It has been suggested to me that the PG503 has no version with BNC pulse outputs, and the BNC pulse outputs shown in the photo are screw-on adapters mating with the SMA connectors in the PG503's front panel. If, in fact, there is no version of PG503 with BNC pulse output connectors, we should correct the text in the page. Kurt (talk) 13:56, 26 April 2020 (PDT)
I removed the mention of a version with BNC pulse output connectors. Kurt (talk) 13:04, 27 April 2020 (PDT)
