3-7 50 MHz Calibrator Power Level (All Models)
The following procedure is used to measure the Calibrator output power level of the ML248xx and ML249xA
power meters.
Required Equipment
• Agilent 432A Analog Power Meter
• Agilent 34420A Nano Volt / Micro Ohm Meter or equivalent
• Agilent 8478B Power Sensor
Recording Results
Record measurements and calculations from this section in “Pmeas Calculation” on page A-6.
Procedure
1. Connect the Agilent 34420A to the Agilent 432A using the 4-wire cable provided with the Agilent 34420A
See Figure 3-3 for connection details.
shows 4-wire cable provided with the Agilent 34420A, along with two BNC to binding post adapters
needed to connect the four wires to the rear of the 432A power meter.
2. Attach the connector end to the input Agilent 34420A volt meter.
3. Attach the wires with the BNC to binding post adaptors as shown to the rear of the 432A power meter:
