Bandwidth Limit Indicators:
The T3DSO2000A has two available bandwidth limits: 20 and 200 MHz. They are indicated
by the following icons:
：20 MHz bandwidth limit
：200 MHz bandwidth limit
：On the 500 MHz model, anti-aliasing filter is automatically turned on when the channel is
in non-interleaving mode (i.e. sample rate ≤ 1 GSa/s). The bandwidth of the anti-aliasing
filter is around 350 MHz.
None: Full bandwidth
Invert Indicator--shows that the current channel is inverted:
： Invert has been turned on
None: Invert has been turned off
Coupling and Input Impedance:
：DC coupling, 1 MΩ impedance
：DC coupling, 50 Ω impedance
：AC coupling, 1 MΩ impedance
：AC coupling, 50 Ω impedance
：Ground
