Description
This test procedure uses a power meter to measure the power level of the probe output when the probe tip
is connected through 50 ohms to ground.
Procedure
1. Connect the power sensor to the power meter and allow the power meter to warm up for five minutes.
2. Calibrate and zero the power meter.
3. Enable averaging on the power meter.
4. Connect the power cable on the RF probe to a power source, allow the probe to warm up for at least
three minutes.
5. Connect the probe tip adapter to the tip of the probe. (This effectively grounds the probe tip).
6. Connect the RF probe to the power sensor using a type-N barrel.
7. Read the power meter. If the reading is unstable, visually determine the approximate peak value over
a period of about twenty seconds. Record that value on the test record.
5-8
<17 mV RTI (or 23 dBm at probe output)
