Product Description The P6205 Probe provides high-frequency measurement capability without the capacitive loading and performance limitations inherent in passive resistive-divider type Probe FETs are used in the P6205 to establish the characteristic high input impedance at high frequency of an active Probe The P6205 features a 750 MHz bandwidth with an input impedance of 1 MW in parallel with 2 pF. You must terminate the P6205 Probe output into 50 W. The P6205 includes the TEKPROBEt Level 2 Interface When used with a fully TEKPROBE Interface compatible Oscilloscope the P6205 Probe is powered by the host instrument and provides the Oscilloscope with the Probe model number, serial number, and attenuation factor. When installed on a fully compatible oscillo- scope, the Oscilloscope channel input is automatically set to 50 W and the display readouts are corrected for the Probe attenuation factor Oscilloscope without the TEKPROBE Interface The P6205 is an active Probe that requires external power to operate. If your Oscilloscope is not equipped with the TEKPROBE Interface we recommend that you use the Tektronix 1103 TEKPROBE Power Supply. By connecting the Probe to the 1103 Power Supply and the Power Supply output to your Oscilloscope input, you can use the P6205 Probe with Oscilloscope having conventional BNC inputs. The 1103 can power two P6205 Probe imultaneously. To maintain the best possible high-frequency response with the 1103 Power Supply keep the cable connecting the 1103 output to the Oscilloscope input as short as possible. You must use an Oscilloscope with 50 W input impedance with this system.
