FG3C-UA 3MHz Sweep/Function Generator |
|
|
| |
|
This function generator provides a substantial
array of output capabilities. It's extremely reliable for heavy
day-to-day usage in electronic trouble shooting, production
manufacturing test or as a bread-boarding signal source.
The FG3C-UA sweep/function generator provides
sine square, triangle waves and TTL or CMOS pulse outputs from 0.3Hz
to 3MHz. A built-in frequency counter with 6 digit display
accurately shows frequency settings. Or use a stand alone frequency
counter for external signals from 5Hz to 150MHz. Control the linear
or logarithmic sweep of any of the selected signal outputs
internally or with user provided external modulating signal. Produce
TTL or CMOS pulses with the duty cycle function. Switchable 20dB
attenuation allows for low signal output.
