Horizontal and acquisition setups Select a s ampling mode
The sampli
ng speeds and the number of channels you choose affect the mode the instrument uses to
sample waveforms. The instrument always uses real-time sampling at slower time base settings; faster
time settings force the instrument to switch from real-time sampling to equivalent-time sampling.
The following tables show the time base setting(s) at which the switch from real-time sampling (RT) to
equivalent-time sampling (ET) occurs for your instrument.
