NOTE. At some temperatures, there may be extraneous data points after the first
half cycle when viewing the front-panel Internal Clock output (as is done in this
step). This behavior may also occur when viewing multiple cycles in TDR mode.
In both cases, this behavior is normal.
HRotating the Horizontal SCALE knob clockwise expands the waveform
on-screen (more horizontal divisions per waveform period), counter-
clockwise rotation contracts it, and returning the horizontal scale to
1s/div returns the period to about five divisions. Leave the time base
set to 1 s/div.
HThe horizontal POSITION knob positions the signal left and right
on-screen when rotated.
NOTE. The signal will not move past the minimum position setting.
