External Timebase Test
This test verifies the 10 MHz external timebase specifications of the
Counter by verifying that setting
REF OSC
to
EXT
allows the Counter to
be synchronized to the external reference signal.
Equipment Required
Agilent 3325A/B Synthesizer (2)
Agilent 10100C 50
Ω
Feedthrough Terminator
Agilent 10503 Series Coaxial Cables (BNC m to m) (2)
NOTES • To ensure that the test results are valid, the Counter and the test
equipment should be powered on for at least 30 minutes prior to
beginning the tests. This allows the internal temperatures of the
equipment to stabilize.
• These tests are appropriate for the Agilent 53150A, 53151A, and
53152A Counters.
10 MHz External Timebase Input Test
1 Connect an Agilent 10503 series coaxial cable between the output of the
first Agilent 3325A/B Synthesizer and the
Reference 10MHz connector on
the Counter’s rear panel (see Figure 1-2).
2 Connect the Agilent 10100C 50
Ω
Feedthrough Terminator to the
Counter’s CHANNEL 1 input connector.
3 Connect an Agilent 10503 series coaxial cable between the output of the
second Synthesizer and the Agilent 10100C 50
Ω
Feedthrough Terminator
on the Counter’s CHANNEL 1 input connector.
