The TE3000, TE3001 and TE3002 vector impedance analyzers are versatile, portable test instruments which enable the user to make highly accurate impedance measurements from Low Frequencies (LF) through Very High Frequencies (VHF).
The TE3000-series of RF vector network analyzers have full vector measurement capability, and accurately resolves the resistive, capacitive and inductive components of a load. The user can display the vector impedance plus a range of related parameters including SWR, reflection coefficient, return loss and R-L-C equivalent circuit.
The TE3000, TE3001 and TE3002 impedance analyzers are ideally suited for precision bench testing and development, making it a superior alternative to portable VSWR meters and antenna testers which can only provide a fraction of this information. The TE3000 has a test cable port, while the TE3001 has a single 50 Ohm input. The TE3002 is a dual port 50 Ohm device.
The TE3000-series impedance analyzers operate from 0.03 MHz-300 MHz. All also include signal generator capability with a general purpose RF test signal output across this frequency range. These lab precision units are rugged, lightweight and can be powered by mains or by internal battery making it ideally suited for both benchtop and portable use. An internal data display provides stand alone visual output. The unit's RS232/USB interface and PC based software further increase the power of the instrument. These features provide swept frequency capability and facilities for complex data analysis, data logging and graphical display on a convenient laptop or other computer. The units are supplied in a lightweight, rugged aluminum case.
The TE3000-series RF network analyzers offer similar functionality and comparable accuracy over its radio frequency range as the HP/Agilent 4193A and other "high end" lab instruments, at a fraction of the cost.

How the TE3000/3001 Work: The TE3000/3001 operate by generating an RF signal at a user defined frequency in the range 30kHz to 300MHz, and injecting it into the load. The resultant RF voltage and current are sampled and measured, and from the unit calculates the complex impedance of the load. Once the complex impedance is known, the VSWR, reflection coefficient, R-L-C equivalent circuit and return loss can also be determined. The user selects which measurement is to be displayed and in which format. The impedance can be displayed in rectang ular or polar format. The R-L-C equivalent circuit can be displayed as either a series or parallel circuit.
There are 2 basic modes of operation. In fixed frequency mode one frequency only is selected by the user. In scan mode the user can scan sequentially through a range of frequencies. The scan mode is particularly useful for locating resonances such as in a quarter wave line, tuned circuit, or a crystal.
These instruments can be controlled either via a keypad on the front panel or remotely from a PC using the RS232 serial line and control software. The PC software can be used to log data directly from the impedance analyzer and store this in a format which is compatible with MS Excel.

The TE3000 and TE 3001 RF impedance analyzer is capable of extremely accurate measurements of a wide range of impedances. However, as with any high frequency measurement, a certain amount of care must be taken to ensure that the results are not "contaminated" by stray impedances. Always observe the following precautions when using the TE3000 series (or any other impedance analyzer):
• Minimize any lead lengths between the probe and the impedance to be measured. Even a few millimetres of wire can be significant when measuring low impedances at high frequencies.
• Connect the load as close as possible to the base of the probe tip. This is the point which the TE3000 series imepdance meter uses as its reference.
• Avoid having any excess lead length "hanging off" the probe tip: such lead length acts as a small antenna and appears as a capacitor in parallel with the impedance being measured. This can be significant when measuring high impedances at high frequencies.
• Keep your fingers clear of the probe tip when making a measurement. Hold the probe body and earth ring only.
*When measuring in or around high power RF sources, ensure that no stray RF enters the probe.
Connect the TE3000 or TE3001 antenna impedance analyzer to the cable, and terminate the cable with a "perfect" reflector - an open circuit is usually the easiest. If the total electrical length of the cable is less than one half-wavelength then the angle of the reflection coefficient (in polar format) is twice the electrical length of the cable:
Electrical length in degrees = angle of reflection coefficient / 2
Furthermore, if the velocity factor, Fc, of the cable is known then the physical length of the cable can be calculated from:
Physical length = ( electrical length in degrees x Fc x 3 x 10 8 ) / (360 x frequency in Hz )
For example, if the reflection coefficient is 0.5<40° then the cable is electrically 20° long. If the velocity factor of the cable is 0.66 and the frequency is 10MHz, then the cable is physically 1.1 metres long.
Application: Measuring the loss in a length of coaxial cable
