Using the Oscilloscope 3
Keysight U1610/20A User’s Guide 55
Edge trigger
The Edge trigger identifies a trigger by looking for a specified edge (slope) and
voltage level on a waveform.
Source
Press repeatedly to select the trigger source.
Coupling
Press repeatedly to select either:
– DC coupling – allows DC and AC signals into the trigger path.
– AC coupling – removes any DC offset voltage from the trigger waveform.
– LF (low frequency) reject coupling – removes any unwanted low-frequency
components from the trigger waveform.
– HF (high frequency) reject coupling – removes high-frequency components
from the trigger waveform.
Slope
Press repeatedly to select the Rising ( ) edge, Falling ( ) edge,
Alternate ( ) edges, or Either ( ) edge.
All modes operate up to the oscilloscope bandwidth except the Either edge mode,
which has a limitation. The Either edge mode will trigger on constant wave signals
up to 100 MHz, but can trigger on isolated pulses down to 1/(2 × oscilloscope
bandwidth).
Level
Press and use the or key to set the trigger level.
