This is a sophisticated active 8-way reference signal distributor. The FDIS-8-8 model includes a 10 MHz signal distributor with the option of generating 1PPS. If you also connect a 1PPS signal to the input, it will switch from 10 MHz (divider) and distribute this signal as well - see the manual for connection details. Both the 10 MHz and 1PPS inputs include a detector and LED indication. The output signals are shaped and filtered, with the 10 MHz outputs including BPF filters. The 1PPS input is high impedance and therefore does not load the output from the signal source (GPS, GPSDO, etc.).

This is a model without a built-in TCXO - the distributed signal(s) must be connected to the input. It is an ideal distributor of reference signals for synchronized SDRs, measuring instruments, and laboratories.

1PPS Output voltage

You can set the output PPS voltage as needed. The 3V3 voltage should be "universal." However, if you need 5V, you must open the device and re-solder the shorting resistor from R69 to R67.

âš  The short at position R69 sets 3V3, R67 sets 5V. Never connect both at the same time.
