Timebase
Setup
TIMEBASE Press
to access and choose:
Ø Single-Shot or Interleaved (RIS) sampling
Ø External clock
Ø Channel pairing (combining) and Peak Detect ..
Ø Sequence Mode
Ø Number of segments in Sequence Mode
Ø Maximum record length.
The “TIMEBASE” menus also show the number of points acquired,
the sampling rate and the total time span.
Sampling
For selecting either of the two principal modes of acquisition:
Ø “Single Shot” — displays data collected during successive
single-shot acquisitions from the input channels. This mode
allows the capture of non-recurring or very low repetition-rate
events simultaneously on all input channels.
Ø “RIS” (Random Interleaved Sampling) — achieves a higher
effective sampling rate than Single-Shot, provided the input
signal is repetitive and the trigger stable.
Sample Clock
To select “Internal” or External (“ECL”, “OV”, “TTL”) clock modes
(see next page).
Channel Use (NOT AVAILABLE WITH 9304C, 9310C, 9314C
SERIES)
To select for channel pairing and, on models with this feature, to
control Peak Detect Mode (refer page 7–2).
Sequence
For turning “Off” or selecting “Sequence” or “Wrap” Mode. See
page 7–10.
