I have a Triplett model 7700 frequency counter. It is new in box. See pics attached. Curiously, I can find ZERO info on the web for this instrument. No pictures, no documentation. I reached out to Triplett Corporation Engineering and they only have the Operation Manual which I already have as it came in the box. The internal IC chips have date codes from 1985. It is very well made and accurately measures 10Mhz. I am reaching out to this community in hopes someone has some knowledge about this particular Triplett branded product. My real interest has been in obtaining a schematic. But now I am simply curious to know if anyone in this world has memory of this counter. As for now, it seems it is one of a kind! Let me know if you have knowledge to share regarding this model 7700 Triplett Frequency Counter. |

Nice unit. I hope you find the schematic, but unfortunately I can't be of any help. It reminds me a lot of the Data Precision instruments. Maybe the actual manufacturer is the same. I have a DP 5845 counter (a little older than yours) and I can't find any information about it either. :-// |

The original product was SOAR FC-882, which seems to have been rebadged and supplied to yokogawa same name. SOAR went bankrupt in 1988. http://cooltune.s28.xrea.com/counter.htm |
