4. Frequency Range
4.1 Test purpose
500MHz Mobile Data Radio Terminal (EUT):
To verify that EUT shall operate within the frequency bands from 501.475MHz to 512.9875MHz and from 526.975MHz to 529.4875MHz .
800MHz Mobile Data Radio Terminal (EUT):
To verify that EUT shall operate within the frequency bands form 812MHz to 813.5MHz and from 857MHz to 858.5MHz.
4.2 Conformance requirement
500MHz Mobile Data Radio Terminal:
Tx band: 526.975 ～ 529.4875 MHz (Tx)
Rx band: 501.475 ～ 512.9875 MHz (Rx)
800MHz Mobile Data Radio Terminal:
Tx band: 812 ～ 813.5 MHz (Tx)
Rx band: 857 ～ 858.5 MHz (Rx)
4.3 Method of measurement
The EUT should be situated in an isolated environment from any radio system without transmitting.
The EUT should be switched-on and set in a transmitting (carrier-on) mode for the test required the highest and lowest frequency of the applicant's assignment.
The spectrum analyzer shall be set in sweep mode and shall be operated under the following conditions:
Frequency range: as required for frequency range to be assessed
Resolution bandwidth: no less than 100KHz
Display bandwidth: equal to the measurement bandwidth
Peak hold: Yes
4.4 Test requirement
The test requirements are given in Annex A, and measurement shall be set up as Annex B. In the test equipment, the spectrum analyzer noise floor shall be at least 6dB below the appropriate limits of 65dB.
