Command Descriptions

TDS3000, TDS3000B, and TDS3000C Series Programmer Manual

2- 77

CURSOR:HBARS:SELECT CURSOR1

selects the first horizontal bar cursor as the active cursor.

CURSOR:HBARS:SELECT?

returns

:CURSOR:HBARS:SELECT CURSOR1

when the first cursor is the active

cursor.

CURSor:HBArs:UNIts

Sets or queries the measurement units for the horizontal bar cursors.

Cursor

CURSor:HBArs:UNIts <QString>

CURSor:HBArs:UNIts?

<QString> is V for volts, A for amps, AA for amps

2

, A/V for amps/volts, V/A

for volts/amps, VV for volts

2

, W for watts, % for percentage, or IRE when the

IRE graticule is selected.

CURSOR:HBARS:UNITS?

returns

:CURSOR:HBARS:UNITS ”IRE”

when the horizontal bar cursor units are

IRE.

CURSor:HBArs:USE (Set Only)

Sets the horizontal bar cursor measurement scale. This command is only
applicable when ratio cursors are on.

Cursor

CURSor:HBArs:USE { CURrent | FIVEdivs }

<CURrent>

sets the H Bar measurement scale so that 0% is the current position

of the lowest H Bar cursor and 100% is the current position of the highest H Bar
cursor. Moving the cursors after executing this command does not change the 0%
or 100% scale points.
