:MEASure:ADISplay
Syntax
:MEASure:ADISplay <bool>
:MEASure:ADISplay?
Description
Enables or disables the all measurement function; or queries the on/off status of the all measurement
function.

{{1|ON}|{0|OFF}}
0|OFF
Remarks
The all measurement function can measure all the time, voltage, and area parameters of the specified
channel(s) and display the measurement results on the screen. The specified channel(s) refer to one
or multiple channels among CH1-CH4 and MATH. Each measurement source has 21 waveform
parameters, as shown below.
8 time parameters: period, frequency, rise time, fall time, positive pulse width, negative pulse width,
positive duty cycle, and negative duty cycle.
11 voltage parameters: maximum, minimum, peak-peak, top, base, amplitude, average, Vrms, Per.
Vrms, overshoot, and preshoot.
2 area parameters: area and period area.
Vrms: indicates the root mean square value of the voltage values of the waveform points (relative to
the ground). The operation formula is as follows:
n

Wherein,
i
x
is the measurement result of the ith point being measured;
n
is the number
of points being measured.
Per. Vrms: indicates the root mean square value of the voltage values of the waveform points (relative
to the ground) within a single period. The operation formula is as shown above.
Area: The horizontal axis denotes time and the vertical axis denotes waveform amplitude. The
oscilloscope calculates the area (namely the integral of the time and amplitude) of the waveform. The
default unit is volt-second.
Period area: The horizontal axis denotes time and the vertical axis denotes waveform amplitude. The
oscilloscope calculates the area (namely the integral of the time and amplitude) of a single period of
waveform. The default unit is volt-second.
Note: If the waveform within the current measurement range is less than a period, the measurement
results of "Per. Vrms" and "Period area" are displayed as *****.
Return Format
The query returns 1 or 0.
:MEASure:AMSource
Syntax
:MEASure:AMSource <chan>[,<chan>][,<chan>][,<chan>][,<chan>]
:MEASure:AMSource?
Description
Sets or queries the source channel(s) of the all measurement function.
