Better calibration improves spectral purity
Agilent oscilloscopes are constantly improving
their measurement accuracy. The latest
innovation is a new, improved calibration routine
that better aligns the sample points of the
analog to digital converter.
The improved calibration results in higher
spurious free dynamic range (SFDR) and
effective number of bits (ENOB). For instance,
the SFDR is improved by as much as 15 dBC
depending on the carrier frequency. The
higher SFDR is ideal for making RF and optical
measurements where spectral purity is of the
utmost importance. Improved SFDR and ENOB
also means better jitter performance.
Ultimately this means the 90000 X-Series now
features the highest SFDR and ENOB of any
oscilloscope on the market
.
Low real-time oscilloscope jitter measurement floor,
just got lower (now 100 fs)
Oscilloscope bandwidth allows signal rise times to be
more accurately depicted. The oscilloscope noise floor
directly impacts the y-axis voltage placement of each signal
data point. The Infiniium 90000 X-Series scopes combine
superiority in these characteristics with extremely low
sample clock jitter (< 100 femptoseconds). This ensures the
lowest possible contribution to jitter measurements from
the scope itself so you’re using your jitter budget on your
design.
In addition to its low jitter measurement floor, the 90000
X-Series has the industry’s deepest memory with up
to 2 Gpts, allowing you to resolve low frequency jitter
components in a single measurement.
The 90000 X-Series now features an even more advanced
calibration system known as sine wave cal. This sine wave
calibration further lowers spurs caused by ADC interleaving
errors and enables lower jitter and higher spurious free
dynamic range. Sine wave calibration simply builds on its
industry leading accuracy.
Jitter measurement floor of less than 100 fs
Improved calibration improves the spurious free dynamic rang by up to
15 dBc
