Equipment Required for MS2720T with option 732 or 743
• Anritsu MG3695C Synthesized Signal Source (see equipment list for required options)
• Frequency Reference Symmetricom Rubisource T&M
• Anritsu 34VKF50 50 ohm Adapter
• Anritsu 3670K50-2 K RF
• Coaxial cable, BNC(m) to BNC(m), 50 ohm
• Power Meter, Anritsu Model ML2438A
• (2) Power Sensor, Anritsu Model SC7413
• Power Splitter Anritsu Model K241C

Component Characterization
1. Connect both power sensors to the power meter, and then zero the sensors.
2. Connect the 10 MHz Reference source to the 10 MHz Ref In connector of the MG3692x or MG3695C
Synthesized Signal Generator.
3. Connect the Model 1870A or K241C power splitter to the MG3692x or MG3695C output via the 34NN50A
or 34VKF50 adapter, and connect Sensor B to one of the power splitter output connections (refer to
Figure 2-3).
4. Install the 10 dB Fixed Attenuator to the other power splitter output, and then connect Sensor A to the
end of the Attenuator.
5. Set the frequency of the MG3692x or MG3695C to 50 MHz.
