To make cursor measurements

You can use the cursors to make custom voltage or time measurements on oscilloscope signals, and timing measurements on digital channels.

To manually control Cursors on 6000L models start the Remote Front Panel (see page 44) and select Measure from the Main Menu or press ctrl+C to access the oscilloscope’s Cursors Menu.

1 Connect a signal to the oscilloscope and obtain a stable display.

2 Press the Cursors key. View the cursor functions in the softkey menu:

Mode — Set the cursors to measure voltage and time (Normal), or display the binary or hexadecimal logic value of the displayed waveforms.

Source — selects a channel or math function for the cursor measurements.

X Y — Select either the X cursors or the Y cursors for adjustment with the Entry knob.

X1 and X2 — adjust horizontally and normally measure time.

Y1 and Y2 — adjust vertically and normally measure voltage.

X1 X2 and Y1 Y2 — move the cursors together when turning the Entry knob.

N O T E

If you intend to make cursor measurements on a trace that you recall from

memory, be sure to recall both setup and trace. See “To recall waveform

 

 

trace and/or oscilloscope setup” on page 328.

 

 

 

For more information about using the cursors, see “To make

 

cursor measurements” on page 232.
