Note: The A/D Clock Source signal may also be output to the terminal connector/panel, to do this you must
modify the adac-tp.ini file using the ADAC Config program and set the ClockOutput setting to ENABLED.
5.4.1 Internal Clocking
For non-burst acquisition, TestPoint’s A/D Objects “StartA/D”, “AcquireA/D” or “StartD/A” rate
parameter is used to program the on-board pacer clock to the rate at which the A/D conversions are
clocked.
For the A/D the rate is a multiple of the number of channels specified in the Channel(s)= parameter, i.e. if
the rate were equal to 1000 and the Channel(s) = 0, 1, 2, 3, 4, 5, 6, 7, the actual A/D clocking would be
8000 Hz, 1000 Hz. per channel.
5.4.2 External Clocking
In non-Burst mode acquisition, the (ADCLKIN) or (DACLKIN) input can be used to clock the A/D
conversions. To select the external clocking mode, set the TestPoint A/D Objects “StartA/D”,
“AcquireA/D” or “StartD/A” rate parameter to 0.
