The '''Tektronix 7A14''' is a 120 MHz current probe amplifier vertical plug-in | The '''Tektronix 7A14''' is a 120 MHz current probe amplifier vertical plug-in intended to use current probes [[P6021]] and [[P6022]] with [[7000-series scopes]]. The 7A14 is one of the original plug-in modules introduced at the start of the 7000 series in 1969. | ||
In the 7A14, the ring around the input [[BNC connector]] that is used to identify ×10/×100 probes on voltage probes serves the purpose of detecting the difference between the P6021 and P6022 probes, and switching in appropriate gain and frequency compensation. The P6021 shorts this ring to ground, directly switching three relays connected to -15 V internally. | In the 7A14, the ring around the input [[BNC connector]] that is used to identify ×10/×100 probes on voltage probes serves the purpose of detecting the difference between the P6021 and P6022 probes, and switching in appropriate gain and frequency compensation.
