BEIJING DAZE TECHNOLOGY · ZHINAN

EMC equipment is only useful when the whole measurement works.

ZHINAN is the product brand of Beijing Daze Technology. We connect instruments, transducers, mechanical structures and test methods into systems engineers can explain, repeat and support.

FROM COMPONENT TO COMPLETE CHAINBuilt around the test method.

50+ years

Technical heritage

Radio-instrument and EMC engineering experience carried into practical measurement systems.

80+

Products and configurations

Sources, receivers, antennas, probes, networks, fixtures and complete system platforms.

CNAS L9727

Accredited capability

Laboratory recognition to ISO/IEC 17025:2017 supports a disciplined measurement culture.

9 kHz–70 GHz

Portfolio coverage

Equipment chains spanning conducted and radiated emissions, immunity and shielding work.

OUR APPROACH

Start with the field, cable, enclosure and applicable method. Then build the instrument chain around them.

WHAT WE BUILD

Capability across the measurement chain.

From one probe to a large-format field-generation platform, the same engineering logic carries through.

Instrument development

EMC sources, receivers, monitoring instruments and dedicated measurement electronics.

System integration

Complete chains built around the test method instead of an isolated component list.

Application hardware

Antennas, probes, clamps, networks, fixtures and mechanical structures for the real setup.

Shielding expertise

Acceptance testing, monitoring and diagnostics for rooms, enclosures and shielded structures.

ENGINEERING ROADMAP

Three decades of turning field problems into test methods.

The product range has expanded, but the operating principle has stayed consistent: measure clearly, document the chain and make the result repeatable.

1993

Company foundation

Beijing Daze Technology begins its independent engineering path.

The company was established on technical experience from Beijing’s radio-instrument industry, combining instrument development with practical EMC engineering.

2007

Focused R&D

Shielding-effectiveness measurement becomes a core research direction.

Daze developed equipment and methods for shielding materials, rooms and smaller enclosures, moving acceptance work toward repeatable, documented measurements.

2013

Field capability

Portable verification and continuous monitoring expand the product scope.

Products such as ZN1690C and ZN1690D extended shielding work beyond formal acceptance tests to cabinets, shelters, tents and long-term monitoring.

2017

Broader portfolio

The equipment chain grows across conducted and radiated EMC testing.

Conducted-immunity systems, loop antennas, active antennas, biconical antennas and log-periodic antennas entered more laboratories and application sites.

2023

From invention to method

Patented measurement ideas advance into formal standardization work.

Research in small-enclosure shielding, suppression-network measurement and shielded-cable attenuation continues to turn recurring field problems into defined test methods.

Today

International platform

Products, standards and application support are being connected for global users.

The international catalog now maps ZHINAN equipment to IEC, CISPR, ISO, IEEE and MIL-STD workflows, with English documentation and direct application support.

MEASUREMENT CULTURE

Traceable results begin with disciplined test design.

We treat calibration, fixtures, cable routing, test-point definition and repeatability as part of the product. The goal is not merely to generate or receive a signal, but to support a measurement that can be explained and repeated.
