The block diagram in Figure 2-1 illustrates the key functional units of the
NI 1410.
Figure 2-1. NI 1410 Block Diagram
Video Multiplexer
The video multiplexer routes one of the four AC-coupled video inputs to
the 10-bit ADC circuitry. The input impedance is 75 Ω.
Programmable Gain and Offset
The NI 1410 uses programmable gain and offset circuitry to optimize the
input signal range.
Analog Bandwidth Control Circuitry
You can select either the full bandwidth of 30 MHz or a reduced bandwidth
of 9 MHz. The 9 MHz bandwidth setting is available using a 5th order
Butterworth lowpass filter.
10-Bit ADC
The 10-bit ADC digitizes the conditioned video signal.
