3 IQ Analyzer (Basic) Mode
3.1 Complex Spectrum Measurement
Measurement µW Path Control Auto behavior
Analysis
Spectral Flatness Always Presel Bypasss
Power vs Time Always Presel Bypass
Monitor Spectrum Always Presel Bypass
IQ Waveform Always Presel Bypass
Channel Power Always Presel Bypass
Occupied BW Always Presel Bypass
CCDF Always Presel Bypass
SEM For 11be 320M, when ‘Enabled Wideband IF for FFT’ is OFF or ‘Sweep Type
Rule’ is Best Dynamic Range, auto µW path is standard
For other cases, auto µW path is presel bypass if presel bypass is enabled, auto
µW path is standard if presel bypass is not enabled
Spurious
Emissions
Always Standard Path
5G NR Mode
Measurement µW Path Control Auto behavior
Modulation
Analysis
Use Standard Path unless tuned frequency > 3.6GHz and IFBW > 15MHz, in
which case choose Full Bypass if conditions warrant(FBP Option is available
and “Allow Full Bypass in Auto” is On ), otherwise choose Preselector Bypass
Monitor Spectrum Always Standard Path
IQ Waveform Use Standard Path unless tuned frequency > 3.6GHz and IFBW > 15MHz, in
which case choose Full Bypass if conditions warrant(FBP Option is available
and “Allow Full Bypass in Auto” is On ), otherwise choose Preselector Bypass
Channel Power Always Standard Path
Occupied BW Always Standard Path
CCDF Use Standard Path unless tuned frequency > 3.6GHz and IFBW > 15MHz, in
which case choose Preselector Bypass
ACP Always Standard Path
SEM Always Standard Path
Spurious
Emissions
Always Standard Path
Transmit On|Off
Power
Use Standard Path unless tuned frequency > 3.6GHz and Info BW > 15MHz, in
which case choose Preselector Bypass
Channel Quality Mode
Measurement µW Path Control Auto behavior
Group Delay Use Standard Path unless tuned frequency > 3.6GHz and IFBW > 15MHz, in
