Basic Elements
These are the basic elements that make up the LSA1000:
➢
Amplifier
—
amplifies and conditions the input signal so that it
can be measured most effectively
➢
Analog-to-Digital Converter (ADC)
—
converts the analog
signal into digital form by translating it into a series of sample
points that are then measured and transformed into digital
codes representing the signal samples. Multiple ADC
architecture ensures absolute amplitude and phase correlation,
maximum ADC performance for multi-channel acquisitions,
large record lengths and excellent time resolution.
➢
Acquisition Memory System
— stores resulting digital data
from ADCs. Standard 100K points per channel simplify
transient capture by producing long waveform records that
capture even when trigger-timing or signal-speed is uncertain.
Combining two channels doubles the acquisition memory
length. There are four memories for temporary storage, and
four more for waveform zooming and processing.
➢
System RAM Memory of 16 Mbytes as standard. 64 Mbyte
optional.
