Some design problems you can anticipate…others, you
can’t. If you don’t know what you are looking for, advanced
triggering capability will not get you very far. This is where
waveform update rate becomes critical. The higher the
waveform update rate, the greater the probability of
capturing intermittent signal glitches and anomalies.
Let’s see the impact of waveform update rate when it
comes to acquiring and viewing an intermittent glitch
that occurs in the signal, on average, only once every
40,000 cycles.
Lab 2
Discovering an infrequent
glitch with fast waveform
update rates
Your demo kit should come with a USB cable.
Connect the ‘A’ receptacle of the cable to a USB
host port on the back panel of the 5000 Series.
Connect the ‘B’ receptacle of the cable to the
demo board. The USB connection provides
power to the demo board.
Connect the channel 1 probe to the test points
labeled CH1 and ground (GND).
Set the demo board’s MODE dial to 1 to activate
the GLITCH signal.
