The actual logarithm sweep step ratio is calculated by following equation:
Actual Ratio =
F
n +1
= 1 + Setting Ratio Step Sweep Logarithm
F
n
1000
For Example, if the logarithm sweep step ratio setting is set to 5 and the F
n
is 1000Hz, the
actual ratio is the following:
5___
Actual Ratio =1 + 1000 = 1.005
The F
n+1
, F
n+2
and F
n+3
are the following:
F
n +1
= Actual Ratio × F
n
= 1.005 ×1000Hz = 1005Hz
F
n + 2
= Actual Ratio × F
n +1
= 1.005 ×1005Hz = 1010.025Hz
F
n +3
= Actual Ratio × F
n + 2
= 1.005 ×1010.025Hz = 1015.075125Hz
Note : The maximum value of the logarithm sweep step ratio setting is 10.0 and the minimum
value of the logarithm sweep step ratio setting is 0.0001.
Linear Sweep Time Setting
Logarithm Sweep Time Setting
The sweep time sets the delay time between two frequencies step. It is set from 1 to 1000. The
higher value will put longer delay of two frequencies step.
c. After finishing the linear or logarithm sweep setting, the
, key or can be
used to select sine, square, triangle, ramp up or ramp down (P 1014 / 1016) output
waveform.
