The Agilent 70138A Vector Voltmeter is a dual-channel, auto ranging, receiver which measures the voltages of two CW signals and the phase difference between them. The measurements can be of a single channel or the ratio between the two channels, and results can be displayed as voltage or power (in linear or log units), normalized magnitude and phase angle, or real and imaginary components. In addition, the Agilent 70138A has built-in procedures for simple network analysis. The Agilent 70138A has two configurations-the first providing two high impedance probe inputs with a frequency range from 100 kHz to 1 GHz, and the second providing two 50ohm type-N connector inputs with a frequency range from 100 kHz to 2 GHz. The configuration can be changed by replacing the instrument's input module.
The Agilent 70138A is a component of the Agilent 70000 Modular Measurement System that can be used in any application where CW vector signal information is required-particularly in the design, manufacture or service of RF assemblies. The Agilent 70138A is a high-sensitivity receiver and can be used with any source, including Agilent 7000 MMS system source, a tracking generator, or one that is part of the device to be tested.
Typical measurements include voltage, power, gain or loss, impedance and phase matching. Measurements can be made either from the input to the output of the device, or by probing within the device. Other measurements include transmission and reflection-procedures that include test system calibration against known standards.
