Spectrum Analyzer Performance Verification 3-6 Spurious Response (Second Harmonic Distortion)
MS20xxC MM PN: 10580-00307 Rev. D 3-11
3-6 Spurious Response (Second Harmonic Distortion)
The following test is used to verify the input related spurious response of the spectrum analyzer in
VNA Master models MS2036C, MS2037C and MS2038C.
Equipment Required
• 10 MHz Frequency Reference Standard, Symmetricom Model Rubisource T&M
• Synthesized Signal Generator, Anritsu Model MG3692X
• K(m) to N(f) Adapter, Anritsu Model 34RKNF50
• N(m) to N(m) RF Coaxial Cable, Anritsu Model 15NN50-1.0B
• BNC(m) to BNC(m) RF Coaxial Cable, Anritsu part number 2000-1627-R
• 50 MHz Low Pass Filter, Anritsu Part Number 1030-96
• N(f) to K(m) Adapter, Anritsu 34NFK50 (for MS2038C with Option 11 Only)
Procedure
1. Connect the 10 MHz Reference to the Anritsu MG3692X Synthesized Signal Generator.
2. Turn on the 10 MHz Reference Standard and the Anritsu MG3692X Synthesized Signal Generator.
3. Press the On/Off key to turn on the MS203xC VNA Master.
4. Press the Shift key and then the Mode (9) key. Use the rotary knob to highlight Spectrum Analyzer, and
then press the Enter key to switch to Spectrum Analyzer mode.
5. Press the Shift key, the Preset (1) key, and then the Preset soft key to reset the instrument to the default
starting conditions.
6. Press the Shift key, the Sweep (3) key, press the Sweep Mode soft key and then press the Performance
soft key to set the instrument to Performance Sweep mode.
Note Before continuing, allow a 30-minute warm up for the internal circuitry to stabilize.
