The '''Tektronix C-50, C-51, C-52 and C-53''' are oscilloscope cameras primarily targeted toward the [[7000-series scopes]] but also compatible with other instruments through mounting adapters. The cameras used interchangeable packs for 120 roll film, Polaroid pack film, or 4" × 5" film. | The '''Tektronix C-50, C-51, C-52 and C-53''' are oscilloscope cameras primarily targeted toward the [[7000-series scopes]] | ||

120 roll film, Polaroid pack film, or 4" × 5" film. | |||
The cameras have a three-pin connector matching the 7000 series camera connectors to t he left of the CRT. | |||
This connector carries 15 V power, Ground, and a sweep reset signal from the camera to the scope. In single sweep mode, | |||
pressing the shutter button on the camera opens the shutter and signals the sweep reset, arming the timebase's sweep; | |||
the scope's GATE output, connected to the camera's GATE input, closes the shutter 5 seconds after the sweep is complete. | |||
The cameras also have NC and NO sync contacts (actuated by the shutter) that can be used e.g. to advance a | |||
frame counter when connected to a [[7M13]]'s sync jack. | |||
