Heat dissipation grille
In order to ensure good heat dissipation of the instrument, please don’t block this grille.

．
Internal 10MHz output terminal
Establish synchronous or external clock signal with reference frequency of 10 MHz for multiple function/arbitrary
waveform generators. When clock source of the instrument is internal, the output terminal outputs an internal 10MHz clock
signal.

．
External 10MHz input terminal
Establish synchronization of multiple function/arbitrary waveform generators or synchronization with an external 10MHz
clock signal. When clock source of the instrument is external, the input terminal receives an external 10MHz clock signal.

．
Frequency meter interface
Input signal through this interface when using frequency meter (compatible with TTL level).

．
External digital modulation interface
If modulation of ASK, FSK, PSK or OSK signal source is external, input modulation signal is received through the external
digital modulation interface (TTL level). The corresponding output amplitude, frequency and phase are determined by
signal level of external digital modulation interface. If the trigger source of frequency sweep or pulse train is external, the
digital modulation interface will receive a TTL pulse with designated polarity. This pulse can start scanning or output pulse
train with designated recurring number. Input gated signal through the external digital modulation interface if pulse train is
gated; and output trigger signal for frequency sweep or pulse train (if trigger source is external, trigger output will be
hidden in the parameter list as external digital modulation interface cannot be simultaneously used for input and output).
