Fig. 5-7: Spectrum limit settings
The limits at the frequency offsets can be configured and the ACP measurements at
these offsets can be enabled. The limits can be configured as maximum absolute ACP
in dBm and the maximum ACP in dBc relative to carrier power.
Minimum requirements for off-carrier emissions are defined in 3GPP2 C.S0011, sec-
tion 4.5.1, "Conducted Spurious Emissions". The table below lists the requirements rel-
evant for the ACP limits for spreading rate 1.
Category Frequency Range Specified Limit
Spreading Rate 1, Band Class Group 450 and 800 885 kHz to 1.98 MHz
1.98 MHz to 4.00 MHz
≤ -42 dBm
≤ -54 dBm
Spreading Rate 1, Band Class Group 1900 1.25 MHz to 1.98 MHz
1.98 MHz to 4.00 MHz
≤ -42 dBm
≤ -50 dBm
The occupied bandwidth shows the width of the frequency range around the assigned
channel frequency which contains 95% of the total integrated power of the transmitted
spectrum. For Spreading Rate 1 the standard OBW should not exceed 1.48 MHz (see
3GPP2 C.S0010, Occupied Bandwidth).
5.2.6.4 OLTR Limits
The mask limits used for the OLTR measurement represent the minimum standard for
"Time Response of Open Loop Power Control" specified in 3GPP2 C.S0011/C.S0033.
5.2.7 Multi Evaluation Measurement Results
The results of the CDMA2000 multi evaluation measurement are displayed in several
different views. Use the "Multi Evaluation > Assign Views" hotkey to selectively enable/
disable a particular view and the "Display > ..." hotkeys to change its appearance and
contents. The views are described in the following sections.
