Frequency limits
The
frequency limits
parameter sets the range of frequencies over which the HFV unit
will operate. You can set a start frequency, an upper frequency limit, and a lower
frequency limit. (See
, commands
3
,
4
, and
5
,
minimum frequency
,
maximum
frequency
, and
starting frequency
.)
In center frequency mode, all three frequencies are set to the center frequency. In
automatic tuning mode, the HFV unit starts searching for a tune at the start frequency
and sweeps up until a satisfactory tuning is found or until the upper frequency limit is
reached. If a tune is not found, this pattern is repeated.
Frequency rate of change
The frequency rate of change parameter defines how quickly the generator moves
through the steps during both the scanning and the tuning phase, in milliseconds. For
example, if you set this value to 5, the generator will make tuning adjustments no more
than every 5 ms. (See

S
Scan delta frequency
This parameter sets the maximum amount of frequency change for each step during
scanning. The typical value is 10,000. (See
19
,
scan delta
frequency
.)
Scan Threshold
The scan threshold parameter sets a threshold below which the tuning phase begins. If
the scan threshold is set too high, the generator will begin to tune too early and the
tuning will not be optimal. If the scan threshold is set too low, the threshold may never
be reached and automatic tuning will not take over. (See
20
,
scan
threshold
.)
T
TDS
Total dissolved solids.
Tuning delta limit
This parameter sets the maximum amount of frequency change for each step during
tuning. (See
, command
16
,
tuning delta limits
.)
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.
