Timing Acquisition Mode Field (Timing only)
The Timing Acquisition Mode field displays the acquisition type, the channel
width, and sampling speed of the present acquisition mode. The Timing
Acquisition Mode field is used to access an acquisition mode selection menu.
Conventional Acquisition Mode
In Conventional Acquisition Mode the analyzer stores measurement data at
each sampling interval.
Conventional Full Channel 250 MHz The total memory depth is
4 Kbytes with data being sampled and stored as often as 4 ns.
Conventional Half Channel 500 MHz The total memory depth is
8 Kbytes with data being sampled and stored as often as 2 ns.
Glitch Acquisition Mode
In Glitch Acquisition Mode, a glitch is defined as a pulse with a minimum
width of 3.5 ns and a maximum width of 8 ns, or the sample period,
whichever is larger. As an example, if the sample period is 8 ns, then a glitch
is defined as being between 3.5 ns and 8 ns. One advantage of the glitch
mode is that if you expand the sample rate, a pulse that is less than the
sample rate will still be displayed as a vertical dashed line.
Glitch Half Channel 125 MHz The total memory depth is split
between data storage and glitch storage. Data acquisition memory depth
is 2048 per channel. Glitch storage is 2 Kbytes per channel. Data is
sampled for new transitions every 8 ns.
