Designed primarily for use with 50-Ω sampling instruments.
However the 1973 catalog lists 475, 485, 7500, 7700 and 7900.
The P6051 is an active (FET) probe providing DC to 1 GHz bandwidth. The low input-capacitance of the probe
permits coupling of high-frequency signals to an oscilloscope input with minimum loading on the circuit under
test.
The P6051 is designed primarily for use with 50-Ω sampling instruments. An external 50-Ω termination
may be used to adapt the probe output to 1-MΩ inputs. The probe also features a DC-offset control for
measuring small AC signals with DC potentials up to 5 volts (200V with the 40X attenuator).
The P6051 can be powered from the probe power output of the 475, 485, 7500, 7700 and 7900-Series mainframes,
also by the 015-0073-00 power supply or by the 1101 Accessory Power Supply.
