250 kHz
Low-Pass Filter
2791·01A
The 250 kHz Low-Pass Filter IS designed for use wIth the TEKTRONIX 1450-series Television Demodulator
and the I EKTRONIX 1480 Waveform Monitor. It reduces bandwidth between the 1450's Quadrature 75 r2
Output and the External Horizontal Input of the 1480. To minimize ringing aberrations on pulse-type sig-
nals, the filter employs the Bessel filter characteristic (maximally flat time delay).
When installing the filter, connect the output of the 1450 to the INPUT connector of the filler and connect
the OUTPUT cable of the filter to the
1480
input.
