(a) A digital product is being tested for compliance to CISPR 22 Class A requirements. The receiving antenna is placed a distance of 30 m away and is attached to a 50 V receiver with a 100 ft length of 50 Ω cable that has a loss of 10 dB/100 ft at 300 MHz as shown in Figure above. If the receiver indicates a level of -64.5 dBm at 300 MHz, and the antenna provides 4 V at its base for every 1 V/m of electric field incident on it determine whether the product passes or fails and by how much.
(b) List the information required on a Declaration of Conformity.
(c) FCC and the CISPR have classified products into class A and Class B.
(i) Explicit the terms FCC and CISPR? (ii) Which local organization would be equivalent to the FCC? (iii) What sorts of products are classified under Class A and Class B?
(d) Classify the given products within Class A or Class B digital device with regard to the regulatory tests that they must comply with.
(i) network server (ii) $5000 U.S. high-speed, high-capacity laser printer (iii) tablet PC (iv) 3G smart phone (v) Wireless Access Point
(e) Distinguish between harmonized and non-harmonized standards.
