Signal Flow on the SL1400
The flow of the signal applied to the input signal varies depending on the input module. Here, the high-speed 10
MS/s, 12-bit isolation module (701250 (HS10M12)) is used as an example for the explanation. (For details on the
flow of the signal of each module, see the block diagram.)
The signal applied to the two input terminals is first processed by the input section of each module.
On the 701250 (HS10M12), (1) the attenuator (ATT) attenuates and the amplifier (AMP) amplifies the input signal,
(2) the filter (FLT) limits its bandwidth, and (3) the A/D converter samples the input signal at a sample rate of 10
MS/s (10 million times per second) and converts the signal to digital data. Then, the signal passes through the
isolator and ASIC and enters the waveform processing ASIC (ACQ-ASIC).
The 16 channels of digital data collected at the CPU board passes through the waveform processing ASIC (ACQ-
ASIC) and stored in the acquisition memory (ACQ Memory). The digital data stored in the ACQ memory is
compressed at high speeds by the waveform processing ASIC (ACQ-ASIC), passes through the graphic controller,
and shown on the SVGA TFT color display.
The SL1400 can acquire simultaneously up to 16 analog input channels and 16-bit logic data.
