This page shows where the plugin appears in DataLab, how to run the demo campaign, and how to prepare your own signals. DataLab Desktop and DataLab-Web work the same way.
- Plugins > Pulse & Transient Characterization menu of the signal panel: open the examples, run the methods and open the oscilloscope simulator.
- Applications catalog, opened by the Pulse & Transient Characterization tile of the welcome page. It lists each method with the inputs it expects, tells whether the current selection can run it, and offers its examples. Try with this example opens an example, prefills the parameters and runs the method.
- Open demo campaign tile of the welcome page.
- Choose Plugins > Pulse & Transient Characterization > Open demo campaign. DataLab generates 500 synthetic shots and selects them.
- Choose Run pulse campaign....
- Accept the parameters.
DataLab adds the amplitude versus shot with a per-shot metrics table, and the raw and aligned mean pulses. The amplitude shows a slow drift and the 11 deliberate anomalies of the campaign. Single-channel pulse campaign explains each result.
Each method checks the selection before the run: shot numbers, number of shots, samples per step, common X unit for two channels. DataLab asks you to assign the signals only when the selection is ambiguous or invalid.
| Menu item | Example | Methods |
|---|---|---|
| Open stability example | Laser warm-up: 600 pulses with drifts and a jitter increase | Shot-to-shot stability, pulse campaign |
| Open step-response example | 64 steps of an 80 MHz amplifier with a 0.35 damping ratio | Step response |
| Open two-channel example | Reference and detector channels, 1 ns common and 0.2 ns detector jitter | Two-channel delay |
| Open gamma spectrum example | NaI(Tl) events from Cs-137 and Co-60 sources | Pulse-height spectrum |
All examples are generated in memory. Run them with the matching Run ... item of the menu.
The methods read two metadata entries on each signal:
| Key | Value | Use |
|---|---|---|
plugin.org.datalab.pulse-characterization.shot |
Positive integer shot number | Required by the two-channel method, which pairs shots by this number. Optional elsewhere: the input order gives the shot number |
plugin.org.datalab.pulse-characterization.channel |
Channel label, for instance CH1 |
Optional. The two-channel method uses it to propose the reference and measured channels |
Set them with Edit > Metadata > Add metadata.... While the plugin is active, the Known keys list offers both keys. When a key is missing, the method status in the Applications catalog points to this dialog.
To read the shot number from titles such as CH1 shot 001, select the signals and set:
| Field | Value |
|---|---|
| Metadata key | plugin.org.datalab.pulse-characterization.shot |
| Value pattern | {title} |
| Extraction pattern | shot\s*(\d+) |
| Conversion | Integer |
CH1 shot 001 gives 1. The preview shows each value before you click OK. When the signals are already in shot order, the value pattern {index} numbers them 1, 2, 3... in the order of the selection.
For the channel label, use the extraction pattern ^(CH\d+), the String conversion and the key plugin.org.datalab.pulse-characterization.channel. You can also select the signals of one channel and type its label, for instance CH1, as the value pattern; then repeat for the other channel.
