I've had one since introduced. When coupled with a GPSDO or decent reference, I can't think of anything better for the money. Again, when using with an external reference, it does a respectable job of frequency stability testing (with Timelab). It's small and convenient to move around the lab. There are a number of settings available over the serial port. It would be nice if it had a manual gate and variable voltage trigger level. It would be great if it had A to B and other simple math functions. On that note, I don't know why bg7tbl doesn't make a TIC.
