6.3.2 Automatic measurement range search
(MR Search)
Safety Evaluation • Meas. Range • MR Search
This softkey initiates a search for a suitable measurement range. This is
recommended if the field situation is unknown.
⇒ Press the MR Search softkey.
ª The message: Searching for best measurement range. Please
wait. is displayed. A measurement over the entire frequency range
covered by the antenna you are using is made in the background.
This takes several seconds. When it is completed, the device sets the
measurement range to the optimum value automatically and reverts
to normal measurement mode.
Note: Press the ESC key if you want to cancel the process.
MR Search Type
The SRM-3006 provides two types of measurement range search which can
be selected using the MR Search Type softkey (toggle function):
• Normal: This type is suitable for all largely static signals.
• Conserv.: This type allows for a higher overload reserve. It is better to set
the measurement range manually if pulsed signals are being measured.
To select the search type:
⇒ Press the MR Search Type softkey.
ª The switch toggles between the two types each time the softkey is
pressed.
6.3.3 Measurement input overload
If the signal level is higher than the range that can be measured, the warning
message OVERDRIVEN is shown in the display (in the part above the lower
status line, next to the axis setting).
