1) 10MHz reference connector
a)
10MHZ reference output
As shown in Fig. 3-11, the BNC (female) connector can be used for connection between the analyzer and external
reference signal. The 10MHZ external reference signal detected by the port will be used as the reference frequency of
the instrument, instead of the internal reference frequency. The 10MHz reference input port has the following features:
Input frequency: 10MHz±1ppm
Input level: -15dBm to +20dBm
Input impedance: 200Ω
b)
10MHZ reference output
The reference signal with the following features can be provided for the outside through the BNC (female) connector.
Output frequency: 10MHz±1ppm
Signal type: sine wave
Output level: 13dBm±4dB into 50Ω
Output impedance: 50 Ω

2)
General-interface bus connector
As shown in Fig.3-12 this is a 24-pin D-type female connector, meeting the IEEE-488 standards. It is used to
