PD5 piezo driver
The Nanonis piezo driver PD5 combines the low-noise performance of the HVA4 with a ramp generator able to drive slip-stick piezo motors on 8 output lines. Able to drive piezo electrodes with capacitances below 5 nF, the PD5 does not offer the extreme performance of the PMD4, but is a cost-effective replacement for the HVA4 and PMD4 combination for piezo-motors with low capacitance.
Built with the greatest care, the Nanonis piezo driver PD5 has the lowest noise on the market (same as the HVA4) with a measured value below 70μVrms in a bandwidth of 300kHz. Specifically designed for SPM applications, it is perfectly suited for atomic resolution imaging on a STM or AFM set-up.
With X, Y, Z inputs and outputs and 8 coarse motion outputs, the PD5 can handle any type of piezo tube scanner and low-capacitance slip-stick motor. X, Y, and Z have independent turn-on switches with LED indicators. A handset allows operation of coarse motion without software control.
Each axis has 4 selectable gains from 3 predefined set depending on the application: (1, 4, 7, 14); (1, 4, 10, 22) or (1, 4, 15, 40). The actual gain is indicated with an LED on the front panel and digitally read-back by the software for a consistent use. The Z- and AUX- channels have a inverter switch to change output polarity.
