I was fortunate enough to buy Nortel GPSTM at very good prices. This is a distant cousin of Thunderbird as far as I know. However, it being CDMA clock source, it's second pulse output is actually once every 2 seconds. According to various Internet sources, TP13 on board is 1 PPS. I measured TP13 and it actually IS 1 PPS. However, this test point is giving negative logic. Normally +5V and it goes to 0V every 2 seconds. Manual does not say anything about this being PP2S (with a bar on top).
Has anyone noticed this or am I doing something wrong???? I cascaded two inverters (74AC04) and have used two gates to provide boost to obtain normally 0V and goes to 5V every 1 second. It works but I am baffled. Can anyone tell me what I am seeing is actually the way it is? --------------------------------------- (Mr.) Taka Kamiya I'm stuck in a wormhole....
