Power Meter Operation
Calibrating the Power Meter
| Calibrating the Power Meter |
| This section describes how to calibrate the power meter. You should |
| always zero the power meter prior to calibrating it. |
| Calibration sets the gain of the power meter using a 50 MHz 1 mW |
| calibrator as a traceable power reference. The power meter’s POWER REF |
| output or a suitable external reference is used as the signal source for |
| calibration. An essential part of calibrating is setting the correct reference |
| calibration factor for the power sensor you are using. The HP 8480 series |
| power sensors require you to set the reference calibration factor. The |
| HP |
| automatically. During calibration the wait symbol is displayed. Offset, |
| relative and duty cycle settings are ignored during calibration. |
|
|
Note | During calibration the power meter automatically switches the |
| power reference calibrator on (if it is not already on), then after |
| calibration it switches it to the state it was in prior to the |
| calibration. |
