53200 Series Option 010 is available on all models and has accuracy between that of 531xxA Options 010 (available on all
models) and 012 (only available on the 53132A).
Like the 531xxA counters, the 53200 Series also accepts an external reference (1, 5 or 10 MHz) if higher timebase stability
is required. Additionally, the 53200 Series also offers an internal lithium ion battery pack and charger (Option 300) if use
requires disconnecting the counter from power while maintaining timebase stability.
Timebase comparisons
The following table describes and compares the timebases available with each series of counters. Typically, most timebas-
es are compared based on their aging specification - either one month or one year. The 53200 Series comes standard with
a timebase that is of equivalent performance to the Option 001 on the 531xxA model counters. There is one 53200 Series
timebase option: Option 010 Ultra-High Stability Time Base. Although both 53200 Series Option 010 and 531xxA Option 012
are ultra-high stability time bases, Option 012 has the better aging performance of the two.
