Chapter VIII Vector Voltage Measurement Mode (Optional)
The S5105D/E/F Vector Voltage Measurement Mode (VVM) is a convenient tool for phase matching of
RF cables, which is mainly used to measure the electrical length of cables or other kits under test.
This mode can directly replace a vector voltmeter and has the same flexible and convenient
operation interface as the vector voltmeter. The results of the single port measurement electrical
length are displayed in amplitude and phase format, but the results of the dual port measurement
electrical length are only displayed in amplitude format.
As shown in the figure (a), measuring the electrical length of the kit under test with a vector voltmeter
requires a directional coupler and a signal source to transmit the fixed carrier frequency.
In the figure (b) below, the signal source and directional coupler are integrated into one instrument.
Therefore, the kit under test can be directly connected through the RF output port of the S5105D/E/F
and are tested directly without any external devices.

Section 1 Basic Operations
This Section will briefly introduce the vector voltage measurement mode (VVM) measurement function
and method of the S5105D/E/F microwave analyzer, so that the first-time users can have a
general understanding of the test operation process and make basic measurements after reading this
section.

2 Set Frequency Span
Before performing the vector voltage measurement, set the frequency value of the point frequency signal
to be tested. The frequency range of the S5105D/E/F microwave analyzer in vector voltage
measurement mode is 30kHz - 18GHz (S5105D), 30kHz - 26.5GHz (S5105E), 50MHz - 40GHz
(S5105F). The frequency range should be met during the setting, the corresponding button operations
are as follows:
