The '''Tektronix 7A14''' is a 120 MHz [[7000-series scopes|7000 series]] | The '''Tektronix 7A14''' is a 120 MHz current probe amplifier vertical plug-in for [[7000-series scopes|7000 series]], intended to be used with passive current probes such as the [[P6021]] and [[P6022]]. | ||
The 7A14 is one of the original plug-in modules introduced at the start of the 7000 series in 1969. | 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 | 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. | ||
serves the purpose of detecting the difference between the P6021 and P6022 probes, | The P6021 shorts this ring to ground, directly switching three relays connected to −15 V internally. When connecting a [[P6019]] probe, the ring must also be grounded but the probe connector does not have the matching pin. The [[131-0750-00]] adapter solves this problem. | ||

The P6021 shorts this ring to ground, directly switching three relays connected to −15 V internally. | |||
The front panel gain control screwdriver adjustment affects gain for either P6021 or P6022, i.e. swapping probes requires re-adjustment. | |||
