Replacement Product: 53220A
The recommended replacement products are the new 53200 Series RF & Universal Frequency Counter/Timers. NOTE: No additional timebase option is required for equivalent Option 001 functionality on the 53200 Series frequency counter.
Transitioning from 53131A, 53132A, 53181A frequency counters to their replacements, the 53200 Series RF and universal frequency counter/timers
Optional timebases improve stability and reduces errors due to changes in temperature or time as well as providing provide the convenience of electronic calibration. You can choose from three OCXO upgrades; option 001, 010 or 012 -- with monthly aging rates of 2 x 10-7, 1.5 x 10-8, and 3 x 10-9 respectively.
Option 001 is our most popular timebase option. It provides an order of magnitude better temperature stability and 33% better monthly aging rate than the standard timebase. Option 010 and 012 provide the best temperature stability 2.5 x 10-9, improved aging rates and better turn-on stability. Other instruments can be synchronized to the timebase signal, provided through a rear panel BNC.
With the frequency oscillator continuously powered, a couple timing errors can be avoided; retrace and shifts in the output frequency. Agilents 53100-Series remain in "standby mode" while plugged-in to prevent the oscillations that happen every time the OCXO power is cycled.
