DXD Storing

Storing DXD RT saves selected signals as Dewesoft .dxd files on the device’s configured storage medium. Use DewesoftX to select channels, set the recording options, and retrieve the files.

Available settings depend on the device firmware and DewesoftX version.

1. Open the storing configuration

Select the device in DewesoftX, then open Config → Storing. Here you can select the channels to record, change the recording options, and check storage usage. Each storing instance has its own tab, such as Dxd storing 1.

Figure 1. Storing configuration with channel selection, storage usage, and recording options.

Multiple storing engines

Here you can create several DXD storing instances on the same device. Configure the channel selection, recording mode, filename template, file splitting, and cyclic retention separately for each instance. Files are stored in separate instance folders, such as DSStoringDxd_1 and DSStoringDxd_2.

Select + beside the storing tabs and choose Dxd storing to add an instance. Open its tab to configure it. Check the channel selection before recording: a new instance can already have signals selected.

Use separate instances to record different channel groups or apply different continuous and triggered recording settings. All instances share the device’s operation state and available storage resources.

Figure 2. Multiple storing instances. Select a tab to configure that instance.

2. Select signals

In the Signals list, check each signal you want to record. Here you can select acquisition channels and outputs from processing blocks running on the device.

Select stored channels in the Channels module

Open Config → Channels to manage the recording selection in a table. If the module is not visible, open More…, then select Channels.

Find the column named after the required storing engine, such as Dxd storing 1. Here you can set each channel to Stored or Not stored. Review the same channel selection on the engine’s Storing tab.

The Used and storing columns are separate. A channel can be Used while set to Not stored. Stored means the channel is included in the recording configuration; check the green Storing indicator to confirm that recording is running.

Figure 3. Stored and Not stored switches in the Channels module.

3. Set the recording mode

Here you can change the Storing type to control when data is recorded and at which rate. Select one of the following options:

DewesoftX option	Recording behavior
Off	Disables recording for this instance.
Always fast	Records continuously at the full input sample rate.
Always slow	Records continuously at a reduced rate.
Fast on trigger	Records full-rate data in triggered regions. Stores no data between them.
Fast on trigger, slow otherwise	Records full-rate data in triggered regions and reduced-rate data between them.

The reduced recording rate depends on the firmware and signal configuration.

Storing runs in Operation mode and stops when the device leaves that mode. Setting a recording mode configures the engine; check the device state and storing status to confirm that it is recording. See the recording behavior reference.

Check that recording is active

Check the device status area in the upper-right corner of DewesoftX. Here you can see whether recording is active. During recording, Storing is green and the device mode reads Operation.

Operation means the device is running. Check Storing as well, because live traces can appear without data being written. With multiple engines, check each instance’s settings and files to identify what it records. The device-level indicator does not confirm every instance separately.

Figure 4. The full DewesoftX window during recording. Storing is green beside Operation in the upper-right corner. Y-axis Auto scale is enabled for the recorder.

If the indicator reads Not storing, check the recording type, channel selection, destination, available space, and reported errors. A triggered engine may be waiting for its start condition. After stopping, check that the file appears as Finished in the device browser or Analysis mode.

4. Configure triggered recording

Choose Fast on trigger or Fast on trigger, slow otherwise to show Trigger setup. Here you can define when recording starts, when it stops, and when start triggers are suppressed.

UI section	Purpose
Start storing conditions	Define when a recording event starts.
Stop storing conditions	Define when the event ends.
“Don’t store” conditions	Suppress start triggers in specified time or signal regions.

Use Add trigger in the required section, then open Setup to edit the condition. Use Remove trigger to remove a condition.

Set up a condition

Open Condition setup. Here you can choose Data or Time under Trig type, then configure the condition.

For a Data condition, select the Input signal and Mode. The mode list includes Level, Window, and Pulse width. A Level condition has a Trig level and a Direction of Positive or Negative. Choose the Value to evaluate: Real data, Average, RMS, Min, or Max. The dialog also has Edge options and a Trigger on first sample checkbox.

For a Time condition, choose Relative, Absolute (time only), or Absolute (time and date) under Timer mode. With Relative timing, use equal to for a single time or every for a repeating interval, then enter the time.

Set the recording times

In Trigger setup, enter the recording times in milliseconds:

UI setting	Purpose
Pre time	Includes data from before the start trigger.
Post time	Continues recording after the stop condition.
Hold off time	Sets the minimum time after a trigger before another can fire.

Enable cross trigger

Select Cross trigger (send and receive network start triggers) to exchange start triggers between devices over the network.

5. Choose a storage destination

Under Storing location, select where the device will save recordings. Available destinations can include an Internal drive and an SD Card, depending on the device. Here you can check the capacity and usage of each medium. Use Browse to view files or Eject where the medium supports it.

Files are organized by storage medium and storing instance. Use Browse or Analyze → Data files to access them.

6. Set filenames

Here you can change how recording files are named. Choose Custom filename or Copy Dewesoft X filename. For a custom name, enter the template directly or open Name editor. Use the presets, date and time components, and counter to build the name, then check the filename preview.

Figure 5. Name editor with filename components and a preview.

Token	Meaning
{YYYY}	Four-digit year
{mm}	Two-digit month
{DD}	Two-digit day
{HH}	Hour in 24-hour format
{MM}	Minute
{SS}	Second
{count N}	Counter starting at N, padded to four digits by default
{count N P}	Counter starting at N, padded to P digits

The tokens are case sensitive: {mm} is the month and {MM} is the minute.

The default template is:

datafile_{YYYY}{mm}{DD}-{HH}{MM}_{count 1}

The editor shows the .dxd extension separately. Check the preview before applying the filename. See the filename-template reference.

7. Set recording limits and file splitting

Here you can set a recording limit or create new files automatically during recording.

DewesoftX option	Behavior
No storing limit	Uses one file without a configured split or stop threshold. Available storage still limits recording.
Stop storing after	Stops recording at the entered limit.
Make a new file after	Opens a new file at the entered limit and continues recording.

After choosing Stop storing after or Make a new file after, enter the limit and choose its unit. The unit selector has MB, sec, min, h, and trig.

Use a time limit to divide a long recording into shorter files. File splitting sets file boundaries; trigger conditions determine which time regions are recorded.

8. Set cyclic retention

Here you can choose whether older files are kept or deleted as recording continues.

DewesoftX option	Behavior
Stop when disk is full	Keeps existing files and does not delete them cyclically.
Keep only last	Retains the configured number of recent files and removes older files managed by the instance.
Delete oldest file on full disk	Deletes the oldest file when storage is full.

With Keep only last, set the number of files to retain. Combine this option with Make a new file after to maintain a rolling set of recordings. Monitor the storage usage and storing status during long recordings.

9. Browse and retrieve recordings

Select Browse beside a storage medium to open Files on device. Here you can search for recordings, check their status, and select files to download or delete.

Figure 6. Files on device with recording details and file actions.

Search for files or switch between Full details, Quick list, and Drive root views. Select files to Download or Delete them. Download recordings to the PC for work in DewesoftX, and delete device files when they are no longer needed.

Access files in Analysis mode

Open Analyze → Data files and select the device in the left sidebar. Expand Device, choose Internal drive or SD Card, then select the instance folder, such as DSStoringDxd_1.

Here you can check the filename, size, start store time, and status of each recording. Expand a grouped recording to see its files. Select a file to use the available Download, Load, or Delete actions.
