Measurement On/Off: Starts the EMF Measurement and removes access to all other menu buttons. The measurement turns On only if the Center Frequency is set within the valid range and the Anritsu Isotropic Antenna is connected.

Note that the Measurement Time and other related parameters must be set before starting the measurement. This button is useful for stopping or restarting measurements when settings need to be changed. When the measurement is in progress, access to other menus and key presses are blocked.

Measurement Time: Sets the duration of each EMF measurement from one minute up to 30 minutes. The default is 6 min. The instrument captures over-the-air data for the X axis when a valid sync signal is found and a valid Cell ID exists, then moves to the Y and Z axes. There is no axis dwell time parameter. You will get as many isotropic results for the set of three axes as can be obtained within the specified Measurement Time.

When no valid sync signal is found for the current axis, data captured for this axis will be excluded from the measurement results and the instrument moves to the next axis. Refer to Measurement Results (LTE/TD-LTE).

Number of Measurements: Sets the number of EMF measurements to complete from 1 up to 10,000. The EMF test is fully executed when the specified number of measurements have completed.

 

Auto Logging On/Off: Auto Logging is On by default. This must be selected prior to starting the measurements for the results to be logged. The average, max, and min values of each isotropic set of three axes, the isotropic trace data, and the computed total average, max, and min values are saved in a tab delimited text file in internal memory.

The location of this log file is a new folder named with the current time stamp followed by _1, and created in “/Internal Memory/EMF/”. The folder can hold 100 files. Each file holds five measurements. The 101st file and the files created thereafter are stored in a new folder with the same time stamp as the first, followed by _2 (then _3, and so on). Each file has its own time stamp.

Measurement Parameters: Opens the Meas Params Menu (LTE/TD-LTE).

EMF Units: dBm/m2, V/m, and W/m2 are the currently supported units. V/m is the default unit.

Limits: A single number can be entered. The Field Strength (Avg) value is the running average for the current Measurement Time and should stay below this limit (default 6 V/m) for the test to pass. When the Extrapolation Factor is On (refer to Meas Params Menu (LTE/TD-LTE)), the Field Strength (Avg) is extrapolated and the computed value should stay below the limit for the test to pass.

Back: Returns to the previous menu.

 

 

RS Meas Display: Opens the RS Display Menu.

 

 

P-SS Meas Display: Opens the P-SS Display Menu.

 

S-SS Meas Display: Opens the S-SS Display Menu.

 

Extr Factor On/Off: Toggles On/Off the Extrapolation Factor. The extrapolation factor, if turned On, displays the extrapolated field strength number for the selected capture bandwidth.

 

Back: Returns to the LTE/TD-LTE EMF Menu.

 

The displayed Reference Signal parameters below can be changed at the start or at the end of the measurement cycle. All of the parameters are always computed and stored. Once the measurement is complete, any combination of parameters can be viewed (three at a time and in any one of the desired units).

RS Act: Selects the display of Actual Value (current isotropic number).

RS Total Min: Selects the display of Total Min, which is the minimum value for the entire measurement period (Measurement Time × Number of Measurements).

RS Total Max: Selects the display of Total Max, which is the maximum value for the entire measurement period.

RS Avg/Meas: Selects the display of Avg/Meas, which is the running average for the current Measurement Time. This is the default selection.

RS Total Avg: Selects the display of Total Avg, which is the running average for the entire measurement period.

 

Back: Returns to the Meas Params Menu (LTE/TD-LTE).

 

The displayed Primary Synchronization Signal parameters below can be changed at the start or at the end of the measurement cycle. All of the parameters are always computed and stored. Once the measurement is complete, any combination of parameters can be viewed (three at a time and in any one of the desired units).
