  1. Power meter N1914A with serial numbers ranging between MY00000000—MY53040007 require Service Note 07 to be applied for measurement repeatability. Please have this service note applied or verify it was applied before using this power meter. The affected service note is N1914A-07.

  2. Not allowed for the following product configurations:

    The dynamic frequency range of this sensor is insufficient for these models.

Connections and Setup Procedures
  • All test equipment requires a 30 minute warmup period to ensure accurate performance.
  • In the following test setup, cables are designated as solid lines and direct connections are designated as dashed lines.
  1. Connect all test equipment as shown.
  2. Connect GPIB cables to all GPIB-controlled test equipment.
  3. While performing this test, follow all instructions on the controller display.

 

Flexible power sensor channel assignment

This test uses flexible power sensor channel assignment and will identify the channel that a power sensor is connected to using the ability of "smart" sensors such as the N848xA, U848xA, and E930xA series to report their full model and serial number. Legacy 848x series power sensors are unable to provide their model or serial number, but their channel is identified during the sensor calibration process by identifying the channel of the sensor connected to the calibrator.

If the wrong legacy power sensor is connected to the calibrator during this process the error can be resolved by disconnecting and reconnecting the power sensor to the power meter which will force a new calibration.

In Case of Difficulty

If this performance test fails, perform the following steps in order:

  1. Check the equipment setup (see above). If the setup is incorrect, make the necessary corrections and rerun the performance test.

  2. If this test fails with the equipment set up properly, refer to the troubleshooting section of the signal generator's service guide. If you do not have a printed copy of the service guide (Option OBW), one is available either on the CD-ROM that came with your signal generator shipment or on the Keysight Website.

  3. If you cannot correct the problem using the troubleshooting procedures in the Service Guide, obtain service from Keysight Technologies. Refer to Contacting Keysight Technologies.
