E4416A/E4417A Power Meters Service Guide 41
Agilent E-Series Power Sensor Interface Test
Description
Agilent E- Series power sensors have sensor calibration tables stored in
EEPROM. This enables the power meter to download frequency and
calibration factor data automatically. The frequency and calibration factor
data have checksums which are compared to the data downloaded by the
power meter. For the Agilent E4417A dual channel power meter, this test must
be performed on both channels.
This test verifies that the power meter can successfully download this data
from the sensor.
Equipment
• Power sensor cable: Agilent E9288A.
• Power sensor: Agilent E9321A.
Procedure
1 Connect the E9321A power sensor to the power meter's Channel A input.
The following message appears:
• For the Agilent E4416A: Reading Sensor.
• For the Agilent E4417A: Reading Sensor ChA.
When all data has been 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. The SCPI error
message -310, System Error is also displayed.
