Key Sequence:
Setup
BW: Opens the Select Bandwidth list. Choose from the following
bandwidths:
1.4 MHz
3 MHz
5 MHz
10 MHz
15 MHz
20 MHz
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
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.
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 .
