3.6 Unit
Sets the amplitude display unit for the selected channel. The available units are
V
(voltage) and
A
(current). When the unit is changed, the unit displayed in the channel information bar will change
accordingly.
To change the unit:
1. Press the
CH1
button.
2. Press the
F5
soft key to enter the second page of the CH1 function menu.
3. Press the
F1
soft key to toggle between
V
and
A
.
The default setup is
V
.
3.7 Deskew
When measuring time intervals in the nanoseconds (ns) range, small differences in cable length can
affect the measurement. Use Deskew to remove cable-delay errors between any two channels.
For example, two coaxial cables with a 1-inch difference in length could introduce a skew of more than
100 ps. In some scenarios (e.g. measuring the setup/hold time between clock and data), it may be
necessary to compensate the skew between channels.
The method of compensation: Probe the same signal simultaneously using two channels (including the
cables or probes that you intend to use for measurements) and adjust the deskew parameter of one
channel until the waveforms of the two channels observed on the screen coincide horizontal
To set
Deskew
:
1. Press the
button.
2. Press the
F5

3. Press the
F2
soft key.
4. Use the
to set the deskew value.
• Pressing enter button will call the numeric keypad.
