■
Leave the trigger system triggered on the positive slope of the
waveform before proceeding to the next check.
■
Press the Trigger Source button to toggle it to Ch 1.
4. Confirm that the A trigger system is within sensitivity limits (full bandwidth):
a. Set the Horizontal Scale: Set the Horizontal Scale to 200 ps.
b. Display the test signal:
■
Set the generator frequency to full bandwidth as follows:
Model Generator frequency
≥ 4 GHz models 4 GHz
DPO7354C 3.5 GHz
DPO7254C 2.5 GHz
DPO7104C 1 GHz
DPO7054C 500 MHz
■
Set the generator amplitude on screen as follows:
Model Amplitude
≥ 4 GHz models 2 divisions
DPO7354C 2.5 divisions
DPO7254C 6 divisions
DPO7104C 6 divisions
DPO7054C 6 divisions
■
Now fine adjust the generator output until the Ch 1 Amplitude
readout indicates the amplitude is as follows (readout may fluctuate):
Model Amplitude
≥ 4 GHz models 200 mV
DPO7354C 250 mV
DPO7254C 600 mV
DPO7104C 600 mV
DPO7054C 600 mV
■
Disconnect the cable at Ch 1 and reconnect it to Ch 1 through an
attenuator:
