    Description

    For sale is a piece of history, a
    Bruno Weinschel  SPA-1 30 MHz Standard Piston Attenuator
    .  This was what was considered to be a primary attenuator used in the Weinschel VM-3 Attenuation Measuring Systems up until the early 90's.  Resolution is .005dB.  This is the first one of these I've ever had.  Generally these were the primary standard included in the Weinschel VM-3 System.  Looks to be either unused or it has been taken care of in a way that's not what you usually find even in calibration facilities.  Serial number is '4'.
