Modulator 172138
A modulator commonly varies some aspect (amplitude, phase or frequency) of an RF carrier (f',
in proportion to a much lower frequency video or digital input signal (fm). In general, the
input frequency components of the modulation typically extend from DC to 100 MHz, except
for fast data links.
In order to preserve the information content superimposed on the RF carrier, one must insure
that the output system bandwidth is adequate to pass both upper and lower sidebands (i.e. fo
+ fm) without distortion. In fact, system amplifier and channel distortion often will add
residual AM or PM modulation to an otherwise clean transmitter.
The plug-in supports the following alarms:
IMPORTANT: Although OIDs in arrays probably will not change during the device runtime, this
should not be assumed to be the case; some cards MAY be hot-plugged or else
software modules disconnected, which could change the available OIDs.

Device
Communication Status/health sysUpTime (RFC1213) Raise a critical condition if the device stops
responding to polling for a time period defined
by pollinterval X retries.
Device Restart Status/health sysUpTime (RFC1213) Raise a minor condition based on the value of
sysUpTime read is smaller by at least 60 seconds
compared to last reading. The value increase
by 100 every second.
