Example
:SEM:BAND:INT 10 MHz
:SEM:BAND:INT?
Notes 10% . 100% of Channel Span Parameter Value
Bandwidth sub op code, 1 is for BTS, 2 for MS. Default is BTS
Note that Bandwidth sub op code 2 is supported only in non-SA Modes. In SA Mode, Bandwidth sub
op code 1 is used for both BTS and MS
If the ref channel is outside the frequency range, the result spectrum will be invalid
Dependencies Not shown in MSR, LTE-Advanced FDD/TDD and 5G NR Modes
In order to maintain backwards compatible with legacy LTE FDD/TDD Modes, the remote command is
supported in LTE & LTE-A converged application
Couplings Cannot be higher than the channel Span. If lower than 1/10 of channel Span, then the channel Span is
reduced to be 10 times the Integ BW
