There are three horizontal display modes: main only, main intensified, and
delayed only. You can select among various horizontal record length settings.
A feature called “Fit to Screen” allows the user to view entire waveform
records within the 10 division screen area. In other words, waveforms are
compressed to fit on the screen. The exception is that, with Option 1M,
50,000 point records are displayed over a 15 division time span. (see
Table 2-1)

1 The 50,000 samples in 1,000 division record is only available with Option 1M.
2 The maximum record length of 15,000 samples (50,000 samples with Option 1M) is select-
able with all acquisition modes except Hi Res. In Hi Res, the maximum record length is
5,000 samples (15,000 samples with Option 1M).
FastFrame
TM
allows multiple triggered acquisitions to occur with a minimum
of “dead time” between acquisitions. A maximum of 910 acquisition se-
quences (frames) are possible with 50 points per record (frame length) when
a 50,000 point waveform record length is available (with option 1M).
You can delay by time with respect to the main trigger both the delayed
display and the intensified zone on the main intensified display. You can set
them to display immediately after the delay (delayed runs after main mode).
The delayed display can also be set to display at the first valid trigger after
the delay (delayed triggerable mode).
You can also delay by a selected number of events the delayed display (or
the intensified zone). In this case, the events source is the delayed trigger
source. For any events signal, the delayed-trigger system conditions the
signal by determining the source, coupling, etc., of that signal.
