screen.
H Fine-adjust the generator output until the CH 1 Amplitude readout
indicates that the amplitude is 400 mV.
b. Check the AUX trigger source for stable triggering at 50 MHz: Do the
following in the order listed.
H Move the 50 Ω termination and precision 50 Ω cable from CH 1 to
AUX IN.
H Press the Trigger SOURCE button to set the source to EXT.
