Acquiring and Displaying Waveforms
TDS 500D, TDS 600B, & TDS 700D User Manual

3. Press Horiz Pos (main), then Frame (side), and use the general purpose
knob to enter the number of a specific frame to view. After you press Enter,
that frame should appear on the display.
If you shift the waveform right or left with the front-panel HORIZONTAL
POSITION knob, the window next to the side-menu Frame button will indicate
the frame number of the waveform at the center of the screen.
Use TimeStamp to display the absolute trigger time for a specific frame and the
relative time between triggers of two specified frames. To start FastFrame
TimeStamp, do the following steps:
1. Turn on FastFrame as described starting on page 3–68.
2. To select the Reference Frame, press HORIZONTAL ➞ FastFrame
Setup (main) ➞ Reference Frame (side). Then use the general purpose
knob or the keypad to select the reference frame. This value sets the starting
frame when measuring the relative time between two frames.
3. To select the Position Frame, press HORIZONTAL ➞ FastFrame
Setup (main) ➞ Position Frame (side). Then use the general purpose knob
or the keypad to select the position frame. This value sets the ending frame
when measuring the relative time between two frames.
4. To lock the reference and position frames together, press HORIZONTAL ➞
FastFrame Setup (main). Then toggle Lock Frames (side) to ON. If ON,
they maintain the same relative distance from each other when either frame
is adjusted.
5. To turn TimeStamp on, press HORIZONTAL ➞ FastFrame Setup (main).
Then toggle TimeStamp (side) to ON (see Figure 3–35).
The displayed time uses the following format:
@Pos: xxx Position (or reference) frame number
DD MMM YYYY Date (day, month, and year)
HH:MM:SS.mmm, Clock time (hours, minutes, seconds, and milliseconds)
mmm,nnn,ppp Fraction of a second (to picoseconds)
