nanoZ User Manual

number of samples returned by the getplatingdata function and stop plating when

the prescribed number of samples has been acquired.

If, for whatever reason, the user application crashes during electroplating the

nanoZ device will not be informed of it and will continue to supply electroplating

current to the target electrode. For this reason it is a good idea to encapsulate

electroplating sections of the Matlab code in try/catch clauses, in order to ensure

that electroplating is stopped in all cases, even if an error occurs. The most

reliable way to stop electroplating without generating further errors is to execute a

clear nanoz Matlab statement.

getplatingdata

Retrieves electroplating voltage feedback data.

Usage: voltage = nanoz(‘getplatingdata’, handle);

Arguments: handle – handle to an opened device returned by the open function.

Return value: voltage – a vector of voltage values measured across the target

electrode during electroplating. Units are in volts.

Remarks: During electroplating the nanoZ monitors the voltage on the target

channel. This voltage is sampled at the frequency that is returned by the

getwaveformcaps function.

This function returns all samples that have been collected since electroplating

was started, or from the time this function was previously called. It may be an

empty matrix if no new values were acquired.

The user application should call this function every ~30ms or a data overrun may

result. The total number of samples returned by this function since electroplating

was started can be used to determine the exact electroplating duration.

Values returned by this function take into account device calibration, and have

units of volts.

stop

Stops impedance metering or electroplating.

Usage: nanoz(‘stop’, handle);

Arguments: handle – handle to an opened device returned by the open function.

Return value: none.
