Quick Guide for DG4000

5. 10MHz In/Out

BNC female connector with 50Ω nominal impedance. The function of this
connector is determined by the type of clock used by the generator. DG4000 can
use internal or external clock.
 When internal clock source is used, the connector (used as 10MHz Out) can

output 10MHz clock signal generated by the internal crystal oscillator of the
generator.

 When external clock source is used, the connector (used as 10MHz In)

accepts a 10MHz external clock signal.

 This connector is usually used to synchronize multiple instruments.

6. CH1: Mod/FSK/Trig

BNC female connector with 50Ω nominal impedance. Its function is determined
by the current working mode of CH1.
 Mod:

If AM, FM, PM, PWM or OSK is enabled for CH1 and external modulation
source is used, this connector accepts an external modulation signal.

 FSK:

If ASK, FSK or PSK is enabled for CH1 and external modulation source is
used, this connector accepts an external modulation signal (users can set
the polarity of the signal).

 Trig In：

If CH1 is in sweep or burst mode and external trigger source is used, this
connector accepts an external trigger signal (users can set the polarity of
the signal).

 Trig Out：

If CH1 is in sweep or burst mode and internal or manual trigger source is
used, this connector outputs a trigger signal with specified edge.

7. CH2: Mod/FSK/Trig

BNC female connector with 50Ω nominal impedance. Its function is determined
by the current working mode of CH2.

 Mod:

If AM, FM, PM, PWM or OSK is enabled for CH2 and external modulation
source is used, this connector accepts an external modulation signal.
