Agilent E-Series Power Sensor Interface Test
The Agilent E-series power sensors have their sensor calibration tables
stored in EEPROM which enables the frequency and calibration factor
data to be downloaded automatically by the power meter. The frequency
and calibration factor data have checksums which are compared with the
data downloaded by the power meter. For the Agilent E4419B dual
channel power meter, this test should be performed on both channels.
Procedure
1. When there is no power sensor connected to the Channel A input
the message “No Sensor” (“No Sensor ChA” on the
Agilent E4419B) appears on the measurement window.
2. Connect the Agilent E-series power sensor to the power meter’s
Channel A input. The message “Reading Sensor ChA” appears.
When all the data is downloaded this message disappears and a
reading is displayed on the measurement window. If the download
fails, a warning message and error flag are displayed on the front
panel. Also, SCPI error message “-310, System Error” is
generated.
3. For the Agilent E4419B repeat these steps for Channel B.
