The time it takes by the algorithm to find the best frequency, 

with the lowest R/F figure, depends on the distance between 

the current and the final frequency, as well as the complexity 

of the R/F shape. 
In the worst case it should not exceed 10 seconds, but it may 
take as little as a second or less.
To shorten the tuning time you may have to select manually a 

frequency closer to the expected final frequency (e.g. running 

the autotune a first time with the purpose to get this info for 

the next trial).

[10]PARAM Threshold R/F: moving the front panel knob, 
you can set the threshold of the ratio Rev Power/Forw Power 
which has an effect on the Automatic Frequency Tuning, when 
this is enabled.
If the current R/F value is  below the above “Threshold R/F” 
the autotuning has no effect. 

The actual R/F figure is computed every 200 mseconds. We 

suggest to set a number higher than 10%. With smaller figure, 

and a cavity with low Q factor, the system may not be able to 

reach a fixed frequency.

[11]PARAM Reverse Power Max: moving the front panel 
knob, you can set the limit of the reverse power before the 

alarm. The unit can bear a total reflection condition for a 

certain time, but be careful: in case of heavy standing wave, 
the generator may be overloaded with the sum of both forward 

and reverse power, and parts of the circuit on the final power 

combiner, as well as the coaxial socket may be damaged.

Table of Alarm Codes

The alarms are also coded with a number that is emitted on the 
4 bit outputs provided on CONN #5 (see the relevant schema-
tic at page 12).
The following is the table with the indication of the codes.
