COUPLING
FSP/HP
The COUPLING FSP/HP softkey controls the default coupling ratios for:
• span and resolution bandwidth (Span/RBW) and
• resolution bandwidth and video bandwidth (RBW/VBW)
for the HP emulation mode.
In case of FSP the standard parameter coupling of the instrument is used. As a
result in most cases a shorter sweeptime is used than in case of HP.
The softkey is only available in HP emulation mode.
Remote command: SYST:HPC FSP
