Note: The display mode of the measurement results displayed at the upper left
corner of the screen will be different in different cursor display mode, measurement
source and units currently selected. When the vertical unit is set to "Source Unit":
In X (or Y) display mode, A->Y, B->Y and △Y (or A->X, B->X, △X and 1/△X) will
not be displayed.
When the measurement source is MATH (FFT), the units of A->Y and B->Y are
"dBV" and the unit of △Y is "dB".
When different horizontal unit is selected, the unit of A->X, B->X, △X and 1/△X
is different (for the details, please refer to the introduction below). When the
horizontal unit is set to "°" or "%", 1/△X will not be displayed.
1. Select Display Mode
Press DisplayMode to select "X", "Y" or "X-Y".
The X cursors are a pair of vertical solid/dotted lines and are usually used to
measure time parameters.
The Y cursors are a pair of horizontal solid/dotted lines and are usually used
to measure voltage parameters.
The X-Y cursors are a pair of vertical solid/dotted lines and a pair of
horizontal solid/dotted lines and are usually used to measure time and
voltage parameters at the same time.
2. Select Measurement Source
Press Source to select the waveform of the analog channels (CH1 or CH2) or
math operation results (MATH) for measurement. If "None" is selected, no
cursor will be displayed.
Note: For CH1, CH2, and MATH, only the currently enabled channel can be
selected.
3. Select Screen Region
When Zoom is enabled (pressing the HORIZONTAL
SCALE can
enables Zoom), the screen is divided into two regions, Main and Zoom.
Press Screen to select "Main" or "Zoom". When "Main" is selected, the
cursors are displayed in the main region and measure the signal displayed
in the main region. The measurement results are displayed in the zoom
region. When "Zoom" is selected, the cursors are displayed in the zoom
region and measure the signal displayed in the zoom region. The
measurement results are displayed in the main region.
