Keep your equipment and software up to date, and troubleshoot any technical issues that may arise to ensure The FRA Software is compatible with all our FRA's that have a GPIB control interface, and allows transfer function measurements to be made. For this note it is assumed that the output of the pulse gen is in channel A and the return signal from the microphone in channel B. The principle of the app is quite simple. Study the noise characteristics of acoustic environments or electronic gear. cypress. MTF is the spatial frequency characteristic that expresses how faithfully the contrast of the subject for the imaging target can be reproduced The Room Acoustics Reporter is a PC software for automatically generating reverberation time measurement reports and analyzing the frequency response spectrum. When I use the jig, in the x1/10 option, I do not know what I am measuring. • Gain from x1 to x1000 • Trigger on A five percent reduction in frequency yields a five percent reduction in motor speed. That is, the frequency you are measuring cannot exceed the maximum input frequency supported by the counter, even though it may exceed that of the internal timebase.
