The Tektronix 7A14 is a 120 MHz current probe amplifier vertical plug-in for 7000-series scopes. It is intended for current probes P6021 and P6022.
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.
Specifications
- Bandwidth: 25 Hz – 50 MHz (P6021 Probe)
- Bandwidth: 250 Hz – 105 MHz (P6022 Probe)
- Ranges: 1 mA/Div to 1 A/Div in 1–2–5 sequence

Internals
The 7A14 uses twelve Tek-made miniature relays that can be a service issue.
