L.F. output
Frequency range:
30 Hz to 200 kHz with switchable
Typical response curves are
15 kHz low pass filter on f. m.
shown in Figs. 1-2, 1-3,
except on the 1.5 kHz deviation
range.
30 Hz to 50 kHz on a. m.
De-emphasis:
Switchable to 0, 50 or 75 'Sec.
Output level:
Nominally 0 dBm into 600 Q when
On the 1.5 kHz deviation range the
meter reads full-scale, except on
de-emphasis operates on the meter
the 1.5 kHz deviation range when
as well as the demodulated output.
the output is nominally -10 dBm.
