HFV 8000 Generator
Frequency rate of change (ms)
This value defines how quickly the generator moves through the steps during both the
scanning and the tuning phases, in milliseconds. For example, if you set this value to
5, the generator will make tuning adjustments no more than every 5 ms. (See
Table 4-
7 , command 11 , frequency rate of change .)
Tuning goal
When the tuning parameter measurement is below the tuning goal value, the generator
does not adjust the output frequency.
Note: This option of generator does not have the continuous tuning in load power
regulation enabled. For power regulation mode, the generator will tune until a
minimum tuning parameter is found. It then operates at that output frequency
until the RF enable command is turned off, then back on (through the
Generator User port on the HFV unit).
(See Table 4-7 , command 14 , tuning goal .)
Tuning gain
This parameter affects the size of the tuning steps; the larger the number, the greater
the size of the tuning steps.
Note: When setting the tuning gain, be aware that if the gain is set too low, the tuning
function may react to noise in the signal and fail to correct the real direction of
change.
(See Table 4-7 , command 15 , tuning gain .)
Tuning delta limit (Hz)
The tuning delta limit sets the maximum amount of frequency change for each step
during tuning.
Note: When setting the tuning delta limit, be aware that if the limit is set too low, the
tuning function may react to noise in the signal and fail to correct the real
direction of change. The lowest recommended tuning delta limit value is 5000.
(See Table 4-7 , command 16 , tuning delta limits .)
Scan delta frequency (Hz)
This parameter sets the maximum amount of frequency change for each step during
scanning. The typical value is 10,000. (See
Table 4-7 , command 19 , scan delta
frequency .)
