True-Time (now Symmetricom) used to make an IRIG timecode card for ISA bus, for instance. I imagine these are in the $1000 range. For instance the National Instruments PCI-6601 counter timer card is about $350 Then, drive that with Rb standard from Stanford Research (I seem to recall seeing ads on the back of Electronic Design or some such for $1795)... That's all brand new. One can do much better if one hunts down surplus or used.
