P6158 DC to 3 GHz
The P6158 is a 3 GHz, 20X, low-capacitance probe. The P6158 is ideal for high-speed applications because of its ability to extend high-frequency response to 3 GHz. The BNC connector incorporates encoding to correct scale factors for 20X attenuation in oscilloscopes with TEKPROBE® power supply interface. To facilitate SMD probing, the P6158 comes standard with SureFoot® adapters. Additionally, the probe comes standard with an array of short ground leads that insert minimal inductance into the signal path of the measured waveform. The compact probe head/tip assembly is compatible with the full line of 3.5 mm probe accessories. Designed for the TDS500/600/700/5000/6000/7000 Series oscilloscopes, the P6158 probe may also be used with 50 Ω 11000 Series plug-ins and the 11800 Series SD2X Sampling/TDR plug-ins with BNC to SMA Adapters.
