To Output FSK Modulated Waveform
For FSK (Frequency Shift Keying) modulation, the generator “shifts” its output
frequency between two preset frequencies (carrier frequency and hop frequency).
This section introduces how to output FSK modulated waveform from the [CH1]
connector (the carrier is sine with 3kHz frequency and 5Vpp amplitude, the hop
frequency is 500Hz, the FSK rate is 100Hz and the modulating polarity is Pos).
1. To select output channel
Press CH1|CH2 to select CH1. Now the boarder of the channel status bar is
displayed in yellow.
2. To set the carrier waveform shape, frequency and amplitude
1) Carrier Waveform Shape: press Sine to select sine as the carrier waveform.
2) Carrier Frequency: press Freq/Period to highlight “Freq”. At this point, use
the numeric keyboard to input 3. Then, select kHz from the pop-up menu.
3) Carrier Amplitude: press Ampl/HiLevel to highlight “Ampl”, and then use
the numeric keyboard to input 5. Then, select Vpp from the pop-up menu.
3. To select FSK modulation
Press Mod Type FSK to enable FSK function.
When Mod is enabled, Sweep or Burst will be automatically disabled (if
enabled currently).
Int and FSK will be displayed in the bottom of the screen.
4. To set hop frequency
Press Hop Freq, use the numeric keyboard to input 500 and select Hz from the
pop-up menu.
