Test 4: Power Reference Oscillator Frequency

Test 4: Power Reference Oscillator Frequency
The internal power reference oscillator is used to calibrate the Power
Meter to the power sensor head. This test verifies that the frequency
output of the power reference oscillator is 50.0 MHz ±0.5 MHz.
Equipment Required
Agilent 53150A Microwave Frequency Counter
Agilent 10503 Series Coaxial Cables (BNC m to m)
Agilent 1250-1535 BNC (f) to Type N (m) Adapter

Power Reference Oscillator Frequency Test

• The instrument and the test equipment must be powered on for at least
30 minutes prior to measuring the power reference oscillator output.
This allows the internal temperatures of the equipment to stabilize.
• This procedure specifies the Agilent 53150A for measuring the
frequency output of the 53147A/48A/49A's power reference oscillator.
If the 53147A/48A/49A's Frequency Counter is known to be in calibration
(see "Test 1: Channel 1 Frequency Sensitivity" on page 1-18), you can
use it in place of the 53150A in this procedure.
Connect an Agilent E9635A adapter to the Agilent 53147A/48A/49A's
Power Meter OUTPUT connector as shown in Figure 1-7.
Connect an Agilent 10503 series cable between the Agilent E9635A
adapter on the Agilent 53147A/148A/149A's Power Meter OUTPUT
connector and the CHANNEL 1 input connector on the Agilent
53150A/51A/52A Frequency Counter.
