Located in the picturesque Adelaide hills, TrewMac Systems began in August 2005 with a core team of experienced industry professionals. Specialising in RF electronics, associated metal work, and the manufacture, calibration and repair of the original TE1000 Impedance Analyser, TrewMac Systems has continued to grow and excel with distribution centres in 4 different countries, servicing customers all around the world..
Trwmac network analyser for the professional, and the novice user, these units are simple and intuitive to operate while providing a host of powerful features and functions to suit any task.
Cable tuning, crystal characterisation, antenna tuning or component characterisation can all be performed on battery power in the field without the need for a computer. The new custom SOL calibration feature allows the user to move the measurement reference plane to the end of any transmission line, or to remove the effects of test jigs and cables connecting the device under test. With user selectable averaging and a vast array of display formats, get your data fast and in the format you need now.
All of our analysers are supplied in a rugged aluminium carry case with a custom foam insert and come as a complete kit ready to use.
Use a USB or serial cable to connect your analyser to a PC and experience a new world of data analysis. With features like time domain reflectometery, distance to fault, multi series plotting, difference from reference plotting, smith chart plotting, Zo and VF functions you can analyse the data you need in the minimum time with superb accuracy.

The TE1000 Vector Impedance Analyzer has enjoyed more than 20 years as a popular choice for obtaining impedance measurements at RF frequencies by hundreds of customers around the world. It is a precision, portable impedance analyzer which enables the user to make highly accurate impedance measurements through VHF range (0.5-150MHz). Although superseded somewhat by the recent addition of the TE3000 the TE1000 is still available in its original build format and specifications. See the comparison table for reference. The TE1000 has full vector measurement capability, and accurately resolves the resistive, capacitive and inductive components of a load. The user can display impedance in polar form, rectangular form, series R-L-C equivalent or parallel R-L-C equivalent circuit. On board algorithms generate a range of related parameters including VSWR, complex reflection coefficient, and return loss against a user defined characteristic impedance Zo (normally 50 Ohms). The TE1000 uses an RS232 interface and is supplied with a third part serial to USB converter for connection to a PC. It shares the same software as the new TE3000 series providing swept frequency capability and facilities for complex data analysis, data logging and graphical display. Any application capable of comm port control can send commands and receive data from the TE1000 making it perfect for automated and remote data collection. The Trewmac Systems TE-1000 Vector Impedance Analyzer is supplied in a lightweight, rugged aluminium case with all the accessories included to operate the unit to its full potential. The unit itself can be powered by the mains adapter or by the internal battery making it ideally suited for both bench top and portable use. Typical applications include RF design and development, antenna testing and tuning, impedance matching, component testing, cable fault finding, filter design and testing, and cutting cables to precise electrical lengths.
The TE3000 is a versatile RF measurement tool for the professional, the educator and the novice. It is easy and intuitive to use and does not require user calibration. Measurements can be taken at the tip of the probe, much like an oscilloscope, or the unit can re-calibrated to the end of a coaxial cable, or the optional tweezer attachment. The TE3000 Vector Impedance Analyser is an improved portable desktop instrument designed for very high accuracy impedance measurement. It boasts a larger frequency range with smaller resolution and faster data rates than its predecessor - the TE1000. The oscilloscope style probe style construction and user variable output signal make it ideal for 'in circuit' impedance characterisation of small signal devices without the risk of damage to the DUT. These types of measurements can be very difficult to obtain using a normal VNA. An N type adaptor is also supplied with the unit allowing direct connection to an N type female connector for standard network analysis. The unit is supplied factory calibrated to the tip of the probe, and is self checking on start up. This feature means the unit is ready to use straight out of the box and does not require recalibration until the recommended period has elapsed. For the advanced user, several calibration kits are available to custom calibrate out the effects of test jigs and coaxial cables. The user can then switch between factory and custom cal at will. The TE3000 software provides a powerful set of formats and charts for fast analysis, and interfaces with a simple USB. Features include smith charts, multi series plotting, difference plotting, curve smoothing, velocity factor, electrical length, characteristic impedance, and time domain reflectometry. Results may be saved and retrieved, or opened in excel.
The TE3001 One Port Vector Network Analyser is built for the field professional who understands the calibration process and has a network analysis task to perform. The TE3001 is supplied with an N type male connector interface for standard network analysis. The unit features a larger output signal than the TE3000 for excellent noise immunity in noisy environments. It's supplied with a 3 piece male and 3 piece female calibration kit allowing the user to remove the effect of any linear test fixture or transmission line, and provide an unprecedented level of measurement accuracy. A tweezer attachment and associated calibration kit is available for component or crystal characterisation. With user variable averaging, a vast array of display formats and battery or mains power the TE3001 is ideal for broadcast and plasma applications where field and workshop measurements are required. To compliment this construction, the TE3001 software provides a powerful set of formats and charts for fast analysis, and interfaces with a simple USB. Features include smith charts, multi series plotting, difference plotting, curve smoothing, annotations, cursors, time domain reflectometry and interference spectrum scanning.
