Program Composition
EMI pre-compatible (radiation) near-field
measurement solution
Necessity of near field measurement
Far field measurements have some limitations and it is impossible to know the source of
serious radiation
problems. In this case, we can use a spectrum analyzer and a near-field probe to locate
the transmitted
interference source and the near-field measurement by near-field measurement. The
near-field measurement
is a relative measurement, which means it needs to test the product under test. The
results are compared
with measurements from third-party certification laboratories to predict the likelihood
that the product
under test will pass the conformance test.
Positioning interference sources and
transmission routes
-
Scan a specific frequency band using a spectrum analyzer and a near field probe.
- Determining the spectral characteristics of the interferer.
-
According to the measurement results, locate the propagation path of the
interference source and
evaluate the rectification effect.
Program Composition
Low power measurement solution
The solution uses a high-dynamic range of seamless range switching technology. Powered
colleagues can
continuously acquire and measure very large
dynamic range currents from nA to A, with resolutions up to 28 bits and sampling
intervals as low as
20μS.

Wireless charging transmission efficiency measurement scheme
Power transfer efficiency is a key performance factor for WPT systems. Keysight ENA Series
Network
Analyzers
offer the following solutions.
-
Analysis of real-time voltage, current and power transfer efficiency of WPT systems
with 50Ω
S-parameter measurements
-
The user can also define any load impedance to simulate the power transfer
efficiency after
connecting the battery.
-
The measurement results of resistance (R), reactance (X) and frequency (f) can be
presented in two
or three dimensions, helping users to more easily understand the correlation of
load impedance.
