7 Direction Finding Mode
130 IDA-3106 Narda
Table 31: Values displayed in Direction Finding mode
Type Function / Explanation
Peak Displays the instantaneous measured value.
The peak value display (Peak) is held for 480 ms. The value displayed therefore
corresponds to the highest level measured within the last 480 ms. This means that
the numerical display is more stable and the graphical display is smoothed.
RMS Displays the RMS value averaged over a defined period of time. This setting should
be used for constant or fluctuating signals.
The bar next to AVG in the lower status bar indicates the progress of the
measurement until the averaging time is reached. When this time is reached
(complete bar), the instrument refreshes the resulting value using the new
measurement results and discards the oldest results (progressive averaging over
time). Please note that correct direction finding is only possible using a longer
averaging time if the direction of the antenna is also changed correspondingly
slowly.
Max The maximum value (RMS or Peak) that occurred since the start of the
measurement is also shown. The maximum value is shown as a red line in the bar
graph. This display is only possible for Manual Bearing (see section 7.3 on
page 131).
