AUDIOLEC'S
LM 306 IS A 3-IN-1 INSTRUMENT |
|
| |
Fo & |Z| measuring instrument
and Sine/Swept Frequency Generator for Sweep
Test of loudspeakers, drivers, horns, Headphones.
LM 306 can also be used as a powered Audio Signal
Generator in testing audio circuits and devices
like Crossover Networks, LMTs.
Continuous sine frequency can
be varied through either key pad or external rotary
control. Output level is varied digitally through
keypad. An external keypad is provided for convenience
of operation. A 20 x 4 backlit LCD display
shows values of output signal frequency, voltage
or current level, Fo, |Z| as per function selected.
A Line Output, max. 150mV, provides signal
for feeding into any external amplifier.
