the measurement source by switching the current active channel
(press CH1 to CH4 at the front panel).
― For the digital channels (D0 to D15), the “One-key measurement”
function only supports period, frequency, +Width, -Width, +Duty Cycle
and –Duty Cycle measurements.
― When the math operation type is set to “FFT”, the measurement source
cannot be set to “MATH”.
Delay and phase parameter measurements
Press Measure Setting Type, turn the multi-function knob to
select “Delay” or “Phase” and press the knob. You can also press Type
continuously to switch the current measurement type. Then, press
SourceA and SourceB to set the two source channels (CH1 to CH4 or D0
to D15) of the current measurement type respectively.
Note: When SourceA is set to an analog channel (or digital channel),
SourceB can only be set to an analog channel (or digital channel).
2. Perform auto measurement
1) Press MENU at the left of the screen continuously to open the desired
waveform parameter measurement menu.
2) Use the page up/down key / at the left of the screen to select the
specified menu page (namely the menu page that contains the parameter
to be measured).
3) Press the corresponding menu softkey to measure the corresponding
parameter of the current measurement source. The measurement result
will be displayed at the bottom of the screen.
The menu item icons and measurement results of time, voltage and area
parameters are always in the same color as the current measurement channel.
The menu item icons and measurement results of delay and phase parameters
are always in white; the numbers in the menu item icons and results denote
source A and source B currently selected (when the signal source is an analog
channel, the color of the number is the same as that of the channel selected;
when the source channel is a digital channel, the number is always in green).
Note: If the measurement result is displayed as “*****”, there is no signal input
