The '''155-0059-00''' is a Tek-made HF Amplifier chip. | The '''155-0059-00''' is a Tek-made HF Amplifier chip. The Tek custom chip | ||
catalog calls it a "Gain Trim Amplifier". It's a 12 lead TO-8 package. Used in | |||
the 7000 series 400 MHz and 500 MHz scopes in the vertical amplifier section. | |||
The final vertical gain adjustment is after this amplifier and it typically | |||
leads into either a [[155-0064-00]] or [[155-0065-00]] output amplifier which | |||
drives the vertical deflection plates of the CRT. | |||
Note that this IC can fail by becoming non-linear. It will continue to amplify but | |||
will show non-linear gain and clipping when using a step calibrator. | |||
