Flexible a nd optional calibration types, compatible with multiple calibration kits
3672 Series of Vector Network Analyzers provide multiple calibration types, including guided calibration
(automatic calibration), unguided calibration using mechanical calibration kit to conduct through response
calibration, through response & isolation calibration, single port calibration, enhanced response calibration,
full two port SOLT calibration, TRL calibration and electronic calibration (E Cal) etc. Users can select
calibration kits, such as coaxial 3.5mm calibration kit and electronic calibration kit based on test
requirements, which greatly facilitates testing on devices with different interfaces.

Multiple windows to display all measuring channels
The analyzers possess functions of multi-channel and multi-window display, support up to 64 channels.
Maximum 16 measuring windows can be simultaneously displayed, and each window can simultaneously
display up to 8 test traces, which makes the observation results more visible and the operation more

Large dynamic range
3672 Series of Vector Network Analyzers are designed with the concept of mixer receiving, which
effectively extends the dynamic range of the complete machine and meets the test demand for large
dynamic range.

Low trace noise, high test accuracy
The excellent performance of 3672 Series of Vector Network Analyzers in trace noise highly improves the
test accuracy so as to meet users demand for accurate measurement, and it is especially helpful for the
accurate measurement of devices with low insertion loss.

Time domain analysis can comprehensively characterize the design
With time domain options, 3672 Series of Vector Network Analyzers can realize the switching of
measurement results between frequency domain and time domain, which can be used to identify the
discontinuous points of devices, fixtures or cables to realize accurate fault location.
