The Tektronix TG501 is a time mark generator plug-in for the TM500 system.
There is also a TG501A.
Note the output must be terminated into 50 Ω or there may be no signal at all.
Key Specifications
| Interval | 1 ns to 5 s in 1−2−5 sequence |
|---|---|
| Timing accuracy | Stability 1×10-5, long-term drift 1×10-5 per month (with Option 1, 5×10-7 / 1×10-7 per month) |
| Error Readout | Accuracy 1 digit (±0.1% points), Range to ±7.5% |
| Amplitude | ≥1 V peak on 5 s through 10 ns; ≥750 mVp-p on 5 ns and 2 ns; ≥200 mVp-p on 1 ns (separate output) (all into 50 Ω) |
| Trigger Output | Slaved to marker output from 5 s through 100 ns. Remains at 100 ns for all faster markers |
| External Reference Input | 1 MHz, 5 MHz or 10 MHz; TTL compatible (internally hard wired so output frequencies counted down to 1 MHz) |
