The Type W is a plug-in amplifier for [[500-series scopes]]. | The Type W is a plug-in amplifier for [[500-series scopes]]. Its bandwidth varies from 23MHz to 8MHz | ||
depending on gain. It achieves 20,000 to 1 common-mode rejection at DC and low frequencies. | |||
It 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 Type W has two signal inputs, "A" and "B". A mode switch selects between displaying A-Vc, A-B, or Vc-B. | ||
