The Z-modulator is specifically designed for adding a low-voltage ac signal to the Z high-voltage output (usually sent to a tube scanner). The ac input connector is a simple BNC and the output is pin-compatible with the SOURIAU connector of the
Nanonis HVA4 (High Voltage Amplifier).
Applications:- Barrier Height Spectroscopy (dI/dZ)
- Transfer function measurement
- Cantilever excitation
