Stuart, As a side note, I've seen an FCC application where the second harmonic of the device was measured and reported to be at the limit (i.e. 54 dBuV/m). Since the second harmonic was the closest to the limit, the transmitter's power had been increased to a point at which there was zero margin (questionable philosophy considering manufacturing variabilities, I know). The limit is the limit, right?? Unfortunately, 54 dBuV/m is technically greater than 500 uV/m and the FCC wouldn't certify the device. I only make these comments since you have been using 54 and 74 dB in your postings...

Answer is no(IMO). If the idea is to be able to take peak measurements instead of average measurements to expedite the test, then I suggest you take your peak measurements and compare them to average limits. If the peak measurement meets both the calculated peak limit(5000 uv/m) and the stated average limit(500uv/m), then there is no need to make the average measurement. If, however, the peak measurement meets only the peak limit, you are still obligated to take an average measurement and compare it to the average limit. The stated limit always takes precedence over any derived limits. ~~~~~~~~~~~~~~~~~~~~~ Sam Wismer Lead Regulatory Engineer/ Radio Approvals Engineer LXE, Inc.

I left that last part out in the previous question.
