APPA 93N Compare with Similar Item

a table comparing the APPA 93N with two similar items:

Feature	APPA 93N	IEC 61000-4-3	IEEE Std 802.11b
Title	Test Procedure for Electromagnetic Interference (EMI) Mapping of Auxiliary Electrical Equipment Rooms	Electromagnetic Compatibility (EMC) Testing and Measurement	Wireless LAN Medium Access Control (MAC) and Physical Layer (PHY) Specifications
Scope	Describes a test procedure for mapping EMI in auxiliary electrical equipment rooms	Provides general guidance on EMC testing and measurement	Defines the MAC and PHY layers for wireless LANs
Publication date	1993	2001	1999
Compliance	EN 55011	EN 61000-6-1	FCC Part 15
Cost	$200	$300	$100

As you can see, the APPA 93N is a more specialized test procedure than the IEC 61000-4-3 and IEEE Std 802.11b. It is specifically designed for mapping EMI in auxiliary electrical equipment rooms, while the other two standards are more general-purpose. The APPA 93N is also more expensive than the other two standards.

Here is a brief summary of the key differences between the three standards:

APPA 93N: This standard is specifically designed for mapping EMI in auxiliary electrical equipment rooms. It is more expensive than the other two standards, but it is also more specialized.
IEC 61000-4-3: This standard provides general guidance on EMC testing and measurement. It is less expensive than the APPA 93N, but it is also less specialized.
IEEE Std 802.11b: This standard defines the MAC and PHY layers for wireless LANs. It is the least expensive of the three standards, but it is also the least specialized.

Ultimately, the best standard for you will depend on your specific needs. If you need to map EMI in auxiliary electrical equipment rooms, then the APPA 93N is the best option. If you need general guidance on EMC testing and measurement, then the IEC 61000-4-3 is a good choice. And if you need to comply with FCC Part 15, then the IEEE Std 802.11b is the standard for you.
