Command 3 - SAMPLE AND TRIGGER SETUP

Command 3 specifies sampling duration, when to start sampling (trigger),
and whether or not to record time data. Executing Command 3 clears any
data currently in data analyzer memory, and puts the data analyzer into the
READY state.
Syntax
{3, Sample Time, Number of Samples, Record Time, Trigger Source, Trig-
ger Threshold, Trigger Edge, Clock Source, Clock Threshold, Clock Edge,
Prestore Data%, Filter}
• Make sure that Command 3 always is the last command sent to the data
analyzer before sampling starts.
• When controlling the data analyzer with a CFX-9850G, be sure to al-
ways insert a display halt command (^) following the Send( command.
This tells the CFX-9850G to pause until sampling by the data analyzer is
finished, and ensures smooth data communications. Once sampling is
finished, pressing [EXE] on the data analyzer restarts the program. If the
CFX-9850G is left for more than 60 minutes without performing any key
operation, its Auto Power Off function will activate, turning off CFX-9850G
power.
