R&S AFQ100A
I Path Delay (ns)
Q Path Delay (ns)
Frequency Shifts
The frequency offset is defined in the lower part of the
baseband frequency interval. Hence, a quick way to shift the used frequency band in the RF frequency
section is provided without modifying the RF settings of a vector signal generator.
Note:
Frequency shift plus signal bandwidth must not exceed 100 MHz.
