Z Modulator

Add an AC modulation to the Z high voltage signal

The Z-modulator is specifically designed for adding a low-voltage AC signal to the Z high-voltage output, when the required bandiwdth exceeds that of the HVA4. The signal is then 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).

  • Add ac modulation to Z high voltage signal
  • No deterioration of HVA4 noise performance
  • Bandwidth up to 100kHz
  • Pin compatible with HVA4 output

Typical applications:

  • Barrier Height Spectroscopy (dI/dZ)
  • Transfer function measurement
  • Cantilever excitation
