Turbon Posted April 2, 2016 Report Share Posted April 2, 2016 Hi. Got myself interested in measurements so I am slowly buiding a stack of instruments to use. So far: Kenwood HM-250 distortion meter. HP 3562A Dynamic signal analyser. (broken when bought - no display. Fuse in the display electronics was gone) E-MU 0404 Usb audio interface. @juli PCI sound card. ARTA software. Der EE DE-5000 LCR meter. A bunch of MM's. Some parts are still missing though before the measurements can take of. What microphone should I use? I'm an sucker for HP instruments so I added an 5335A frequency counter (I really don't need it but it is cool , bought as a broken unit - oxides and hard to press keys prohibited it from working - fixed). Still looking for cheap 339 and 8903 units. A better oscilloscope is also on the list. Probably an older HP or Tek mainframe with the right options, have to keep the appearence up :D. I also bought an Trimble GPSDO to ensure that the reference frequensies are about spot on. I'm also looking into good enough voltage references as well but I'm not quite ready to buy anything now. Add a bunch of DIY static frequency sinus oscillorators with very clean outputs to set the baseline - the Philips does not count among these and so does not the built in source of the 3562A.
