TX Mask Test
This test verifies the spectral purity of each sector -carrier at a specific frequency , per the
current NEC file assignment . All tests are performed using the external calibrated test set,
controlled by the same command. All measurements are via the appropriate TX OUT connector .
The standard pattern is used (pilot 171 and 43dBm)
The parameters of the TX Mask are as follows:
> -45.0 dBc / 30 kHz@>750 kHz offset
> -60.0 dBc / 30 kHz@ 1.98 MHz offset
The sector -carrier is keyed or dekeyed during the test.
