The '''Tektronix Type 5T3''' is a timing plug-in for the Type [[661]] [[sampling oscilloscope]]. | |||
It uses [[TD253|TD253B]] [[tunnel diodes]] for triggering. | |||
The 5T3 can be triggered from any of four different sources: | |||
* | # Internal trigger from the sampling plug-in, via interconnect J9. | ||
# Internal trigger from the calibrator module in the 661 mainframe. This works up to 1 GHz. | |||
# External trigger to the high-impedance BNC trigger input. This input is buffered by an [[8056]] [[nuvistor|Nuvistor]] cathode follower. This can be used for triggering on signals up to 20 MHz. | |||
# External trigger to the 50 Ω [[GR-874]] trigger input. This input can drive either of two selectable signal paths: | |||
#* A path where the trigger signal skips the high-impedance Nuvistor input buffer but is still buffered by Q64 and Q124 (1 GHz NPN transistors, part number [[151-0138-00]]) before the tunnel diode trigger event recognizer circuit. This path provides triggering up to 500 MHz. | |||
#* A passive low-impedance path, capacitively coupled to a tunnel diode for "UHF SYNC" mode. This works up to 5 GHz. | |||
The 5T3 can also be set to free-run mode. | |||
