Spectrum Emission Mask Measurement Description

Input Signal Requirements

• For this measurement the test set's receiver uses autoranging to adjust for the level of the signal being
measured; therefore the expected signal level does not need to be specified during measurement setup.
• The frequency of the signal being measured must be in the range of 800 MHz to 1000 MHz, or from 1700
MHz to 1990 MHz.
• The level into the test set's RF IN/OUT connector must be in the range of +5 dBm to +28 dBm, in a 3.84
MHz bandwidth.

Trigger Source

The trigger source defaults to Auto and tries to use protocol triggering if the UE is synchronized to the test set.
Immediate triggering is used if the UE is not synchronized.
If you want to measure the spectrum emissions for a specific timeslot, use the trigger delay parameter.
This measurement can be made over a period of 1 ms to 10 ms by altering the measurement interval
parameter.

Measurement Calibration

This measurement should be calibrated using the Calibrate Measurements function
("CALibration:MEASurements?" on page
last calibration. If this situation exists, the integrity indicator value becomes 19 and a message is displayed
indicating "Uncalibrated Due to Temperature".
