Measuring Waveforms
TDS 500D, TDS 600B, & TDS 700D User Manual
3–135
4. TDS 600B: Press MEASURE ➞ Select Measrmnt (main) ➞ Delay
(side) ➞ Edges (main).
5. TDS 500D and TDS 700D: Press MEASURE ➞ Measure (pop-up) ➞
Select Measrmnt (main) ➞ Delay (side) ➞ Edges (main).
A side menu of delay edges and directions will appear. Choose from one of the
combinations displayed on the side menu using the following information:
The selection you choose defines which edges you want the delayed
measurement to be made between.
The upper waveform on each icon represents the from waveform and the
lower one represents the to waveform.
The direction arrows on the choices let you specify a forward search on
both waveforms or a forward search on the from waveform and a
backwards search on the to waveform. The latter choice is useful for
isolating a specific pair of edges out of a stream.
6. To take the measurement you just specified, press Delay To (main) ➞ OK
Create Measurement (side).
To exit the Measure Delay menu rather than creating a delay measurement,
press CLEAR MENU, which returns you to the Measure menu.
Sometimes you may want to see all of the automated measurements on screen at
the same time. To do so, use Snapshot. Snapshot executes all of the single
waveform measurements available on the selected waveform once and displays
the results. (The measurements are not continuously updated.) All of the
measurements listed in Table 3–11 on page 3–126 except for Delay and Phase
are displayed. (Delay and Phase are dual waveform measurements and are not
available with Snapshot.)
The readout area for a snapshot of measurements is a pop-up display that covers
about 80% of the graticule area when displayed. (See Figure 3–64.) You can
display a snapshot on any channel or ref memory, but only one snapshot can be
displayed at a time.
