Test Necessity & Standards

The Set-up Table Influences (TI) test is a critical evaluation designed to determine the subtle influence a set-up table has on field strength measurements. This ensures that the table itself does not contribute unacceptable errors to your test results, which is vital for maintaining compliance integrity.

Accreditation Standard

We perform this evaluation as described in CISPR 16-1-4 (2010), Clause 5.5.2.

Measurement Methodology: Dual-Measurement Integrity

Our precise methodology isolates the table’s influence, providing a direct measurement of its impact on your testing environment.

Procedure: Two-Step Isolation

We conduct two transmission measurements: one with the set-up table present, and the second with the set-up table absent.
During both measurements, the transmit antenna is kept in the same specific arrangement.
The difference between the two measurement results provides a highly accurate estimate of the influence caused solely by the table.

Detailed Frequency Ranges & Measured Results

This specialized test covers a wide range necessary for comprehensive EMC validation and provides actionable, clear data for your records.

Test Parameters

Frequency Range: The test is performed for the 200 MHz to 18 GHz frequency range.
Report Output: Following the test, we issue a report detailing the table value in dB for the following ranges:
- 200 MHz to 1 GHz
- 1 GHz to 6 GHz
- 6 GHz to 18 GHz

Estimating Uncertainty Contribution

One of the most important aspects of this service is its contribution to validating the overall test environment’s reliability.

We calculate the table’s related uncertainty contribution to your field strength measurements, ensuring your compliance reporting is complete and accurate.
