get(channel=Channel.Default) → Coupling[source]
# CHANnel<*>:COUPling
value: enums.Coupling = driver.channel.coupling.get(channel = repcap.Channel.Default)

Sets the connection of the channel signal, i.e. the input impedance (termination) and a filter (coupling) . The command determines what part of the signal is used for waveform analysis and triggering.

Parameters:

channel – optional repeated capability selector. Default value: Ch1 (settable in the interface ‘Channel’)

Returns:

user_coupling: DC | DCLimit | AC

  • DC: Connection with 50 Ω termination, passes both DC and AC components of the signal.

  • DCLimit: Connection with 1 MΩ termination, passes both DC and AC components of the signal.

  • AC: Connection with 1 MΩ termination through DC capacitor, removes DC and very low-frequency components. The waveform is centered on zero volts.

set(user_coupling: Coupling, channel=Channel.Default) → None[source]
# CHANnel<*>:COUPling
driver.channel.coupling.set(user_coupling = enums.Coupling.AC, channel = repcap.Channel.Default)

Sets the connection of the channel signal, i.e. the input impedance (termination) and a filter (coupling) . The command determines what part of the signal is used for waveform analysis and triggering.

Parameters:

  • user_coupling –

    DC | DCLimit | AC

    • DC: Connection with 50 Ω termination, passes both DC and AC components of the signal.

    • DCLimit: Connection with 1 MΩ termination, passes both DC and AC components of the signal.

    • AC: Connection with 1 MΩ termination through DC capacitor, removes DC and very low-frequency components. The waveform is centered on zero volts.

  • channel – optional repeated capability selector. Default value: Ch1 (settable in the interface ‘Channel’)
