3-4 Frequency Accuracy Spectrum Analyzer Performance Verification
3-6 PN: 10580-00303 Rev. D Model MS20xxB MM
3-4 Frequency Accuracy
The following test is used to verify the CW frequency accuracy of the spectrum analyzer in the MS2034B and
MS2035B models of VNA Master.
Equipment Required
• Synthesized Signal Generator, Anritsu Model MG3692X series
• K(m) to N(f) Adapter, Anritsu Model 34RKNF50
• 10 MHz Reference Standard
• RF Coaxial Cable, Anritsu Model 15NN50-1.5C
• BNC(m) to BNC(m) Coaxial Cable, Anritsu part number 2000-1627-R
Procedure
1. Connect BNC Coaxial Cable between the 10 MHz Reference Standard output and the 10 MHz Ref In
connector of the Anritsu MG3692X Synthesized Signal Generator.
2. Turn on both the 10 MHz Reference Standard and Synthesized Signal Generator.
3. Set the MG3692X output to 1 GHz CW, with an RF output level of –30 dBm.
4. Install the 34RKNF50 Adapter to the output of the MG3692X Generator and connect the 15NN50-1.5C
RF Coaxial Cable between the Adapter and the RF In connector of the VNA Master.
5. Press the On/Off key to turn on the VNA Master.
6. 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.
