Internal Trigger signal In early 500-series systems (e.g., a Type C plug-in in a 535 mainframe), the mainframe's triggering is based on the main vertical signal sent by the plug-in to the mainframe on pins 1 and 3. In these scopes,changing the vertical position control on the plug-in interacts with the trigger level setting if the scope is set to a DC trigger mode. In somewhat later 500-series systems, the plug-in (e.g., Type 1A1) provides the mainframe (e.g., Type 547) with a trigger signal on pin 5, separate from the main vertical signal. The vertical position knob on the plug-in doesn't affect the DC level on the trigger signal sent from the plug-in to the mainframe. This allows, in multi-trace setups, for the operator to consistently trigger from a specific input channel independent of which channel is currently being drawn on CRT. Although the Type 1A1 has two input channels, they are not identical. Only the channel 1 signal is sent to the mainframe on pin 5. The 547 has two types of INT triggering, differing in whether the mainframe's trigger circuit is fed by the pin 1,3 (main vertical) output of the plug-in or the pin 5 (trigger signal) output. In even later 500-series plug-ins (e.g., the Type 1A4), the plug-in has a knob for the selection of which input channel's signal will be sent to the mainframe as the trigger signal. |
