With LINK readout/profile trigger set to ON, switching to Readout
mode uses the same trigger conditions, but allows the full dynamic
range of the meter to be used, as well as providing full GPIB speed
on data acquisition.
When moving between Readout and Profile modes, with LINK en
-
abled, the value used for “sample delay” is modified using the
“display trigger delay.” In Readout mode, the “sample delay” and
“display trigger delay” values are combined as “sample delay,”
whereas in Profile mode they are both available separately.
FAST
Fast recall of a saved instrument setup from one of the 10 memory
locations. In FAST system recall mode, a single key press recalls a
saved setup. A message across the lower area of the screen will
prompt for keypad keys 1-9, or 0, to be pressed to recall setups
1-10 (if saved setup data is available in the selected location). The
-exit- softkey or any other menu key will exit fast recall mode.
PRESET
Resets the system parameters to the default setup (see Appendix
A, Section A-3).
RESET
[*RST]
This selection will reset the system setup. The offset tables and the
GPIB interface will not be affected.
FACTORY
[FRST]
This selection will reset the system setup, including the offset ta-
bles and GPIB interface.
Profile This soft key becomes available when the System|Setup|MODE is set to Profile.
Profile operation mode includes the following display controls:
CHANNEL
[GRMD]
Select Channel 1 or Channel 2. The channel selected will be dis
-
played on the left of the screen, above the middle value of the y
axis and is used for all Profile data displays.
PERIOD
[GRPRD]
Sets the time period over which the system collects data and
scales the data into the profile graph after a trigger event. Enter the
data collection period in ms or µs. See System|Graphics|Pretrig %
to move the t=0 (trigger event position) of the displayed waveform.
DELAY
[DTRGD]
Specifies the period of time after a trigger event to delay the start of
the display window. For the trigger to line up with the marked trigger
point on repetitive waveforms, the delay period should be either
zero, or set to integer multiples of 1/PRF (Pulse Repetition Fre
-
quency). Enter the delay period in ms or µs.
