7.1.20 RESP - Frequency Response

WHERE USED

The frequency response test, RESP, may be used to check that the variation in power loss of a telecommunications or audio transformer over a specified frequency range is less than specified limits.

MEASUREMENT CONDITIONS


The RESP test consists of a number of Insertion Loss (ILOS) tests repeated at different frequencies.

The resistors shown are fitted to the test fixture and should be switched out of circuit when making other measurements such as resistance and inductance. This can be done by fitting relays to the fixture and switching them at appropriate points in the test program using OUT tests.

The first ILOS test is made at a reference frequency that is usually near the middle of the band of frequencies of interest. The result of this test is the 0dB reference level. Further ILOS tests are then carried out at user selected frequencies and the results referred to the reference dB level.

If all the referred ILOS results are at or inside the specified limits, the result of a RESP test is the referred ILOS result that is closest to the limit. If any of the referred ILOS results are outside the specified limits, the RESP result is the referred ILOS result that is furthest away from the limit.
