"Off"
Level attenuation is affected via the attenuator stages in the RF sec-
tion; only the remaining part is attenuated in the baseband. The sig-
nal is issued at the RF output with the defined level values.
"On"
Level attenuation is affected in the baseband only.
Note:
This setting is mandatory in the following cases:
●
When only the baseband signal is issued at the I/Q outputs
It is thus ensured that, with power ramping active, this signal is
output with the defined level values.
●
For two-path instruments, when one baseband signal is applied to
two RF paths.
