| The eZLab Impedance Analyzer is a reliable impedance measurement solution. In most applications, especially scanning the ultrasound transducer impedance, it is a low cost alternative of HP4294. The box has three BNC connectors with one for impedance testing, and the other two for two channels of sinusoidal signal output with adjustable phase difference. This device is designed with state-of-the-art direct digital synthesis (DDS) technology. The impedance accuracy is determined by the quality of calibration terminals and the system circuit leakage. If the device under testing has impedance above 1k ohm, the frequency locations of the peaks and troughs of the impedance curve will still be correct but the absolute impedance value may be lower than its true value. |
