HP5370B

The HP5370B is a time interval and frequency counter, capable of measuring time intervals as small as 20 picoseconds. Time intervals up to ±10 seconds can be measured with 20 ps relative accuracy, and 65 Ps absolute accuracy, assuming a 'stable' external timebase (frequency) is used. A rear-panel input lets you connect any external 5 MHz or 10 MHz source as a timebase. Statistics are automatically calculated and reported on samples as large as 100,000, including: sample mean, maximum, minimum, and standard deviation. Standard GPIB interfaces control all front panel functions, and printers can be directly connected to the HP5370B.

Its ease of use, relativity low cost, and its relativity good linearity and absolute accuracy characteristics are the primary reasons, many ILRS stations use the HP5370B as their primary range-measuring instrument, and other stations have access to them. The prime drawback of the HP5370B is no longer made and Agilent Technologies (formerly HP) will discontinue its support on 1 August 2004, however; refurbished units can still be purchased. Another drawback for SLR applications is it's maximum laser repetition rate of 10Hz.

The General TOF Device BEST Practices also apply to the HP5370B.
