Main output: Outputs sine, square and triangle waveform. BNC, 50 Ω output
impedance.
4
TTL output: Outputs TTL output waveform, BNC terminal.
5
Amplitude control: Sets the sine / square / triangle waveform amplitude.
Turn left (decrease) or right (increase). When pulled out, attenuates the sine / square /
triangle waveform amplitude by -40 dB.
6
DC Offset control: When pulled out, sets the DC offset level for sine / square /
triangle waveform. Turn left (decrease) or right (increase). The range is -5V ~
+5V, in 50 Ω load.
7
Duty cycle control: When it is pulled out, it sets the square or TTL wave duty cycle. For
TTL waveforms, turn left (decrease) or right (increase). For square waveforms (main
output channel) turn left (increase) or right (decrease). The range is 25% ~ 75 %.
