The GTP-150B-2 is a passive high impedance oscilloscope probe designed and calibrated for use on instrument having an input impedance of 1M? shunted by 20pF. However, it may be compensated for use with instruments having an input capacitance of 10-30pF. The probe incorporates a two position slide switch in the head which selects attenuation of x1,x10 position.
Instek GTP-100B-4 100 MHz Oscilloscope BNC(P/M) Probe for GDS/GOS/GRS Series. Passive high impedance oscilloscope probe designed and calibrated for use on instruments having an input impedance of 1M? shunted by 20pF. However, it may be compensated for use with instruments having an input capacitance of a 10-35pF. The probe incorporates a two position slide switch in the head which selects attenuation of x1, x10 position.
