TDS3000C Series Oscilloscopes
Debug Rise Time and Fall Time Problems
Both analog and digital electronics designers
face problems related to slow edges (the rate of
change of volts over time), as measured by the
rise or fall time. The signal’s edge speed, known
as the slew rate, can affect the operation of
digital bus transceivers, transmission lines and
op-amp circuits. The TDS3000C Series’ slew
rate trigger can help troubleshoot such situations
by capturing waveforms where the slew rate is
less than, greater than, equal to, or not equal
to a specified rate. Automatic measurements
can supply supporting data.
To use the slew rate triggers:
1. In the
Trigger
section, press the
Menu
button.
2. In the bottom menu, press
Type
until
Pulse
is selected.
3. In the bottom menu, press
Class
to select
Slew Rate
.
4. Select, as desired,
Source
,
Polarity
,
Trigger When
,
Thresholds
, and
Mode & Holdoff
.
To run automatic measurements:
1. Press the front panel
Measure
button.
2. Press the
Select Measurement
bottom menu button.
3. Select the desired measurements from the side menu.
