Operation of the remote control keys is almost identical to local operation, with a few important exceptions.
1.
A wireless network connection must first be established between the iPA and the remote control device before any RF
testing can be performed. The most common approach is to configure the iPA as a Hotspot and connect the remote
device to it via WiFi. The factory defaults for this configuration are:
• IP address of iPA: 192.168.0.1
• SSID: Serial number of iPA (i.e. TX**********)
• Password: kaelusap
Note:
The iPA’s networking parameters can only be changed on the local machine, as changing them remotely could
cause you to lose contact with the iPA.
2. A Geo Tag Icon has been added to the screen, as the location services function of the remote control device can be
used to record the location at which each test is performed.

Performing an RTF Measurement
8.3.1 Calibrating the Instrument
Before performing an RTF measurement the instrument must be calibrated using the process described in Section 6.3.
The user will be prompted to perform a calibration when either of the following conditions exists:
• More than 12 hours have elapsed since the instrument was last calibrated
• The RTF sweep settings have been changed, and no valid calibration exists that matches the new settings
Calibrations may also be manually initiated by the user at any time. To trigger a manual calibration, press the CAL button
at the top of the RTF Analysis screen. From this point on the process is the same as that described in Section 6.3.
The results of the calibration process are automatically stored to file. Multiple calibrations for different sweep settings are
permissible. Calibration data is automatically stored and retrieved by the instrument as needed.
8.3.2 Starting an RTF Sweep
To start a new RTF sweep, the following procedure should be used:
1.
Connect the device under test to the Test Port connector of the RTF module, and tighten firmly using a torque wrench.
2. Press the green RF ON/OFF button.
3. The instrument will now perform a low-power return loss sweep. During the sweep the following progress indicator is
displayed on screen:
4. Upon completion of the Return Loss sweep, the instrument checks the peak return loss level against the Return Loss
If the return loss satisfies the Pass/Fail threshold, the instrument will turn on the two high-power transmit carriers and
perform a swept PIM measurement. During the sweep the following progress indicator is displayed on screen:
