Output Power Control
Output Power Control
Output Power Control, available from the Soft Front Panel,
automatically sets the ALC power level and output attenuation
(Option 1E1) when given a desired output power.
The current power level can be adjusted by highlighting one or more
digits with a mouse and entering a power level directly in the entry box
or by using the adjustment arrow keys.
When the value being displayed turns red, the value is out of range; the
synthesizer may still put out a signal with these settings, but the signal
has no specifications or characteristics associated with it.
The following formulas are used to compute output power, ALC power
level, and attenuator level:
or
or
When using these formulas, the following applies:
if an attenuator exists (Option 1E1) then
if Output Power <= -70 then Attenuator Level = 70
else if Output Power <= -60 then Attenuator Level = 60
else if Output Power <= -50 then Attenuator Level = 50
else if Output Power <= -40 then Attenuator Level = 40
else if Output Power <= -30 then Attenuator Level = 30
else if Output Power <= -20 then Attenuator Level = 20
else if Output Power <= -10 then Attenuator Level = 10
else if Output Power > -10 then Attenuator Level = 0
if Option 1E1 is not present then
Attenuator Level = 0
