2-10 TDS5000B Series Specifications and PerformanceVerification
HRotating the horizontal SCALE knob clockwise expands the waveform
on-screen(more horizontal divisions per waveform period), counter-
clockwise rotationcontracts it, and returning the horizontal scale to
200 s/div returns theperiod to about five divisions.
HThe horizontalP OSITIONknob positions the signal left and right
on-screen when rotated.
6. Verifyhorizontal delay:
a. Center a rising edge on screen:
HSet the horizontalP OSITIONknob so the rising edge, where the
waveformis triggered, lines up with the center horizontal graticule.
HChange the horizontalS CALE to 20 s/div.The rising edge of the
waveformshould remain near the center graticule and the falling
edge should be offscreen.
b. Turnon and set horizontal delay:
HPull down the Horiz/Acq menu to select Horizontal/Acquisition
Setup.. . .
HClick the Horizontal tab in the control window that displays.
HClick the Delay Mode button to turn delay on.
HDouble click the Horiz Delay control in the control window to
display the pop-up keypad.C lickthe keypad buttons to set the
horizontal delayto 500 s, and then click the ENTER key.
c. Verifythe waveform: Verify that a fallingedge of the waveform is within
a few divisions of center screen.
d. Adjust the horizontal delay:Rotate the upper multipurpose knob to
change the horizontaldelay setting. Verify that the falling edge shifts
horizontally.Rotate the front-panel horizontal POSITION knob. Verify
that this knob has the sameeffect (it also adjusts delay, but only when
delay mode is on).
e. Verifythe delay toggle function:
HRotate the front-panelhorizontal POSITION knob to center the
falling edgehorizontally on the screen.
HChange the horizontalS CALE to 40 ns/div (50 ns/div for
TDS5054BE). The falling edge of the waveform should remainnear
the centergraticule. If not, readjust the delay setting to center the
falling edge.
