External Timebase Tests
These tests verify the External Timebase 1, 5, 10 MHz specifications of
the HP 53131A and HP 53181A Counters by checking that TIMEBASE
AUTO allows the Counter to be synchronized to the external reference.
Note that the HP 53132A only operates with the 10 MHz external
timebase; therefore, perform the procedure in the section titled
“10 MHz External Timebase Input for the HP 53132A” on page 1-15
to verify that TIMEBASE AUTO allows the Counter to be synchronized to
the external reference.
