Storing

Triggering

Dewesoft X offers extensive triggering capabilities for observing and storing data only at specific events. Any channel (analog, digital, math, CAN, etc.) can be used for setting up the trigger. You can define the start and stop triggers and use pre/post-time for triggering. Several triggers are offered:

• Simple edge: rising or falling slope.
• Filtered edge: edge plus rearm level in either slope.
• Window: two levels - entering or leaving logic.
• Pulsewidth: longer or shorter than duration logic.
• Window and Pulsewidth: completely selectable as above.
• Slope: rising or falling slope with steepness selection.
• Delta amplitude: amplitude variation.
• Relative time:  attaining a particular value

Trigger options

Data is only stored when one or more trigger conditions are met. The software also allows to set pre- and post-trigger time to store data before and after the trigger condition is met.

Since there is no data stored between trigger conditions the amount of stored data is minimized. When analysing the stored data we can easily move between trigger windows and analyse the events. The recorder screen offers cursors for absolute values, time or frequency. Pre and post data analysis of triggered events is possible.

Distributed Acquisition

With the Dewesoft NET option, users can easily control and store data to or from a remote location, as long as your locations are connected with a standard TCP/IP connection. 

Dewesoft NET option serves as a hub for Distributed Data Acquisition Systems. Several DAQ systems can be combined and synchronized together. DAQ systems can be located together or scattered across an entire continent.  Their data can be stored remotely in a single, centralized computer. IRIG and GPS time will take care that data will stay in sync. 

Distributed Acquisition
1:1 mode

This mode works with a single measurement system and a single client. In this mode, there are two kinds of operation:

• full remote control
  
• data view only.
  

In the full remote control mode, the client computer acts as the master of the measurement system. When the client changes into the setup mode, the measurement system also changes into the setup mode.

Distributed Acquisition
X:1 mode

This mode works with multiple measurement systems and a single client. This scenario is useful when you need to distribute your measurements to multiple locations or when the channel count or acquisition rates are too high to be handled by a single measurement unit.

The measurement system has to be clock-synchronized either with hardware clock (one unit serves as a clock master, all other are slaves) or with an external clock source which is either IRIG or GPS. Every measurement systems can run independently even with different sampling rates.

The client is always the master. It starts and stops the acquisition of all measurement units in the network. At any time the client has the access to view mode on one of the selected measurement units. Additional view clients are possible, but they can only view a single measurement unit.

Distributed Acquisition
1:X mode

This mode works with a single measurement system and multiple clients. One of the clients serves as the master client which can have full control over the measurement system. All other clients are view-only clients. 

The master client is able to change the measurement system setup, storing strategy, start and stop acquisition, etc. The other view clients are only allowed to use a few channels from the measurement unit (up to the limit od the bandwidth) to view and store the data on their local hard drives.

Raw data and math channels

Dewesoft X will always store raw data from hardware interface channels and keep it untouched. Any math applied to these channels will result in additional math channels which will not alter the original raw data in any way. 

This allows existing and new math to be changed and applied later in analyze/offline mode easily. No more worries if you forgot to apply or your math was wrong during measurement. Now you always have the capability to change it at any time.
