The P6032 is | The '''Tektronix P6032''' is an 850 MHz cathode-follower probe, intended for use with samplers such as the [[1S1]], [[3S1]], [[3S76]] and [[4S1]]. | ||
It was designed by [[Murlan Kaufman]]. | |||
There is an [[EC1000]] subminiature triode in the probe body, which is why it gets slightly warm during operation. | |||
Like all active probes, the P6032 requires power, and for this reason it has two connectors at the scope end of cable. | |||
There is a four-pin power connector and a 50 Ω [[GR-874 connector]] for the signal. | |||
The triode has limited dynamic range, so attenuator attachments are provided that attach to the tip of the probe. | |||
These attenuators also reduce the loading of the probe on the probed circuit. | |||
What, exactly, does the clipping line in the probe body do? | |||
It appears to be 21 mm of RG-174 cable connected to the triode's cathode at one end, and open at the other end. | |||
The circuit description in the manual describes it vaguely, saying only that, "The clipping line reduces signal aberration to a minimum." | |||
