It is used to enter such parameter values as the frequency, amplitude and marker, and press
corresponding unit key or the OK key to complete the input.
h)
Reset key
It is used for system resetting, system restart, recovery or restoration. To reset the system, just
press the key and then release it.
2 Test port
Figure 3-8 Test port
The S5105D/E/F microwave analyzer is provided with 5 main test ports on top of the cabinet, namely,
network test port 1, network test port 2, 10MHz reference input/output port, GPS antenna, and spectrum
analyzer mode spectrum input port.
a)
Network test port
The two test ports in the network test mode of the microwave analyzer are the 50Ω and N-type female or
3.5mm/2.4mm male ones, which are marked with Port “1” and “Port 2” respectively, and can be switched
between the RF source and receiver, so as to measure the DUT in both directions.
b) 10MHz reference input/output port
Marked with “10MHz In/Out” and 50Ω-impedance and BNC female adapter, the S5105D/E/F
microwave analyzer can receive the external 10MHz sine wave signal as the phase lock reference
signal, and the input signal shall meet the requirement of 10MHz±100Hz in frequency and 0dBm in
amplitude (limit:
-20dBm - +10dBm); it can also output a 10MHz sine wave signal as the frequency reference signal of
external equipment.
c)
GPS antenna interface
Marked with “GPS” and BNC (female), it is used to connect the GPS antenna, and the built-in GPS is
used to receive the GPS function provided by the module.
d)
Trig In trigger interface
Marked with “Trig In”, it is used to connect the external trigger signal with a 3.5mm female end.
e)
Spectrum input port for the spectrum analyzer mode
Marked with “SA RF In”, it is used to input the signal to be tested in the spectrum analyzer mode, and the
impedance of the test signal input port of the S5105D/E/F microwave analyzer is 50Ω, with N-type
female or 3.5mm male or 2.4mm male port.
WARNING:
The port damage limit level of the S5105D/E/F microwave analyzer is
+27dBm RF power or 16VDC input level. Otherwise, the instrument may
be damaged.

Power and communication ports
The power and communication ports locate at the top left of the cabinet of the S5105D/E/F
microwave analyzer, including the external power port, USB port, network port, SD card port and
headphone port, as shown in Figure 3-9.
