To set the video bandwidth:
1. Press the VBW softkey, followed by the VBW softkey.
ª The Select Video Bandwidth (VBW) entry box opens.
2. Use the rotary control to select the desired setting and press the OK key.
ª The selected value is applied.

time).
6.3 Setting the measurement range
(Meas. Range)
Safety Evaluation • Meas. Range
Spectrum Analysis • Meas. Range
Level Recorder • Meas. Range
UMTS • Meas. Range
Scope • Meas. Range
To set the measurement range:
⇒ Press the Meas. Range softkey.
You can now select the measurement range as follows:
• Manual measurement range selection
• Automatic measurement range search (MR Search)
Background information:
The sensitivity of the system depends on the input attenuator setting.
This setting is determined by the Measurement Range (MR) parameter.
High measurement sensitivity avoids falsification of the results due to
noise generated internally by the device. On the other hand, it is
important that the device is not overloaded (saturated). Saturation can
also be caused by signals outside the frequency band of the services
being measured (shown under Others), e.g. high power radio
transmitters when measuring mobile telephone signals.
