Pulse input/output connector
As shown in the following figure, this is a 15-pin type D female connector, which can be used to
synchronize the working status of the internal pulse generator. In addition, the external pulse generator
can be used to provide pulse control signal for internal pulse modulator and IF gate.
Its characteristics are as follows:
Pulse width range: 33 ns ~ 60 s
Pulse transition time: 30 ns
Input impedance: 1 K Ohm
DC input:
<
5.5 V
Driving voltage: 0 V (off)+3.3 V (on)

External IF Input Connector
As shown in the following figure, the 5-way SMA interface is used as the external IF input of the
vector network. The two-port model is identified as A, B, R1 and R2, and the four-port model is identified
as A, B, C, D and R. Its characteristics are as follows:
Input impedance: 50Ω
RF input:
<
23 dBm
DC input:
<
5.5 V
0.1 dB compression point: -9 dBm

Automatic test interface connector
As shown in the following figure, this interface is a 36-pin female connector. The network analyzer
and the Material Handler can carry out signaling interaction through this interface, so as to provide users
with a stable and reliable automatic test environment.
