Test 1: Channel 1 Frequency Sensitivity

Test 1: Channel 1 Frequency Sensitivity
This set of tests verifies the frequency-sensitivity specifications of
Channel 1 of the Agilent 53147A/148A/149A's Frequency Counter.
Equipment Required
Agilent 3325A/B Synthesizer
Agilent 83650B Synthesizer
Agilent 437B Power Meter
Agilent 8487A/D Power Sensor
Agilent 11730A Power Sensor Cable (provided with 53147A/148A/149A)
Agilent 11667C Power Splitter
Agilent 8490D (Opt. 020) 20 dB Attenuator
Agilent 1250-2015 BNC (m) to SMA (f) Adapter
Agilent 11904A 2.92 mm (m) to 2.4 mm (m) Adapter
Agilent 10100C 50 Ω Feedthrough Terminator
Agilent 10503 Series Coaxial Cable (BNC m to m)
2 mm (m) to 2 mm (f) Cable (2)

Test 1a: 10 Hz to 20 MHz Frequency Sensitivity

• To ensure that the test results are valid, the instrument 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 53147A, 53148A, and 53149A.
If the Agilent 3325A/B Synthesizer or the Agilent 83650B Synthesizer
•
reference output is not adequate to drive the 53147A/48A/49A, connect
the cable from the Synthesizer to the Reference 10 MHz connector on
the back of the 53147A/48A/49A, and set the 53147A/48A/49A to use
the internal oscillator.
