3 Spectrum Analyzer Mode
3.10 TOI Measurement
Annotation In the Meas Bar, if the Standard path is chosen:
µW Path: Standard
If Low Noise Path is enabled but the LNP switch is not thrown:
µW Path: LNP,Off
If the Low Noise Path is enabled and the LNP switch is thrown:
µW Path: LNP,On
If the preselector is bypassed:
µW Path: Bypass
If Full Bypass Enable is selected but the LNP switch is not thrown:
µW Path: FByp,Off
If Full Bypass Enable is selected and the LNP switch is thrown:
µW Path: FByp,On
µW Path Control Auto
In VMA, WLAN, 5G NR, CQM Modes, an Auto/Man switch is added to µW Path
Control:
This allows the function to automatically switch based on certain Auto Rules as
shown below:
VMA Mode
Measurement µW Path Control Auto behavior
Digital Demod Use Standard Path unless tuned frequency > 3.6GHz and IFBW > 15MHz, in
which case choose Preselector Bypass
Monitor Spectrum Always Presel Bypass
IQ Waveform Use Standard Path unless tuned frequency > 3.6GHz and IFBW >15 MHz, in
which case choose Preselector Bypass
Custom OFDM Use Standard Path unless tuned frequency > 3.6GHz and IFBW > 15MHz, in
which case choose Preselector Bypass
Channel Power Always Presel Bypass
Occupied BW Always Presel Bypass
CCDF Use Standard Path unless tuned frequency > 3.6GHz and IFBW > 15MHz, in
which case choose Preselector Bypass
