Channel 4 (67.25 MHz Visual Carrier)
Output
Frequency Range:
54 MHz to 864 MHz
Standard CATV Channels 2 - 135, Normal operation
HRC, IRC Channels 1 - 135, Selected via internal jumper
Broadcast Channels 2 - 69, Selected via internal jumper
FCC Offsets:
Automatic, +12.5 kHz or +25.0 kHz channel-dependent
Output Level:
+45 dBmV
Output Impedance:
75 Ohm, 10 dB return loss
Frequency Stability:
±5 kHz
Spurious:
-60 dB @ +45 dBmV out
Broadband Noise:
-77 dBc at greater than ±12 MHz offset at +45 dBmV output,
4 MHz bandwidth
In Channel C/N:
57 dB, 4 MHz bandwidth
In Channel Frequency Response:
Within 2 dB
Output Level Note:
The output level of the MPM860AG is intended to be set at or
very near +45 dBmV. The front panel GAIN control adjusts the
input level into the conversion circuitry and not the final output
attenuation. For best noise and spurious performance please
adjust the output level to +45 dBmV with the actual input that
will be used with the device. If more than 1 to 2 dB of variation
is needed to properly equalize the system, appropriate pads
should be placed at the output of the MPM860AG.
