Fig. 3-3 Interface Description
2.1. Power interface
The power interface of the device is for powering the device through DC output of AC-DC adapter or through
external DC power source. The conductor inside the external power interface is positive and the external conductor
is grounded.
2.2 Test ports
1) RF input port: It is used for inputting the signal to be tested. The indicator of the test signal input port of
S3302 series is 50Ω. The N-type female port is applied for S3302D/E and 2.4mm male port for S3302F/G.
2) 10MHz Input/Output port This port is for connecting 10MHz signal of other devices as the reference signal of
the analyzer. It can also be used for outputting the internal 10MHz reference signal for other devices.
3) IF output port: Under zero span, this port can be used for outputting the third or fourth IF signals for other
devices through software configuration.
4) Trigger input port: The external triggering mode of S3302 series is available. The scope of trigger source
must be -5V~+5V when connecting the external trigger source to the trigger input port of the Spectrum
Analyzer. Rising edge trigger or fall edge trigger can be set by the software.
