Description
Frequency Response
Req: 1 V Full Scale: 50 kHz to 6 MHz within 2% of response at 50 kHz.
RI:
Specifications apply for full screen height video input signal, with Variable
Gain off, and Flat filter selected.
Req: X5 Gain: 50 kHz to 6 MHz within 5% of response at 50 kHz.
RI:
Flat filter selected.
Req: Luminance Filter:
≥
30 dB attenuation at 4.00 MHz.
RI:
Response at 15 kHz does not vary between Flat and Luminance filters by
more than 1%.
