Upper Freq
The function Upper Freq is only visible if the setting
Adjustable is selected in the Filter function.
Set the low cutoff frequency for the filter range here.
Frequencies below this cutoff frequency are blocked.
Damping
This function is used for matching the probe. By setting
the damping level of the probe oscillating circuit you can
vary the height, width, and resolution of the echo dis-
play.
400 Ohms
This setting gives a low damping, the echoes become
higher and broader.
50 Ohms
This setting reduces the echo height but produces nar-
rower echoes with a higher resolution.
Dual Mode
You can toggle between single-element and dual mode.
Off
This setting is for single-element operation. The probe
must be connected to the
T/R socket (see page 53).
On
The dual mode is for using dual-element probes. The re-
ceiver must be connected to the
R socket and the pulser
to the T/R socket (see page 53).
