Logarithmic Frequency Sweep
D-14
The Logarithmic Frequency Sweep waveform has the following characteristics:
H Waveform points: 22,000
H Clock frequency: 100 MHz
H Output parameters: Filter 50 MHz
H Equation: range(0,2.2ms)<LF>k0=2.2e–3<LF>k1=5e3<LF>
k2=50e3<LF>k3=ln(k2/k1)<LF>sin(2*pi*k1*k0/k3*(exp(k3*x)–1))
Sweep Period (k0) is 2.2 ms
Start Frequency (k1) is 5 kHz
End Frequency (k2) is 5 kHz
