Abstract :
A network analyzer system employing a digital phase modulation and linear frequency conversion of the test signal is described. The system makes use of a microcomputer as a key component and operates as a precise RF-vector voltmeter over the full X-band (8.0-12.4 GHz) without the need for calibration standards. Measurement results for an insertion-loss range of up to 65 dB are presented.
