Using a Strobe

If you have a strobe light with an output signal it should be possible
to connect it to the tachometer input of the instrument (however,
there are many strobes on the market with different types of output
signal and connectors). If your strobe light has a BNC connector and
gives a TTL output (0 to 5) V you can purchase a suitable cable from
Commtest Instruments Ltd via your distributor.
For other types of connectors and signals please consult the FAQ
(Frequently Asked Questions) articles on the Commtest website
