XP8103 9
NER-649S (PCM Systems)
• This is a high performance PCM-FM single conversion receiver
with 10 KHz super narrow band ABC&W circuitry.
• The latest “S” type Central Processing Unit (CPU) is used in the
PCM receiver. The new NER-649S offers the highest resolution
available in any receiver.
• A narrow band ceramic filter for high signal selectivity also
assists in rejecting cross modulation from other common radio
frequencies (e.g., R/C transmitters, local paging systems). It has
the highest degree of resistance to electro-mechanical “noise” to
improve signal reception.
• This receiver features Direct Servo Control (DSC) permits
control of surfaces without radio frequency output.
• The receiver has low current consumption.
• 3-point gold plated connectors allow increased conductivity.
