TDS 500B and TDS 700A Models Only: In FastFrame mode, the @ shows the
time position of the selected cursor relative to the trigger point of the frame that
the selected cursor is in. The D shows the time difference between the two
cursors only if both cursors are in the same frame.
Paired. The value after one D shows the voltage difference between the two Xs;
the other D
shows the time (or frequency) difference between the two long
vertical bars. The value after @ shows the voltage at the X of the selected cursor
relative to ground. (See Figure 3–61.)
TDS 500B and TDS 700A Models Only: In FastFrame mode, the D shows the

Paired cursors can only show voltage differences when they remain on screen. If
the paired cursors are moved off screen horizontally, the word Edge will replace
the voltage values in the cursor readout.
This procedure and those that follow detail the process for taking a cursor
measurement. To select the type of cursors you want, do the following steps:
1. To display the cursor menu, press CURSOR. (See Figure 3–60.)
