2-159
Description 2
Queries the average value, current value, standard deviation, maximum value, or minimum value of the
amplitude base value measurement results when the amplitude base value measurement function of the
specified source channel and the statistic function of the measurement results are enabled. The unit is
related to the current amplitude unit of the specified source channel.

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:VMAX
Syntax 1
:MEASure:VMAX [<chan>]
Description 1
Measures the maximum amplitude value of the specified source channel.
Syntax 2
:MEASure:VMAX? [<chan>]
Description 2
Measures and queries the maximum amplitude value of the specified source channel. The unit is related to
the current amplitude unit of the specified source channel.
