attenuator_ready

Hi guys!.....finally my attenuator is ready!....i delayed i little bit because of my job.
let me correct my drawings ( of course i made some mistakes) and then i can send them who wants.
It is automatic and manual, division by 1/10/100/1000, input impedance is 100K(like all the audio analyzers in general).
Maximum signal that can arrive to the audio card input is 400 mv rms more or less, well safe....stay tuned

Hello Testman,
Could you end me information for your automatic/manual input attenuator for sound card.
Thanks,

The attenuator was designed by sankenpower. Unfortunately, I do not have a copy of it.

CA-YD-185 is an IEPE accelerometer. It requires a 24V 4mA excitation power supply as shown below. You can use an external 24V 4mA constant current power supply to drive an IEPE sensor, and feed its output to an AC coupled data acquisition system such as a sound card or a VT USB DSO. You can also use our product VT IEPE-2G05 which already has built-in 24V 4mA power supplies to excite the IEPE sensors.
