Model 625 Arbitrary Waveform Function Generator |
|
|
 |
|
Medical
The Arbitrary Waveform Generator will simulate the
outputs from biological and medical sensors. With a
digital storage oscilloscope one can capture a
sensed signal and download it for regeneration by
the Model 625A. The various operating modes of the
625A provide many useful stimuli, gating, and timing
signals for recording, monitoring, and testing
functions.
Educational
The Model 625A provides AM, FM, SSB, FSK, and other
signals for instruction and laboratory environments.
The VCO, pulse and word generator, and DTMF modes
are among the many useful functions for the
classroom and teaching lab.

The BNC Model 625A (SG-100A/Telulex)
represents a major breakthrough in price/performance
for signal generation and signal measurements and
analysis. This versatile device allows the engineer
to access a broad range of operating modes such as
arbitrary waveform, pulse, word/data integration,
function, VCO, AM, FM, SSB, FSK, and burst.
The BNC 625A is much more than a
a signal generator: Never before has so much
versatility, capability, and performance been packed
into a single-low cost instrument. Its architecture
is based on the latest advances in DSP and DDS
technology which not only ensures calibrated and
drift free performance, but also gives the engineer
signal measurement and analysis functions such as
voltage/power measurement and DTMF detection.
The BNC 625A delivers clean,
fully synthesized, DC to 21.5 MHz modulated or
unmodulated waveforms with ) 0.01 Hz frequency
resolution and 1mV and 0.1 dBm amplitude resolution.
User friendly features include a large, easy-to read
LCD display which allows the user to see all
modulation parameters simultaneously. A full numeric
keypad and encoder provides direct editing of each
parameter, without confusing sub-menus.
Areas of application include:
medicine, education, communications, photonics,
circuit design, power systems, and consumer
electronics. |
