1. CH1/CH2 Sync/ExtMod/Trig Connector
BNC connector with 50Ω nominal output impedance and 1KΩ nominal input
impedance.
Its function is determined by the current working mode.
⚫ Sync:When 1Output is enabled, this connector outputs the sync signal
corresponding to the current settings of CH1 (refer to the introduction in
Sync).
⚫ ExtMod:If modulation mode is enabled for CH1, and external modulation
source is used, this connector accepts an external modulation signal.
⚫ Trig:If CH1 is in sweep or burst mode and external trigger source is used, this
connector accepts an external trigger signal (the polarity of the signal can be
set).
2. 10 MHz Reference In/Out (10MHz In/Out)
BNC connector with 50Ω nominal output impedance and 5KΩ nominal input
impedance. The function of this connector is determined by the type of clock used
by the generator. HDG3000B can use internal or external clock (refer to the
introduction in "Clock Source").
⚫ 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 (refer to
the introduction in "Clock Source").
3. Counter (0~3.3V, external signal input)
BNC connector with 500Ω nominal input impedance. It is used to accept an
