The TE1000 RF Impedance Analyzer operates by generating an RF signal at a user defined frequency in the range 500kHz to 150MHz, and injecting it into the load at the probe tip. The resultant RF voltage and current are sampled and measured, and from this 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 rectangular 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 or a crystal.
The TE1000 can be controlled either via the keypads 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 from the TE1000 and store this in a format which is compatible with MS Excel.
