Information
                                    The Model 3750 is a variable electronic filter that covers
the frequency range from 0o 02 Hz to 20 kHz, and operates in
any one of four functional modes; high- pass, low-pass,
band-pass or band-reject. The mode of operation is selected
by means of a front panel FUNCTION switch. The pass-band
gain is unity (Odb) or 10 (20db), as selected by a front
panel GAIN switch, with attenuation slopes of 6ยป 12, 18 or
24 db per octave* as selected by 2 front panel SLOPE switches.
The cut-off frequencies of both the high-pass and the
low-pass sections are independently adjustable from 0, 02 Hz
to 20 kHz. Operation in the band-pass or band- reject modes
permits passage or rejection of any band of frequencies
between these limits. In the low-pass and band-reject modes,
the filter is direct coupled, passing all frequencies from
DC to the selected cut-off frequency of the low-pass section.
In the high-pass and band-reject modes, the upper 3 db point
is at approximately 1 MHz for 0 db gain, and approximately
200 kHz for 20 db gain.
An optional battery kit {Part No. BK-37 5), consisting of
four (4) rechargeable nickel-cadmium batteries, plus
associated hardware, may be added at any time.
In addition, an optional rack-mounting kit (Part No.
RK-519), is available for installing the 3750 in a standard
19" rack spacing.
