Note˖Ɣ The oscilloscope vertical response rolls off slowly above its bandwidth ,

which depending on the model, or 20 MHz when the Bandwidth Limit

option is set to “On”. Therefore, the FFT spectrum can show valid

frequency information higher than the oscilloscope bandwidth. However,

the magnitude information near or above the bandwidth will not be

accurate.

Ɣ If the channel is set to DC couplingˈyou can quickly measure the DC

component of the signal by simply nothing its distance from the ground

symbol.

Ɣ If the channel is set to AC couplingˈthe DC component of the signal is

blocked allowing you to use greater sensitivity to display the AC

component of the signal.

Setting up the CH1ǃCH2 Channels

Each channel has its own separate Menu. The items are set up separately

according to each channel.

1. Set up the channel couple

Take the CH1 for example; the tested signal is a sine wave signal with DC

deflection:

Ɣ Press“CH1”ĺ“Coupling”ĺ“AC”, Set to AC couple mode. It blocks the DC

component of the input signal.
