CSA8000B & TDS8000B User Manual
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.
H Rotating 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
1 s/div returns the period to about five divisions. Leave the time base
set to 1 s/div.
H The horizontal POSITION knob positions the signal left and right
on-screen when rotated.
NOTE. The signal will not move past the minimum position setting.
