SCOPE mode provides a display of signal patterns from either CH A or CH B over times
ranging from 10ns to 2Hours per division, and for voltage ranges from 10mV to 500 V full
scale.
Using Single and Dual Input Scope Mode The instrument can be configured to show scope
displays for either CH A or CH B signals: In DUAL INPUT SCOPE mode, both CH A and CH
B may be displayed at the same time.
Use SINGLE INPUT SCOPE mode if you want to measure a single signal, INPUT B is turned
off.
Use DUAL INPUT SCOPE mode if you want to simultaneously measure two signals.
