Group,
what are the current test lab practices to evaluate "sensitive frequencies" as
specified in 61000-4-3? It is fair to assume what some of the "sensitive
frequencies" will be missed with 1% step, especially in higher range.
Some of the big telco's have dedicated procedures on how to treat sensitive or
frequencies of key interest ("foki") with dedicated levels, dwell times, 50kHz
steps and so on. But it feels like an uphill battle to convince the labs and to
explain the procedure, which brings up the suspicion what there are not much of
"sensitive frequencies" evaluations going on.
This fits in ongoing discussion about field uniformity and calibration
procedures. If you need to investigate individual frequencies, you should
calibrate the field at these frequencies.
How about 'external' frequencies sources, such as LTE or any other mobile
communications? should they not be tested separately or just hope they get
addressed during the sweep?
Any opinions on test methodologies, besides traditional sweep are welcome.
Thanks,
