What's New!

Version E.06.00 (April 2017)

    1. Changed the Maximum Leveled Output Power test to Maximum Output Power. This
      reflects a change in measurement methodology that conforms to that used in production.
      As a result, the reported maximum output power will give a better indication of
      the signal generator's performance, although measured values will be limited to
      the maximum power range of the power sensors used. Note that the power meter may
      overrange, but this is anticipated by the new measurement and does not indicate a
    2. Changes to supported ETE (electronic test equipment)
      - Added the U8481A Option 200 and U8485A Option 200 as alternative power sensors for all
      applicable performance verification tests. These sensors are not supported
      for adjustments. (Note that these sensors require the N1914A Option 201 power meter
      for operation.)
      - Added the 33611A, 33612A, 33621A, and 33622A as alternatives for the
      Function Generator for all applicable tests.
      - Added the 34470A as an alternative Digital Multimeter for for all
      applicable tests with the exception of the FM/PM YO Frequency Compensation
      adjustment. This adjustment cannot support the 34470A.
      - Added the N5182A, N5182B, and N5172B as alternative external baseband
      generators for Digital Modulation Power Level Accuracy Relative to CW.
      - Added the E8663D as an alternative reference source for the Single Sideband
      Phase Noise and Residual FM tests.
      - Added the PXA N9030B as an alternative for performance verification tests
      and adjustments that support the N9030A.
      - The following limitations apply:
      - The combination of 8902A and 8903B can be used as an
      alternative for PSA opt 233 in analog modulation tests to
      achieve PSA replacement with PXA for Performance Verification
      tests, however, the 8902A/8903B are now obsolete products.
    3. Updated connection checks for adjustments to allow the customer the
      option to ignore failed connection checks.
    4. Performance Verification tests that use the power meter/power sensor no longer
      depend on fixed channel assignments for a given power sensor but instead detect
      the channel that the power sensor is connected to by relying on the ability of
      "smart" sensors such as the N848x, U848x, E940x series to report their full
      model and serial number. Legacy 848x sensors lacking this capability have their
      channel assignment detected during the sensor calibration process. Please see
      "Known issues" regarding the potential misidentification of legacy sensors
      and its resolution. Note that this functionality does not apply to adjustments.
    5. Defects Fixed:
      - Updated uncertainty calculations to include multimeter Tcal drift.
      - Fixed a FM Scale DAC Offset Adjustment connection check issue.
      - Fixed an issue with Power Level Accuracy with the PSA displaying an
      error message during the test by limiting the resolution bandwidth
      of the PSA to 2 Hz.
