W9WIS Waushara County, Wisconsin, USA The HP Z3801A's frequency accuracy is better then 1 X 10 -9 (better then 1 hz in 10 GHz) and has been measured to 1 X 10 -11 (you do the math). It is comparable to a Rubidium frequency standard ! They make a great laboratory standard and their frequency and timing accuracy can be traced to NIST. The Standard has a 10 MHz BNC output and time pulse output on the rear. To learn more about the software which generates this data, please visit K8CU at: www.realhamradio.com
