1.  [CH1/Sync/Ext Mod/Trig/FSK] 
 
BNC female connector with 50Ω nominal impedance.  
Its function is determined by the current work mode of CH1.  
 
1)  Sync 
When the output of CH1 is enabled, this connector outputs the 
corresponding sync signal. For detailed information about the 
characteristics of the sync signals corresponding to various output signals, 
refer to the introduction in “Sync Set”.  
2)  Ext Mod 
When AM, FM, PM or PWM of CH1 is enabled and external modulation 
source is selected, this connector accepts an external modulation signal and 
the input impedance is 1000Ω. For the detailed introduction, refer to 
“Modulation”.  
3)  FSK 
When ASK, FSK or PSK of CH1 is enabled and external modulation source is 
selected, this connector accepts an external modulation signal whose 
polarity can be set by users and the input impedance is 1000Ω. For the 
detailed introduction, refer to “Modulation”.  
4)  Trig In 
When Sweep or Burst of CH1 is enabled and external trigger source is
