Port Switching - Deepace KC908 Manual

e. Frequency Rounding
Since the deviation of the signal's frequency and the limit of detecting
precision, the peak list contains a lot of data with multiple digits of non-zero
tails. It's inconvenient because it's not the common interval of like 25kHz or
200kHz. This function is designed to trim these tails.
In the frequency rounding setting, rounding interval determines the
interval to round the tails. For 25kHz channel, this parameter should be set to
25kHz or 12.5kHz, while for FM frequencies 50kHz or 100kHz. Start frequency
determines where the interval starts. A MW broadcast starts from 531kHz with
a interval of 9kHz would be rounded like 531, 540, 549, etc. For frequencies
above VHF, the start freqeuncy would usually be set to 1MHz or 1GHz. The
start frequency can be set to higher than the lowest frequency in the list.
After enabling this function, those signals within half the rounding interval
higher/lower than the "integral" frequency would be deemed as that "integral"
frequency.
Frequency rounding function's priority is lower than other filters.

(5) Port Switching

In config menu, port switching is used to swtich the port being used. Each
press would switch once between left/right port.
