Firmware for Real-Time Sampling and Averaging
U1084A-AVG
• Synchronous, dual-channel, real-time sampling and
averaging with a maximum trigger rate of up to 500 kHz
• Averaging from 1 to over 16 million triggers per seg-
ment
• Trigger and clock synchronization modes for improved
accuracy
• Noise Suppressed Accumulation (NSA)
As a signal averager, the U1084A takes full advantage of
the high-speed signal processing performance of the mod-
ule to create real-time averaged signals to reduce random
noise levels in repetitive signals.
Low noise, high dynamic range
The U1084A real-time averaging firmware (U1084A-AVG
option) allows real-time acquisition at up to 4 GS/s down
to 488.28 kS/s with binary sparsing (4 GS/s divided by 2ⁿ).
Averaging signals reduces random noise effects, improving
the signal-to-noise ratio, as well as increasing resolution
and dynamic range. The fast sampling rate is achieved with
a single trigger and acquisition, and does not require the
use of equivalent-time sampling techniques.
Full-speed averaging
In contrast to Averagers that use equivalent-time sampling,
the U1084A maintains maximum averaging speed and
does not require additional triggers that reduce the total
measurement throughput.
