Displaying an Unknown Signal with
Connect-and-View™
The Connect-and-View™ function enables hands-off
operation to display complex unknown signals. This
function optimizes the position, range, time base, and
triggering and assures a stable display on nearly all
waveforms. If the signal changes, the setup will track
these changes.
To enable the Connect-and-View™ function, do the
following:
• Connect the red test lead from red Input A to the
unknown signal to be measured
Perform an Auto Set.
Certain details of the waveform can be made visible by
manually changing amplitude, time base, waveform
position, and triggering. How to do that is explained in the
course of this Guide.
Freezing the Screen
You can freeze the screen (Waveforms and Readings)
with the HOLD/RUN key. This allows you read the screen
while the Test Tool has been disconnected from the
Device to be checked.
Freeze the screen. HOLD appears in
the bottom of the reading screen.
Start the measurement again.
Scope Measurements on Input A and B
Choose frequency measurement (Hz) for Input A:
Open the INPUT A Menu.
Highlight Hz.
Press ENTER to confirm the selection.
Observe that Hz is now the Main Reading. The former
Main Reading has now moved to the smaller Secondary
Reading Position. Figure 5 shows this.
