Complex Modulation Functionality
E7495A/B Manual Verification
If you find a failure
• If one or more complex modulation types look correct but others
don’t, reload the latest firmware and repeat the test.
• In order to test against any limits, you must have a spectrum
analyzer that can measure channel power or a device capable of
demodulating and measuring complex signals.
In the event of a performance failure, you must send the instrument in for repair.
Verifying the Power Meter Functionality (Option 600 only)
The Power Meter option uses the same measuring hardware as the
E4418B Power Meter. The capabilities are modified for use with the
Base Station Test market.
