80 Digitizer Command Reference
This count specifies the portion of the total SAMPle:COUNt that will be
sampled prior to the trigger.
•
A trigger is ignored if it occurs before the pretrigger count is met.
•
If the specified number of pretrigger samples (<count>) have been taken and a
trigger has not yet occurred, the digitizer continues to sample the input signal.
The digitizer retains the most recent pretrigger samples specified by the
number "<count>" when the trigger does occur.
•
Executable when initiated: No
•
Coupled command: No
•
Reset (*RST) condition: 0 pretriggers
SAMPle:PRETrigger:COUNt? [MIN | MAX] command returns the number of
pretrigger samples each channel will make prior to each trigger. The number of
pretriggers returned is common to all channels.
SAMPle[:IMMediate] command is generally used only when the sample source is
HOLD to take a single reading when the digitizer is in the wait-for-sample state.
SAMPle:SLOPe POS | 1 | NEG | 0 command sets the slope of the sample signal
(the active edge, rising or falling, of the sample signal). The slope setting is common
to all channels.
•
This command is effective only when the sample source is EXTernal. The
slope is set but will be ignored if the sample source is a source other than
EXTernal.
•
Executable when initiated: No
•
Coupled command: No
•
Reset (*RST) condition: POSitive (1)
SAMPle:SLOPe? command queries the present setting of the slope of the sample
signal. The sample slope is effective only when the sample source is EXTernal.
