An automatic vector voltmeter may be built using a six-port junction[1] on the principle that a reference signal ([a.
Three steps required for the use of the vector voltmeter are the six-port junction calibration, the insertion device calibration and the measurement, based on the superposition principle.
A schematic diagram of the vector voltmeter is shown in Figure 4.
The use of the vector voltmeter as an automatic network analyzer for a given frequency[14] involves performing the system calibration without the component under test, the direct link between the two insertion points A and B, as shown in Figure 8; computing the calibration coefficients [C.
The cost of the analyzer system is less than that of systems that employ vector voltmeters and frequency downconverters.
Versatile, the VNA Master is also an all-in-one tool that can replace laboratory grade instruments, such as scalar analyzers, vector voltmeters, power meters and spectrum analyzers, in the field.
Features include cable and antenna test (distance to fault, return loss, and VSWR); a vector voltmeter (one-and two-channel); power meter measurements up to 24 GHz with a USB power sensor; USB, LAN, and micro SD connectivity; and a wide-angle and bright display for use in direct sunlight.
Its key measurements include cable and antenna test from 2 MHz to 4/6 GHz, spectrum analysis from 100 kHz to 4/6 GHz, vector network analysis, vector voltmeter and true average power measurements.
