RIGOL Chapter 6 MATH and Measurements
6-26 MSO2000A/DS2000A User’s Guide
A-> Y: the Y value at cursor A. Y value takes the channel GND of CH1 as
reference. Its unit is the same as that of the current signal source.
B-> X: the X value at cursor B. X value takes the trigger position as reference. I ts
unit is “s” or “Hz” (when measuring FFT waveform).
B-> Y: the Y value at cursor B. Y value takes the channel GND of CH1 as
reference. Its unit is the same as that of the current signal source.
△X: the horizontal difference between cursor A and B.
1/ △X: the reciprocal of the horizontal difference between cursor A and B.
△Y: t he vertical difference between cursor A and B.
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”.
The units of A-> X, B-> X, △X and 1/△X will vary with different horizontal unit
currently selected.
When the measurement source is set to LA, the display mode will be set to X
automatically and the measurement results will be displayed in the following form.
CurA: the X value at cursor A. X value takes the trigger position as reference.
D15D0: display the logic level values at cursor A (D15-D0 from left to right) in
hexadecimal and binary forms. If the digital channel is currently turned off, it will
be denoted by X in the binary data.
CurB: the X value at cursor B. X value takes the trigger position as reference.
D15D0: display the logic level values at cursor B (D15-D0 from left to right) in
hexadecimal and binary forms. If the digital channel is currently turned off, it will
be denoted by X in the binary data.
