TIMER LOGGING (TL)
Time-controlled broadband measurement of field strength values in a definable period of
time. With the RMS detector type, all measured values (samples) acquired in a measure-
ment interval are condensed into isotropic min/avg/max values that characterize the
measurement interval. With the peak detector type (BFD-400 only), the acquired mea-
sured values (samples) are compressed to an isotropic max
value.
⇒ See 8.4 TIMER LOGGING on page 71.
SPECTRUM (SP)
FFT analysis of the measurement signal in the selected frequency range with display of
the frequency spectrum, frequency marker evaluation and display of the broadband
level. With the % unit selected, a normalized representation of the frequency response is
shown, related to the limit values of a selected standard.
⇒ See 8.5 SPECTRUM on page 78.
SHAPED TIME DOMAIN (ST)
Evaluation method in the time domain for the gapless recording of the weighted peak or
RMS values with display of the exposure index in % related to a selectable personal pro-
tection standard. Whether the peak or RMS detector is used is defined in the measure-
ment method standards IEC/EN 62233 for household appliances (Weighted RMS) or
IEC/EN 62311 for other appliances (Weighted Peak).
