I have a single SCXI-1102B module in a SCXI-1000 chassis. It is used for precise temperature measurements, where in particular the noise in the range 0.01 to 10Hz is required to be as low as possible. Unfortunately, by some bureaucratic error, I got only one set of filler panels. There is no time to get the rest.
One easy way out is to cover the openings with blind panels cut to the size. This would probably strengthen the air flow through the one module.
Another way out is to cut one blind panel to cover the front opening and one perforated panel to cover the back opening, so as to maintain the ventilation through the single module to a level such as in the case of four modules being present.
However, it seems to me that the holes in the back of the modules are smaller not larger than the holes in the filler panel, so a filler panel would not equivalate the aerodynamic resistance of the holes in the back of a module + the inside circuit in the module.
So maybe the distribution of the flow of air between the modules and the un-occupied slots is not that important ?
The question is:
Is this matter of importance to the very low frequency noise level ? Or is this problem of a much lesser order of magnitude by it's influence and needs not to be addressed ?
