6 Common Functions
104 IDA-3106 Narda
NOTE: It is best to use units of field strength (e.g. dBµV/m) so that the level values
can be compared even if different antennas are used. Avoid changing the
measurement units unnecessarily. Since conversion between Table 26 and
Table 27 is not possible, you must use the same units selected for a
localization from start to finish.
To change the units:
The top menu level of the operating mode is displayed.
1. Press the Display softkey, them press the Unit softkey.
2. Use the rotary control knob to highlight the desired unit and press the OK
key.
The selected unit is saved.
