To make cursor measurements

To make cursor measurements
The following steps guide you through the front-panel Cursors key. You can use
the cursors to make custom voltage or time measurements on the signal.
1 Connect a signal to the oscilloscope and obtain a stable display.
2 Press the key, then press the
Cursors
X and Y cursor information is displayed on the softkeys. ∆X, 1/∆X, ∆Y, and
binary and hexadecimal values are displayed on the line above the softkeys. The
three cursors modes are:
Normal ∆X, 1/∆X, and ∆Y values are displayed. ∆X is the difference between
the X1 and X2 cursors and ∆Y is the difference between the Y1 and Y2 cursors.
Binary
Binary logic levels are displayed directly above the softkeys for the
current X1 and X2 cursor positions for all displayed channels.
Hex Hexadecimal logic levels are displayed directly above the softkeys for the
current X1 and X2 cursor positions for all displayed channels.
In hexadecimal and binary mode, a level can display as 1 (higher than trigger
level), 0 (lower than trigger level), indeterminate state ( ), or X (don't care).
In binary mode, X is displayed if the channel is turned off. In hex mode, the
channel is interpreted as a 0 if turned off.
3 Press the softkey to select the source for your cursor
Source
measurements.
The source in Normal cursor mode can be any analog channel or math source.
If you select binary or hexadecimal mode, the Source softkey is disabled since
you are displaying binary or hexadecimal levels for all channels.
4 Select the X and Y softkeys to make a measurement.
X Y Press this softkey to select either X cursors or Y cursors for adjustment.
The cursor currently assigned to the Entry knob displays brighter than the other
cursors.
X cursors are vertical dashed lines that adjust horizontally and normally indicate
time relative to the trigger point. When used with the FFT math function as a
source, the X cursors indicate frequency.
Y cursors are horizontal dashed lines that adjust vertically and normally indicate
voltage. When math functions are used as a source, the measurement units
correspond to that math function.
