Lowest intrinsic jitter
The industry standard for lowest oscilloscope jitter was set with
the development of the 86107A precision timebase reference
module. Mainframe jitter is reduced to levels below 200 fs. Low
oscilloscope jitter allows the true jitter performance of devices
to be seen. Oscilloscope jitter can be driven to even lower levels
when using the 86108A precision waveform analyzer. Precision
timebase hardware has been integrated with the waveform
sampling system to reduce residual jitter to less than 100 fs
(< 60 fs typical!). The highest performance devices can be tested
with pinpoint accuracy.
The 86107A is used in tandem with any of the optical or electrical
sampling modules to reduce mainframe trigger jitter. The 86108A
includes sampling channels, internal clock recovery, and precision
timebase hardware in a single module. The 86108A can derive
a clock from the test signal and internally feed the precision
timebase section. Or an external timing reference can be provided
to the precision timebase. Ultra-low jitter is achieved in either
86108A configuration.
Accurate views of your 40 Gb/s waveforms
When developing 40 Gb/s devices, even a small amount of inher-
ent scope jitter can become significant since 40 Gb/s waveforms
only have a bit period of 25 ps. Scope jitter of 1ps RMS can result
in 6 to 9 ps of peak-to-peak jitter, causing eye closure even if
your signal is jitter-free. The Agilent 86107A reduces the intrinsic
jitter of 86100 family mainframes to the levels necessary to make
quality waveform measurements on 40 Gb/s signals.
Meeting your growing need for more bandwidth
Today’s communication signals have significant frequency
content well beyond an oscilloscope’s 3 dB bandwidth. A high-
bandwidth scope does not alone guarantee an accurate represen-
tation of your waveform. Careful design of the scope’s frequency
response (both amplitude and phase) minimizes distortion such
as overshoot and ringing.
The Agilent 86116C plug-in module includes an integrated optical
receiver designed to provide the optimum in bandwidth, sensitiv-
ity, and waveform fidelity. It extends the bandwidth of the 86100C
Infiniium DCA-J to 80 GHz electrical (93 GHz typical) and 65 GHz
optical in the 1310 and 1550 nm wavelength bands. The 86117A
and 86118A modules provide electrical bandwidths of 50 GHz and
70 GHz respectively. You can build a premier solution for 40 Gb/s
waveform analysis around the 86100C mainframe.
Performing return-to-zero (RZ) waveform measurements
An extensive set of automatic RZ measurements are built-in for
the complete characterization of return-to-zero (RZ) signals at the
push of a button.
