As an example of a UE spectrum emission masks (i.e. CDMA UL as interferer), TS 25.101 [3] indicates that the power of any UE emission shall not exceed the levels specified in Table 66.
Table 66: Spectrum Emission Mask Requirement
Δf in MHz | Minimum requirement | Measurement bandwidth | |
Relative requirement | Absolute requirement | ||
2.5 - 3.5 |  | -71.1 dBm | 30 kHz |
3.5 - 7.5 |  | -55.8 dBm | 1 MHz |
7.5 - 8.5 |  | -55.8 dBm | 1 MHz |
8.5 - 12.5 MHz | -49 dBc | -55.8 dBm | 1 MHz |
Note 1: Df is the separation between the carrier frequency and the centre of the measurement bandwidth. Note 2: The first and last measurement position with a 30 kHz filter is at Df equals to 2.515 MHz and 3.485 MHz. Note 3: The first and last measurement position with a 1 MHz filter is at Df equals to 4 MHz and 12 MHz.

Table 66 provides directly the values in dBc which are also the format for the SEAMCAT input. Therefore the values from Table 66 translate into SEAMCAT as illustrated in Figure 381.
