Attribute Summary:
Description:
When you change the height of the vertical division of the trace (DISP:TRAC:Y:PDIV) the specified
Y-axis reference position remains constant or fixed. The specified trace moves up or down in the display
area when you change the reference position.
The trace specifier, WINDow [1|2|3|4], determines which trace you are selecting. Omit the specifier or
send WIND1 for trace A, WIND2 for B, WIND3 for C, or WIND4 for D.
To fix the top of the specified display as the Y-axis reference point, send DISP:TRAC:Y:REF TOP.
To fix the center of the specified display as the Y-axis reference point, send DISP:TRAC:Y:REF
CENT.
To fix the bottom of the specified display as the Y-axis reference point, send DISP:TRAC:Y:REF
BOTT.
To specify a value for the reference point, send the DISP:WIND:TRACE:Y:TOP,
DISP:WIND:TRACE:Y:CENT, or DISP:WIND:TRACE:Y:BOTT command.
To select Y-axis scaling which is based on the input range of the channel supplying measurement data,
send DISP:TRAC:Y:REF RANG. This is called automatic reference level tracking.
