The Type W is a plug-in amplifier for 500-series scopes. Has a built in precision variable voltage supply, "Vc". The Type W has two signal inputs, "A" and "B". A mode switch selects between displaying A-Vc, A-B, or Vc-B. The "A-B" mode is particularly useful for displaying the current in a sense resistor, while the other modes provide "slideback" measurements of small variations superimposed on a large constant. An output of Vc is provided on the front panel of the Type W. | The Type W is a plug-in amplifier for 500-series scopes. Has a built in precision variable voltage supply, "Vc".
