3-10 Third Order Intercept (TOI) Spectrum Analyzer Performance Verification
3-30 PN: 10580-00303 Rev. D Model MS20xxB MM
3-10 Third Order Intercept (TOI)
The following test verifies the Third Order Intercept point (also known as TOI or IP3) of the spectrum analyzer
in VNA Master Models MS2034B and MS2035B.
Equipment Required
• Frequency Reference, Symmetricom Model Rubisource T&M
• Synthesized Signal Generator, Anritsu Model MG3692x (Quantity 2)
• Power Splitter, Aeroflex/Weinschel Model 1870A
• Power Meter, Anritsu Model ML2438A
• Power Sensor, Anritsu Model MA2442D
• Fixed Attenuator, Aeroflex/Weinschel Model 44-2 (Quantity 2)
• Fixed Attenuator, Aeroflex/Weinschel Model 44-6 (Quantity 2)
• Fixed Attenuator, Aeroflex/Weinschel Model 44-20 (Quantity 2)
• RF Coaxial Cable, N(m) to N(f), Anritsu Model 15NN50-1.5C (Quantity 2)
• Adapter, Anritsu Model 34NN50A
• Coaxial Cable, BNC(m) to BNC(m), Anritsu Part Number 2000-1627-R (Quantity 3)
• Tee Adapter, BNC(m) to BNC(f)/BNC(f), Anritsu Part Number 3-2600-2 (Quantity 2)
Procedure
1. Connect the equipment as shown in Figure 3-8. The power splitter will be used as an RF combiner (the
normal RF outputs will become inputs, and the normal input will become the RF output). Do not connect
the power sensor at present.
Note Ensure that the 10 MHz external reference is connected to the MS203xB.
