LabVIEW SDK Block Example

LabVIEW – introduction to SDK examples

PicoScope oscilloscopes

Block mode capture examples

A typical block mode capture vi example is shown.

• The front panel allows you to control acquisition parameters such as timebase, sampling mode and number of pre- and post-trigger samples.
• Triggering controls include trigger source, direction, delay and auto trigger.
• Channel settings controls include channel, voltage range, coupling and DC offset.
• The following actual capture information is displayed: Sample interval, Number of samples, Capture time, and Maximum available.
• Data samples are plotted on the graph.

See 'block capture mode' under the PicoScope A-Z for more information.

LabVIEW SDK Streaming Example

Streaming mode capture examples

A typical streaming mode capture vi example is shown.

• Uses the same basic controls for trigger and channel settings as the block mode examples.
• The front panel allows you to control acquisition parameters including sample interval and time units.
• You can set the size of the Overview buffer for continuous streaming.
• You can enable the Auto Stop button to stop the scope capture once triggered and the required number of samples have been captured.
• Features an Apply Settings button with Auto Stopped and Triggered indicators.
• Actual capture information displayed: Sample interval, Number of samples per Capture and Total Samples.

See 'Streaming mode' under the PicoScope A-Z for more information.

AWG examples

A typical AWG VI example is shown.

• The front panel allows you to control PicoScopes with an AWG or signal generator output.
• Basic signal generator controls: Wave shape, Voltage level and offset, Trigger source and type, sweep settings.
• Shots and sweep settings can be used with trigger modes.
• Separate AWG settings, with AWG file selection feature.
• Additional buttons: Stop, Update, Software trigger and Stop S/W Trigger.

LabVIEW SDK Rapid Block Example

Rapid block mode capture examples

A typical rapid block mode capture VI example is shown.

• Has the same basic controls for trigger, channel, timebase, and number of samples as the block mode examples.
• Has additional acquisition setting for the Number of Captures, which segments the scope's buffer memory.
• Captures can be repetitively started using the Run button.
• Capture Complete indicates the end of all captures.
• Then each capture can be viewed using the capture index.

See 'Rapid trigger mode' under the PicoScope A-Z for more information.

LabVIEW SDK Advanced Triggers Block Example - Mixed signal

Advanced trigger examples

We supply some block mode capture examples using an advanced Triggers vi block.

This front panel shows the use of advanced triggers on a mixed-signal PicoScope (MSO) with analog and digital inputs.

• Trigger conditions let you select channels and the logical condition (AND, OR, and XOR)
• Digital inputs can be set to Don't Care, Low, High, Rising and Falling.

LabVIEW SDK USB TC-08 Example

PicoLog Data Loggers

USB TC-08

A simple vi example controlling our USB TC-08 (8 channel thermocouple data logger).
Supports selectable input types with graph output.

All examples here can be found in the SDK packages on our Github page.
