Version E.04.00 (April 2016)
- Added support for options
AT2 and SS4.
- Added Pulse Fine
- 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 problem.
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
and its resolution. Note that this
functionality does not apply to adjustments.
The procedure for the Single Sideband Phase Noise test
was updated to a more standardized procedure applicable
across all signal source product lines. An alternative
downconverter method is also provided in addition to the
standard method that can be used when the frequency
range of the reference source is less than that of the
unit under test. Note, however, that the three source
comparison method (useful when the measurand is close to
specification) may not be used in conjuction with the
- Changes to
supported ETE: (electronic test equipment)
the 33611A, 33612A, 33621A, and 33622A as alternatives
for the Function Generator for all applicable tests.
- Added the N9030B as an alternative Spectrum Analyzer
for all applicable tests.
- Added the 34470A as an
alternative Digital Multimeter for all applicable
performance verification tests. The 34470A is not
supported for adjustments.
- Added the U8485A,
U8487A, and U8488A as alternative power sensors for all
applicable performance verification tests. These sensors
are not supportedfor adjustments. (Note that these
sensors require the N1914A Option 201 power meter for
- Added the E8663D as an alternative
reference source for the Single SidebandPhase Noise
- The DSAZ334A oscilloscope is now the
recommended model for the high performance oscilloscope.
- Fixed a timeout issue with
Sub-Harmonic Spurious for units without an attenuator.
- Updated uncertainty calculations to include multimeter
