Signal Flow of the DL850E/DL850EV
The input terminal signal flow varies for each model. In this example, we will explain the signal flow
for the High-Speed 10 MS/s, 12-Bit Isolation Module, 701250 (HS10 M12). (For the signal flow of a
particular module, see the module’s block diagram.)
The input signal applied to the two input terminals is first processed by each module’s input section.
In the 701250 (HS10 M12), the signal is attenuated and amplified by an attenuator (ATT) and
amplifier (AMP). Then, the signal’s bandwidth is limited by a filter (FLT). Next, the signal is sampled
at a rate of 10 MS/s (10,000,000 times a second) by an A/D converter and converted into digital
data. Then, the signal passes through an isolator and an ASIC to a waveform-processing ASIC
(ACQ-ASIC).
The 16 channel of digital data that is sent to the CPU board passes through the GIGAZoom Engine2
waveform processor and is stored to the acquisition memory (ACQ Memory). The digital data stored
to the ACQ memory is compressed quickly by the GIGAZoom Engine2, and then it passes through
a graphic controller and is shown on the XGA TFT color display.
The realtime math feature (/G3 option) uses the A/D converted data of the analog input channels
or the math results of realtime math channels or both as its math sources and performs math
operations on the specified channels in real time.
You can use the DL850E/DL850EV to perform realtime math on up to 16 channels at the same
time.
