generator sample rate. Using the maximum 1024x interpolation factor (8x linear +

128x hold), frequencies down to 0.645Hz can be generated.

For impedance measurement, the MEX library automatically chooses the best

interpolation factor and synthesizes a waveform of appropriate length, to achieve

a test signal frequency as close as possible to that specified by the user. For

electroplating, arbitrary user-supplied waveforms may be used, which puts the

responsibility of choosing waveform length and interpolation factor on the user

application.

getplatingcaps

Returns information about electroplating capabilities.

Usage: caps = nanoz(‘getplatingcaps’, handle);

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

Return value: caps – a Matlab structure with the following fields:

min_current The minimum (negative) current, in amperes, which the nanoZ's

electroplating current source can generate.

max_current The maximum (positive) current, in amperes, which the nanoZ's

electroplating current source can generate.

current_step The minimum step size, in amperes, by which the requested

electroplating current can be decreased or increased.

min_voltage The minimum (negative) voltage, which can be produced by

nanoZ to maintain the requested current (i.e. negative voltage compliance).

max_voltage The maximum (positive) voltage, which can be produced by

nanoZ to maintain the requested current (i.e. positive voltage compliance).

Remarks: The values returned by this function reflect the device's calibration

status, not just the design specifications, and can therefore vary slightly from

device to device.

preparewaveform

Prepares a waveform for electroplating.

Usage: [output_waveform, achieved_current] = nanoz(‘preparewaveform’, handle,

desired_waveform);

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