B-8 Configuring DASYLab for Daq Devices 989593 DASYLab – Standard Driver

Hardware Level Trigger Details:

For “True” oscilloscope simulation, software triggering with DASYLab modules is

recommended, as opposed to hardware triggering.

Note: Hardware triggering is only meaningful when in Series Mode.

• The first channel in the scan list is used (i.e. lowest channel number; main unit = 0-15,

DBK on 0 = 16-31, DBK on 1 = 32-47, etc.)

• DBK7, DBK9, DBK19, DBK42, DBK44, DBK52 excluded.

• Voltage level must equal actual voltage input, not sensor units.

Note: DASYLab modules can also be used to set up software triggers of an infinite variety.

You can set the trigger event to start a continuous measurement, or to perform one conversion for

each channel.

¾ When waiting for a hardware trigger DASYLab will appear frozen until the trigger

event occurs.

¾ Trigger settings are saved in the Configuration File, but not with the worksheet.

DaqBoards and DaqBooks support the following trigger events:

• Immediate

• TTL edge

• Voltage Level on 1st (lowest) channel in scan

In regard to Voltage Level, on 1st (lowest) channel in scan:

◊ TCs and RTDs are excluded.

◊ The value of the Voltage Level entered must be analog.

◊ During measurement, signals from the first activated DASYLab channel will be compared to the

entered analog value.

◊ If the signal value rises above [or falls below] the entered analog value, a trigger event occurs.

Clock Settings

When applicable, the Clock Settings control allows users to select desired timing option.

• the External Clock on P1 can be selected, or

• the A/D settle time can be changed.

Clock Settings

Clock settings are saved in the Configuration File, but not with the worksheet.
