 | BW: Opens the Select Bandwidth list. Choose from the following bandwidths: 1.4 MHz 3 MHz 5 MHz 10 MHz 15 MHz (may require Option 543, refer to Technical Data Sheet) 20 MHz (may require Option 543, refer to Technical Data Sheet) Cyclic Prefix: Press 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. U/D Link Config: Use the keypad, the arrow keys, or the rotary knob to set the value between 0 and 6 inclusive. 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. Trigger: Opens the Trigger submenu. Trigger Source No Trig or Ext: Press to choose between No Trig or External (Ext). When Ext is chosen, the instrument uses an external trigger input to determine frame start timing for data acquisition. The internal algorithms will search for a frame sync and use the delta between the external timing reference and internal sync to compute a ‘Timing Error’ measurement. Trigger Polarity Rising or Falling: Select the desired edge of the external trigger source to use for reference. Back: Returns to the Setup menu 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. |
