CMU-U99/B99 RF1 level range identical to RF2 option
With the R&S ® CMU-U99/B99 option installed, the input/output level range and the input/output level uncertainty for RF 1 are the same
as for RF 2.
With the R&S ® CMU-U99/B99 option installed, the VSWR of the RF generator and analyzer at RF 1 is as follows:
VSWR RF generator and RF analyzer
10 MHz to 2000 MHz <1.2
2000 MHz to 2200 MHz <1.4
RF1
2200 MHz to 2700 MHz <1.6
10 Measurement bandwidth 21.9 kHz.
