HP 53131A/132A/181A Operational Verification

3Set the HP 8663A to output a 200 MHz, 100 mV sine wave signal to Channel 1.

4On the Counter, Press Run key.

5Send a single pulse by pressing the MAN key on the HP 8130A, and observe that with each press the Gate annunciator flashes.

The Counter should display approximately 1000.

6For HP 53131A/132A, mark Pass or Fail in the HP 53131A/132A Performance Test Record on page 1-41, Test 7.

7Disconnect the test setup.

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.
