Probe Operating Information
Bandwidth Limit Button and
Indicators
Press the button to limit the probe bandwidth
to 5 MHz. 5 MHz is close to the switching
frequency of most switching transistors
(FETs) in switch mode power supplies
(SMPS).
The 5 MHz filter assists in the characterization
and testing of power supplies in switch mode
by removing all high frequency content, noise
and harmonics from the measurement.
Press the button again to return to the Full
position, which selects the full specified
bandwidth of the probe.
Audible Overrange On/Off Button
and Indicators
Press the button to light the ON LED and
enable an audible alarm that indicates when
the measured signal exceeds the selected
range. Press the button again to light the
OFF LED and disable the audible feature.
