Description 2

Queries the average value, current value, standard deviation, maximum value, or minimum value of the

negative duty cycle measurement results when the negative duty cycle measurement function of the

specified source channel and the statistic function of the measurement results are enabled.

Parameter

Range

Default

<chan>

Discrete

{CHANnel1|CHANnel2|CHANnel3|CHANnel4|MATH}

Remarks



Before making measurements, turn on the channels to be measured.



When the math operation type is FFT (refer to the :CALCulate:MODE command), <chan> cannot be

set to "MATH".



When [<chan>] is omitted, the command, by default, applies to the currently set measurement source

(refer to the :MEASure:SOURce command).

Return Format

The query returns the average value, current value, standard deviation, maximum value, or minimum value

in scientific notation. When the measurement results are invalid, the query returns 9.9e37.

:MEASure:NWIDth

Syntax 1

:MEASure:NWIDth [<chan>]

Description 1

Measures the negative pulse width of the specified source channel.

Syntax 2

:MEASure:NWIDth? [<chan>]

Description 2

Measures and queries the negative pulse width of the specified source channel. The default unit is s.
