[I am relaying information from Vijay here, my free interpretation]

An S series board should be used as the primary board. The board tested and benchmarked in the article (2003) is NI PCI-6110, a 12-Bit, 5 MS/s/channel DAQ board. This is a PCI-card and supports the rates need for input digitiazation (1.25MHz).

ScanImage 3.7 can also use X series cards (e.g. PCIe-6321 or 6323) with DAQmx 9.2.2. (http://www.ni.com/xseries/). These PCIexpress cards can be used as the optional second board for Pockels cell control and/or to have full frame/line/pixel clock features.

• PCI-6110 http://sine.ni.com/nips/cds/view/p/lang/en/nid/11888- the recommended S series PCI card

• PCIe-6321 http://sine.ni.com/nips/cds/view/p/lang/en/nid/207405 - an X series 250 kS/s aggregate 16-bit board
  

possible faster and more expensive alternative for the main card?

• PCI-6115 http://sine.ni.com/nips/cds/view/p/lang/en/nid/11886 - an S series PCI card  10 MS/s/channel board with onboard anti-aliasing filters

Is PCIe-6361 the card that can do it all?

• 16 analog inputs, 2 MS/s 1-channel, 1 MS/s multichannel; 16-bit resolution, ±10 V
• Two analog outputs, 2.86 MS/s, 16-bit resolution, ±10 V
• 24 digital I/O lines (8 hardware-timed up to 10 MHz)
• Four 32-bit counter/timers for PWM, encoder, frequency, event counting, and more
• Analog and digital triggering and advanced timing with NI-STC3 technology
• Support for Windows 7/Vista/XP/2000

According to http://sine.ni.com/ds/app/doc/p/id/ds-151/lang/en, this card could output 2 channels at 2MS/s each and sample a single channel at 2MS/s, and multichannel at aggregate 1MS/s.
