HELP? Message-ID: <2230.27ad7857@idx.com> Date: 4 Feb 91 15:05:58 GMT Organization: IDX Corporation, S. Burlington, VT Lines: 32 Can anyone pass on any information of the HP 581B (or was it 531B) spectrum analyzer display unit. (I'm sorry, it is at home, and my memory is having parity errors!)... The unit seems to have a BNC connector on the read marked "IF in". The unit itself seems to work (I get a base line, and can induce a few deflections with a signal generator).. It has a 5" crt, and bandwidth switches as well as an IF gain control. My questions are: What is the center of the IF expected for this unit, and would the unit itself serve as a panadaptor type display unit (spectral display about the IF center frequency) without additional equipment on a Shortwave radio with suitable IF frequency and bandwidth? And, what are the other items of the Spectrum Analyzer to which this belongs? I assume that there is a companion unit (with plug-ins?) which act as a "reciever" of the signal to be analized? I have stumbled into one of these at an exceedingly reasonable price, and may be able to acquire more, and am trying to find a use for them.. However, if they won't do what I want, then any price is too much! (B->)! Thanks for any help you can pass on.... -- -- George -- ------------------------------------------------------------------ - George Kaczowka IDX Corp Marlboro, MA - gsk@ziggy.idx.com - ------------------------------------------------------------------
