TU-5
(Redirected from 015-038)
The Tektronix TU-5 is a tunnel diode pulser designed for checking risetime/bandwidth of probes such as the P6045 FET Probe. It provides nanosecond-risetime pulses when powered from a 100 V scope calibrator square wave.
Key Specifications
| Risetime | Early version ≤1.5 ns, later version ≤1 (typ. 0.5) ns |
|---|---|
| Input | 0/+100 V, 10 mA pulses (−100 V from Type 105 Pulse Generator using an adapter) |
| Output | ≥260 mV into 50 Ω, ~25 Ω source impedance |
| Tunnel diode | Early version (before June 10, 1964), 152-0102-00; later version, 152-0154-00 or 152-0140-01 |
