BW: Opens the Select Bandwidth list. Choose from the available bandwidths. Cyclic Prefix: Press this key to set the instrument to measure signal with a Normal or Extended Cyclic Prefix, or to allow the instrument to detect the Cyclic Prefix automatically. EVM Max Hold: Turn the EVM Max Hold submenu key On to display both the Maximum EVM value since Reset and the current measured value. This applies to EVM RMS and Peak values. Selecting Off displays only the current measured value. EVM Mode: Press to select either Auto or PBCH Only. Selecting Auto measures PDSCH if data is available, otherwise, it measures PBCH. Selecting PBCH Only forces a PBCH measurement and the constellation measurement will only show QPSK. The instrument will automatically choose PBCH Only mode when the OTA Scanner is used. Sync: Opens the Sync submenu. Sync Type: Press to choose between the Normal (SS) or RS (Reference Signal) Sync Type. Only choose RS when there is no sync signal present in the transmitter under test. If RS is chosen and a sync signal is present, no modulation measurements will be available. Cell ID: Identifying information sent by the transmitter in the sync signal. If Normal (SS) is selected as the Sync Type, the Cell ID is extracted automatically from the Sync Signal. The Cell ID must be entered manually when RS Sync Type is selected. For user convenience, the Cell ID is automatically populated from the last measured signal with an SS. Select noSS Antenna: Select the antenna (1 through 3) in a 4x4 MIMO system that does not receive a sync signal. Antenna 0 must receive a sync signal. This selection is applicable only in RS Sync Type. Back: Returns to the Setup menu. Freq Err Avg Cnt: When the count is greater than one, the frequency error value is averaged over past measurements. If the count is one, then no averaging occurs. Ext. Ref. Freq (Only Some Models): Press to set the external reference frequency. The External Reference Frequency list opens. Highlight the desired frequency and press Enter. |
