Bei einer 10:1 Probe würde ich einen kompensierten 5:1 Teiler vor den OpAmp setzten und dan mit 50Ohm (eventuell ebenfalls kompensiert) in Serie aufs Kabel gehen. De HP probe deed het trouwens erg goed. cz Tue Jun 1 04:24:09 2004 From: steebe at seznam. D1 protects the probe in the event of the supply leads being reversed.

The small loop antenna is a loop as shown in Figure 1. A dual-gate MOSFET guarantees light, uniform loading of RF signals over a frequency range extending well. Symbol: xdgnmos. Shipping: + $3. 15w b>60 2n1613 si-n 75v 1a 0. I found a probe based on BF998 but the its nonliearity is too high. Electromagnetic Field Probe with Meter Output using an LF351 opamp ; Electronic canary doorbell ; Electronic dazer ; Electronic inclinometer ("clino"), a surveying device ; Fantastic Atom Expander ; FCTS Project ; FET based metal detector using MPF102 / J310 BF998 FETs ; Fish caller circuit ; Fluid level detector ; FM Morse Code Keyer. FET based metal Detector using MPF102 / J310 BF998 FETs - Making a metal detector was always my dream. Audio IC amplifier is LM386 which drives a speaker. The probe can tolerate DC input levels of at least 100V DC due to the PCB gimmick cap used at the input. 8w 2n2102 si-n 120v 1a 1w <120mhz 2n2148 ge-p 60v 5a 12. The probe is roughly 1:10, as a lot of passive probes.
