The Testec TT-SI-8050 is an active differential probe for safe measurements on high-voltage and floating circuits. With selectable 50:1 and 500:1 attenuation, 70MHz bandwidth and 5ns rise time, it is suitable for capturing fast transients and differential signals up to 1500V. The probe is compatible with oscilloscopes from all major manufacturers via a standard BNC connection.
This is a second chance unit. The probe is fully functional but has a number engraved on the back of the housing and the case shows some cosmetic scuffs. These cosmetic marks do not affect usability.
The following original accessories are missing from the case:
| Attenuation | 50:1 / 500:1 |
| Bandwidth | 70 MHz |
| Rise time | 5 ns |
| Input impedance | 5 MΩ / 4 pF |
| Max. differential test input | 150 V (50:1) / 1500 V (500:1) |
| Max. input category | CAT II 1000 V / CAT III 600 V |
| Cable length (BNC to probe) | 1 m |
| Cable length (probe to input leads) | 0.28 m |
| Power supply | 5 V USB (adapter/cable not included for this unit) |
