Trigger Interface Board, BNC to Header
- BNC connector provides interface to external trigger source
- 2x8 Header provides interface to oscilloscope digital input port
- Typical application: Connect external trigger source (BNC) to oscilloscope digital input for scope triggering and trigger signal display
General Description and Application
The TRG101 provides a clean, convenient interface to transition from a BNC connection to a header connection. It is ideally suited for connecting an external trigger source (e.g., signal generator) to a digital input on an oscilloscope. This is ideal for use with oscilloscopes that do not have an external trigger input. An added benefit is that the digital input used for triggering can be displayed on the oscilloscope screen. The TRG101 includes a jumper for selecting either high-impedance or 50-Ohm termination for the incoming signal, and also includes a jumper for selecting either AC or DC coupling.
The TRG101 comes with both jumpers installed. The user can easily remove either (or both) if required, based on the particular application configuration.
The rubber-feet version (TRG101-FT) comes with 4 small rubber feet that the user may choose to either install (e.g., benchtop application) or not install (e.g., panel-mount application). The DIN version (TRG101-DIN) comes with DIN clips already installed, ready to snap onto 35mm or 32mm DIN rail.
See datasheet for additional product details.
Please note that it is possible that the connector and header manufacturers and part numbers will vary from batch to batch, resulting in some very slight differences (e.g., overall length of the BNC connector).
If there are any connector dimensions that are critical for a particular application, please consult with Winford Engineering to discuss.

Product Changes
Products with "V2" in the part number (e.g. TRG101V2-DIN) use a slightly different BNC connector. The original BNC connector component used on non-V2 boards was discontinued by the manufacturer, so we substituted an equivalent connector from another manufacturer. The connectors used on V2 boards are slightly shorter, with the center contact of the BNC connectors being about 1.2mm closer to the PCB than on non-V2 boards.
We will update the available part numbers in the Pricing and Ordering table below as we transition from the original versions to the V2 versions.
