:SOUR1:FUNC:RS232:DATAB? /*Queries the RS232 data bit of CH1 and the query returns 7.*/
[:SOURce[<n>]]:FUNCtion:RS232:STOPBit
Syntax
[:SOURce[<n>]]:FUNCtion:RS232:STOPBit {1|1.5|2}
[:SOURce[<n>]]:FUNCtion:RS232:STOPBit?
Description
Sets the RS232 stop bits of the specified channel.
Queries the RS232 stop bits of the specified channel.

Remarks
When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
Return Format
The query returns 1, 1.5, or 2.
Example
:SOUR1:FUNC:RS232:STOPB 2 /*Sets the RS232 stop bit of CH1 to 2.*/
:SOUR1:FUNC:RS232:STOPB? /*Queries the RS232 stop bit of CH1 and the query returns 2.*/
[:SOURce[<n>]]:FUNCtion:SEQuence:EDGETime
Syntax
[:SOURce[<n>]]:FUNCtion:SEQuence:EDGETime <seconds>
[:SOURce[<n>]]:FUNCtion:SEQuence:EDGETime?
Description
Sets the edge time of the sequence waveform of the specified channel.
Queries the edge time of the sequence waveform of the specified channel.

7 ns
Remarks
 When [:SOURce[<n>]] or [<n>] is omitted, the system sets the related parameters of CH1 by default.
 This command is only valid when the sequence filter is in interpolation mode.
Return Format
The query returns the edge time of the sequence waveform in scientific notation, with 7 effective digits. For
example, 5.000000E-07 (the edge time is 0.5 μs).
Example
:SOUR1:FUNC:SEQ:EDGET 0.0000005 /*Sets the edge time of the sequence waveform of CH1 to 0.5 μs.*/
:SOUR1:FUNC:SEQ:EDGET? /*Queries the edge time of the sequence waveform of CH1 and the
query returns 5.000000E-07.*/
