while the minimum should be 1 MHz. Refer to section 4.6 for
information on user-controllable timing signals.
Figure 4-3: Scan Timing
There are four trigger modes to start the scan acquisition. Refer to
section 4.1 for details. The data transfer mode is discussed in the
following section.
NOTES The maximum A/D sampling rate is 2 MHz for DAQ/
DAQe/PXI-2010, 500 kHz for DAQ/DAQe/PXI-2005, 250
kHz for DAQ/DAQe/PXI-2006 and 800 kHz for DAQ/
DAQe/PXI-2016. Therefore, the minimum setting of
SI_counter is 20 for DAQ/DAQe/PXI-2010, 80 for DAQ/
DAQe/PXI-2005, 160 for DAQ/DAQe/PXI-2006 and 50
for DAQ/DAQe/PXI-2016 while using the internal TIME-
BASE.
The SI_counter is a 24-bit counter. Therefore, the maxi-
mum scan interval while using an internal TIMEBASE =
224/40 Ms = 0.419 s.
