| outer sector | |
| 150 to 500 Hz | blade only: 0.5%; blade + electronics: 1.5% |
| 500 to 3000 Hz | blade only: 0.5%; blade + electronics: 1.0% |
| inner sector | |
| 15 to 50 Hz | blade only: 0.5%; blade + electronics: 1.5% |
| 50 to 300 Hz | blade only: 0.5%; blade + electronics: 1.0% |
| Lock indication | Bicolor LED, showing Red when unlocked and Green when locked |
| Settling Time | 7 s nominal at 1 kHz from switch-on;
9 s nominal for frequency change from 150 to 3000 Hz;
30 s nominal for frequency change from 3000 to 150 Hz |
Outputs | Sync Out 1 | 10 V pk-pk squarewave at outer sector chopping frequency, 150 - 3000 Hz |
| Sync Out 2 | 10 V pk-pk squarewave at inner sector chopping frequency, 15 - 300 Hz |
| Connectors | BNC |
| Impedance | 10 kW. Note that although the output voltage is 10 V pk-pk, the high output impedance means that the outputs can be directly connected to the Reference Frequency input of any SIGNAL RECOVERY lock-in amplifier without causing problems. |
