For fine-tuning, user can then adjust the digital offset to your application. For instance, in 1 V range,

moving the digital offset of +/-1 LSB is equivalent to move the trace of +/-15.26 uV.

5. Enter the baseline stabilization parameters previously determined and set the Mode to Continuous

for channel 1 and channel 2 (even if only one channel is used) and starts the measurements.

The example below uses the averager mode (-AVG option required) with 10000 averages.

Configuration of the baseline stabilization parameters in a custom

application

We recommend adjusting the baseline stabilization parameters (Pulse Polarity, Pulse Threshold and

Digital Offset) with the SFP and once the parameters are determined, you can configure the baseline

stabilization in your application.

From the previous example, you will find below some C++ (using the IVI-C driver) and C# (using the

IVI.NET driver) code snippet to configure the baseline stabilization on Channel 1 in your application.

Using the AqMD3 IVI-C driver

ViInt32 const baselineMode = AQMD3_VAL_BASELINE_CORRECTION_MODE_CONTINUOUS; // use AQMD3_VAL_

BASELINE_CORRECTION_MODE_DISABLED to disable the baseline stabilization

ViInt32 const pulsePolarity = AQMD3_VAL_BASELINE_CORRECTION_PULSE_POLARITY_NEGATIVE; // use

AQMD3_VAL_BASELINE_CORRECTION_PULSE_POLARITY_POSITIVE for positive pulses

ViInt32 const pulseThreshold = 32320;

ViInt32 const digitalOffset = 32506;

Using the ChannelBaselineCorrectionConfigure function
