Thanks for the information and clarification.
What about narrow band signals such as frequency hoppers where the bandwidth
is at most 1MHz? These signals are well within the RBW range of most spectrum

Hello Sam,
The diode detector is used to trigger the envelope of the signal. Actually
this diode has to be used to determine the power output of the unit since the
802.11(b) would have BW around 10 MHz( the duty cycle would be used to correct

Hi All,
Section 7.2.1.2 step 1 seems to be a method of determining the duty cycle of
the EUT. This step calls for a diode detector for the measurement. My quick
research shows this to be a fairly expensive accessory piece of equipment. I
have a

The National Electronics Manufacturing Association is a trade
organization. The NEMA ratings that you refer to are from
ANSI/NEMA standard 250. NEMA does not test products.
UL has UL 50 (Enclosures for Electrical Equipment) and they use

The NEMA ( www.nema.org) ratings are tested and self-certified by the
