3-8 SSB Phase Noise Test Chapter 3 — Performance Verification
3-16 PN: 10370-10372 Rev. B MG3702xA MM
Procedure Using AeroFlex Equipment
This section contains instructions to perform a SSB phase noise test using the AeroFlex PN9000 phase noise
system. For the following test, refer to the test record table in
Appendix A , “Section 3-8 SSB Phase Noise Test:
AeroFlex Test Equipment” .
The following test can be used to verify that the MG3702xA meets its single sideband phase noise
specifications. For this test, an Anritsu MG3694A or B (with Options 3 and 4) signal generator is required to
act as a local oscillator (LO).
Table 3-3 lists the single side band requirements for the local oscillator.
The CW RF output of the MG3702xA is mixed with the CW RF output from the MG3694B LO, which is offset
by 100 MHz. Single sideband phase noise is measured at offsets of 10 Hz, 100 Hz, 1 kHz, 10 kHz, 100 kHz, and
1 MHz away from the resultant 100 MHz IF.
Test Setup
The PN9000 software must be installed and set up according to the instructions supplied with the phase
noise measurement system before continuing with this procedure.
Connect the equipment, shown in Figure 3-7 on page 3-17 , as follows:
1. Connect a GPIB interface cable from the PN9000 system to the MG3694B (LO) rear panel
IEEE-488 GPIB connector.
2. Connect a GPIB interface cable from the PN9000 system to the MG3702xA (DUT) rear panel
IEEE-488 GPIB connector.
3. Connect the MG3694B (LO) RF Output to the LO INPUT of the PN9000 phase detector module.
4. Connect the MG3702xA (DUT) RF Output to the RF INPUT of the PN9000 phase detector module.
