Description
A-10 TDS1000B and TDS2000B Series Oscilloscopes – Operator Training Kit
VARIABLE AMPL WITH GLITCH
Analog signal
Frequency: 10 Hz
Amplitude: Variable between 1 V and 4 V,
following sine wave at 0.1 Hz rate
20 ns asynchronous glitch, 5 V amplitude, at 1 Hz
rate
This signal is a 10 Hz square wave with an
amplitude that follows a 0.1 Hz sine wave. In
addition, a +5 V DC 20 ns pulse combines with
the signal at an asynchronous 1 Hz rate. The
glitch is visible on an oscilloscope if the sweep
speed is increased and set to trigger on a narrow
pulse. This signal can be used to demonstrate
how to capture and analyze infrequent high-
speed glitches with the use of the Peak Detect
acquisition mode on a TDS1000B or a TDS2000B
oscilloscope.
