[sllug-members]: DDS Waveform Generator

[Chris Brown]

Andrew,

   I'd suggest trying in this order:

   * Standard Supply Electronics Co
      3424S Main St
      SLC UT 84115
      (801)486-3371
      http://www.standardsupply.com

   * Ballard Supply Co
      2430S 900 West
      SLC UT 84119
      (801)972-2430
      http://www.ballardsupply.com

   * RaElCo
      2780 South Main Street
      Salt Lake City, UT 84115
      (801)487-0571
      email: raelco at aol.com

Or if you'd like an old analog signal generator, I have one available free.
