Parameter Explanation
Default 100
Range 0 to 255
Unit N/A
Knob Step 10
Direction Key Step 20
3. Demod Time
Set the time for the analyzer to complete a signal demodulation after each
sweep. If Earphone is set to “On”, you will hear the demodulated signal
through the earphone during the demodulation. You can use the numeric keys,
knob or direction keys to modify this parameter. For more details, please refer

Parameter Explanation
Default 100 ms
Range 5 ms to 1 ks
Unit ks, s, ms, us, ns, ps
Knob Step 5 ms to 10 ms, step=0.1ms
10 ms to 100 ms, step = 1 ms
100 ms to 1 s, step = 10 ms
1 s to 10 s, step = 100 ms
10 s to 100 s, step = 1 s
100 s to 1 ks, step = 10 s
Direction Key Step in 1, 2, 5 sequence
4. Signal Gain
Set the signal gain to adjust the signal energy. When the signal amplitude is
small, the better demodulation effect can be obtained by adjusting the gain
value. You can use the numeric keys, knob or direction keys to modify this
parameter. For more details, please refer to "Parameter Setting".
