Verify the time base.
Equipment required
Prerequisites
<4 GHz models: One precision 50 Ω coaxial
cable (Item 4)
<4 GHz models: One BNC to Minigrabber
adapter (item 18)
≥4 GHz models: One SMA cable (item 21)
≥4 GHz models: One adapter (item 19)
None
1. Initialize the instrument:
Push the front-panel
Default Setup
button.
2. Hook up the signal source:
Connect the probe compensation or fast edge
output to the Ch 1 input as shown in the following figure.
Figure 4: Setup for time base test
3. Set up the instrument:
Push the front panel
Autoset
button.
4.
Set the
Vertical Scale
to
200 mV
/div (≤20 GHz models) or
120 mV
/div
(>20 GHz models).
5. Set the time base:
Set the horizontal
Scale
to
200 μs/div
. The time-base
readout is displayed at the bottom of the graticule.
6. Verify that the time base operates:
Confirm the following statements.
■
One period of the square-wave signal is about five horizontal divisions
on-screen for the 200 μs/div horizontal scale setting.
■
Rotating the horizontal
Scale
knob clockwise expands the waveform on-
screen (more horizontal divisions per waveform period),
counterclockwise rotation contracts it, and returning the horizontal scale
to 200 μs/div returns the period to about five divisions.
■
The horizontal
Position
knob positions the signal left and right on-screen
when rotated.
