Tektronix 214
Portable dual-trace storage scope Tek 214 Produced from 1974 to 1991 Manuals Tektronix 214 Operators Manual, S/N B300000+ Tektronix 214 Service Manual, S/N B300000+ Tektronix 214 Service Manual (OCR) (All manuals in PDF format unless noted otherwise)

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.

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+)
