to repair, recalibrate and distribute the TE1000 product to
customers the American continents, and beyond.

Yours Sincerely,

The TE1000 Impedance Analyzer is a precision, portable impedance analyzer that enables the user to make highly accurate impedance measurements through VHF range (0.5-150MHz).

The TE1000 Impedance Analyzer measures vector impedance, SWR, R-L-C equivalent circuit, vector loss coefficient, return loss, 0.5-150MHz

Key features:

•The unit is completely portable for use on the bench or in the field
•Precise vector impedance measurements from 3ohms to 10k-ohms
•Frequency range 0.5MHz to 150MHz
•Directly displays vector impedance, reflection coefficient, SWR, return loss, R-L-C equivalent circuit
•Sophisticated PC based software included to allow data logging, frequency sweeping and a range of graphical displays

Typical uses of the TE1000 Impedance Analyzer include RF engineering design and development, antenna testing and tuning, probe and sensor tuning in NMR systems, impedance matching, component test, cable fault finding, filter design and test, and cutting cables to precise electrical lengths.  LBA ships and supports the TE1000 worldwide!  For more information on repair or recalibration, please contact
