d)
(Optional) For the second signal generator path, disconnect the 2.4 mm (m)-
to-2.4 mm (m) cable from the power meter. Connect the opposite end of the 2.4 mm
(m)-to-2.4 mm (m) cable connected to the interior chamber rear bulkhead 2A port to
the power meter. Repeat steps 11b-11c.
12. When the
Connect VSA Dialog
box appears, complete the following steps:
a)
Disconnect the power meter from all cables.
b)
Reconnect the opposite end of the 2.4 mm (m)-to-2.4 mm (m) cable connected to the
interior chamber rear bulkhead 1A port to the reference antenna.
c)
In the mmWave OTA Validation Positioner Control Panel, set the
Azimuth
to
90°
and the
Elevation
to
-90°
to rotate the antenna as shown in the following figure.
The calibration laser fixture should face the chamber door and the laser should point
up toward the measurement antenna.
d)
Click
Continue
.
13. When the
MeasAntennaV
dialog box appears, set the
Azimuth
to
0°
in the mmWave
OTA Validation Positioner Control Panel to rotate the antenna as shown in the following
figure, then continue with calibration. This ensures that the correct polarization is
measured.
Once the signal analyzer and signal generator paths are complete, the
Calibration
Complete
window appears with the file locations of the path loss results.
Tip
Leave the
Calibration Path
field in the mmWave OTA Validation
Configurator empty to avoid receiving an error or if you do not want to use a
calibration file.
