3.2.4 Frequency Sweep Time
The default time from starting to stop frequency is 1s, and time range can set to 1ms~500s. Rotate
multifunction knob, tapType
→ Time tab to pop-out visual numeric keyboard to enter values and select
unit.
3.2.5 Select trigger source
The waveform generator will output a frequency sweep when receive a trigger signal and wait
next trigger source. The trigger source of frequency sweep can be internal, external (external
rising/falling edge) or manual. Rotate multifunction knob or tap ModSrc to step through Internal,
External, ExREdge, ExFEdge, and Maunal.
1) The waveform generator will output a succession frequency sweep when in internal trigger
source. The rate controlled by frequency sweep time.
2) The waveform generator will trigger by the external digital modulation terminal (FSK Trig
connector) on the back panel when in external source. The waveform generator will start
frequency sweep upon receiving a TTL pulse with designated polarity.
Note: In external triggrt source, trigger output will be hidden in parameter list. Because the
