The Tektronix 214 is a small portable dual-trace analog CRT storage scope with a bandwidth of 500 kHz.
The 214 "Miniscope" was developed by a group led by Dave Allen.
Key Specifications
| Bandwidth | 500 kHz above 10 mV/Div ; 400 kHz @ 5 mV/Div, 200 kHz @ 2 mV/Div, 100 kHz @ 1 mV/Div |
|---|---|
| Deflection | 1 mV/Div to 50 V/Div, 1–2–5 sequence |
| Input impedance | 1 MΩ (integral probes) |
| Writing speed | > 80 Div/ms (500 Div/ms in Automatic Enhance) |
| AC operation | 110 V to 126 V only, max. 3 W |
| Battery | 10 × A size NiCd, 2.5–3.5 hours in store mode, 3.5–5 hours in non-store mode, 8 hours to charge (instrument off) |
| CRT | 154-0695-00 (SN -49999), 154-0732-00 (SN 50000+) |
