Debug Rise Time And Fall Time Problems - Tektronix TDS3000C Series Manual

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.
