Info

• Trigger Delay – The time in samples between the logging of the trigger event andbeginning of the count-down of the post-trigger depth counter. This function isuseful for waveforms in which the signal feature of interest occurs long after thetrigger event.Channel Control: An array of clusters of the Channel Setting Controls listed below. TheArray index determines the channel number, starting from 0.• Coupling – A ring control that contains “DC” and “AC” for the two input couplingmodes.• Differential – A button that activates Differential input mode, for CompuScopehardware that supports it.• Direct-to-ADC – A button that activates Direct-to-ADC input mode, forCompuScope hardware that supports it.• Input Range – The full scale input range in millivolts. For instance, for the+/-1 Volt range, enter 2000.• Impedance – An integer control containing 1000000 (1 MOhm) and 50 (50 Ohms)for the two possible input terminations.• DC Offset – The DC offset in millivolts that will be subtracted from the input signal,changing the effective input range. For instance, a 200 mV DC offset will changethe extrema of the +/-1 Volt input range to 0.8 V and -1.2 V. DC offset is notsupported by all CompuScope models.Trigger Control: A Cluster of Trigger Setting Controls• Source – An integer which sets the channel trigger source if one is required.Channel trigger sources begin at 0 (for Channel 1) and can continue up to thenumber of channels available in the system. The Source is used if both theExternal and Disable buttons are not selected.• External – A checkbox that sets the trigger source to be an external trigger. If thisbox is selected, the Source field is ignored and the External Range and ExternalCoupling fields are used. Selecting both the External and Disable checkboxes willcause an error.• Disable – A checkbox that disables the trigger source for the system. If this box isselected, the Source field is ignored and the system will not trigger unlessCsTool-ForceCapture.vi is called. Selecting both the External and Disablecheckboxes will cause an error.• Level – The Trigger Level between +/-100%. The percentage is with respect tothe input range of the trigger source.• Slope – A ring control that sets the trigger slope to “RISING” or “FALLING”.• External Range – List Box – An integer control that sets the full scale externaltrigger input range in millivolts. For instance, for the +/- 5 Volt range, select10000.• External Coupling – A ring control that contains “DC” and “AC” for the two externaltrigger coupling modes.14 CompuScope SDK for LabVIEW for Windows
Transfer Control: Two variables that determine the data to be transferred, once captured:• Start – The point from which to start data transfer. Zero indicates the triggeraddress. Enter a negative value in order to download pre-trigger data.• Points – The number of points to transfer, starting from the Start point.CompuScope SDK for LabVIEW for Windows 15
