Section 2 Introduction to Interfaces
The peripheral interfaces of the 4041 series spectrum analyzer are mainly located on the rear panel as shown in
Fig 3-3, and they are divided into power interfaces, test ports and digital interfaces.

3.2.1 Power interface
The power outlet and switch is the power interface of the instrument, and it can be used to supply the spectrum
analyzer directly by using external AC power. For the external power interface, the inner conductor is positive,
and the outer conductor is grounded.
3.2.2 Test ports
1) RF input port: for the input of the measured signals. The 4041 series test signal input port is 50 Ω. 4041D/E
model uses N-type female port, and 4041F/G model uses 2.4 mm male port.
2) Tracking generator output port (option): for the output of the tracking generator signal. The range of the
output signal power is -5 dBm ~ -35 dBm. 4041 series tracking generator output interface uses N-type female
port.
3) 10 MHz input/output port: for connecting 10 MHz signal of the external equipment as a reference signal of
the spectrum analyzer; or for the output of the internal 10 MHz reference signal from the spectrum analyzer
for use by the external equipment.
4) IF output port: in the case of zero span, the third or fourth IF signal output can be provided via software
configuration for use by the external equipment.
5) Trigger input port: the 4041 series can be set to external trigger mode. The external trigger source is
connected to the trigger input port of the spectrum analyzer. The output range of the source must be
-5V~+5V. This can be set by the software to use either rising edge trigger or falling edge trigger.
6) GPS antenna port: for connecting the GPS antenna so as to locate the current position of the spectrum
analyzer.
