MS20xxC MM PN: 10580-00307 Rev. D 3-19
3-8 Resolution Bandwidth Accuracy
The following test is used to verify the resolution bandwidth accuracy of the spectrum analyzer in VNA Master
models MS2036C, MS2037C and MS2038C.
Equipment Required
• Synthesized Signal Generator, Anritsu Model MS3692X
• K(m) to N(f) Adapter, Anritsu Model 34RKNF50
• 10 MHz Reference Standard, Symmetricom Model Rubisource T&M
• N(m) to N(m) RF Coaxial Cable, Anritsu Model 15NN50-1.0B
• BNC(m) to BNC(m) Coaxial Cable (Quantity 2), Anritsu part number 2000-1627-R
• BNC Tee Adapter, BNC(m) to BNC(f)/BNC(f), Anritsu part number 3-2600-2
• N(f) to K(m) Adapter, Anritsu Model 34NFK50 (for MS2038C with Option 11 Only)
Procedure
1. Connect the BNC Tee Adapter to the output of the 10 MHz Reference Standard.
2. Connect the 10 MHz Reference to the Anritsu MG3692X Synthesized Signal Generator.
3. Connect the 10 MHz Reference to the Ext Ref Input connector of the MS203xC VNA Master.
4. Turn on the 10 MHz Reference Standard and the Anritsu MG3692X Synthesized Signal Generator.
5. Set the MG3692X RF output frequency to 1 GHz CW and level to –30 dBm.
6. Press the On/Off key to turn on the MS203xC VNA Master.
7. 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.
8. Press the Shift key, the Preset (1) key, and then the Preset soft key to reset the instrument to the default
starting conditions.
9. Press the Shift key and 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.
