9.3.4 Setting the measurement range (Meas. Range)
Level Recorder • Meas. Range
The sensitivity of the system depends on the setting of the input attenuator,
which is determined by the Measurement Range parameter. A high
measurement sensitivity setting avoids falsification of the result due to
intrinsic noise. On the other hand, it is important that the instrument is not
overdriven. Such overloading can also be caused by signals that are outside
the frequency range of the service you want to measure, e.g. from a
powerful radio transmitter although you are only measuring mobile phone
signals.
To set the measurement range:
⇒ See Setting the measurement range (Meas. Range) on page 72.
Note: The measurement range setting defines the maximum value
indicated by the bar graph (right-hand limit of bar frame).
9.3.5 Selecting the result type (Result Type)
Level Recorder • Result Type
In contrast with other operating modes, the Result Type menu in
Level Recorder mode allows selection of the detector type, i.e. Peak and
RMS. The following can be displayed:
• Peak only
•RMS only
• Peak and RMS
