[time-nuts] What are HP High Stability Oscillators (Option 1D5 in 8720D VNA)

2012-08-27 Thread David Kirkby
I recently bought an HP 8720D 20 GHz VNA with options 010 (TDR facility) and 1D5, which is the high stability time base. It's a fairly old VNA (not supported since 2004), but it's not exactly a dinosaur Accuracy (23 deg C +/- 3 deg C) 10 ppm The standard oscillator specs are: Stability 0 - 55
