New features for Nanonis lock-in modules

Synchronize external instruments with the internal lock-in modules

All lock-in modules now feature a synchronized output option. In addition to the main signal output, the lock-in module can generate a synchronization signal with the main frequency. The amplitude can be configured independently from that of the main signal, and it is also possible to use harmonics of the main signal frequency as a synchronization signal. The new feature is used to synchronize external instruments (for example other lock-ins, optical choppers,…) with the frequency of the internal lock-in. The output connector for the synchronization signal is user-selectable.

Use the advanced lock-in high- and low-pass filters for filtering any signal

The Nanonis lock-in modules use complex filters to ensure optimal signal to noise ratio for lock-in measurements. The filter array is now also available for signals unrelated to lock-in measurements. Low-pass filters with up to 8th order and time constants between approximately 8 µs and 2 s and a 1st-order high-pass can be applied to any input or output signal. The filters in the array are freely assignable, meaning that it is possible to use a subset of the filters for lock-in measurements and the remaining filters for generic purposes.
