Trigger Settings
Controls the trigger conditions under which IVI Soft Front Panels—Scope
acquires a signal. To set the trigger holdoff value, refer to
the Acquire tab in the IVI Soft Front
Panels Scope general settings dialog box.
| Src |
Selects the analog or digital channel that you want to use as a trigger
source.
 |
Note Only those trigger sources that the current instrument
supports appear in this control. |
- Immed—The
oscilloscope does not wait for a trigger of any kind.
- Ext—The
oscilloscope waits for a trigger on an external trigger input.
- Ch x—The
oscilloscope waits for a trigger on the acquisition channel x.
- AC—The oscilloscope
waits for a trigger on the AC line.
- GET—The
oscilloscope waits until it receives a GPIB Group Execute Trigger (GET).
- TTLx —The
oscilloscope waits until it receives a trigger on the PXI TTLx line (for
PXI instruments) or the VXI TTLx line (for VXI instruments).
- ECLx—The
oscilloscope waits for a trigger on the ECL line x.
- Star—The
oscilloscope waits for a trigger on the PXI star bus.
- RTSIx—The oscilloscope waits for a trigger on the RTSI line x.

| Slope |
Selects the slope (rising or falling) required to meet the trigger
condition. |
| Set 50% |
Sets the vertical trigger position to halfway between the min and max values of the trigger channel's input signal. For instance, if a 5V amplitude sine wave with 1V offset (max value is 6V, min value is -4V) is connected to the trigger channel, the Set 50% button sets the vertical trigger position to 1V ((6 - 4) / 2)).
|
Note On External (Ext) channels, clicking this button sets the trigger level to 0 V. |
