DS2000E User’s Guide    6-31 
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.
