Information
The SPECTRACOM MODEL 8164 WWVB RECEIVER DISCIPLINED
OSCILLATOR* is a frequency standard with accuracy directly
traceable to the National Bureau of Standards. The
SPECTRACOM MODEL 8206 ferrite loop antenna is used to
receive to 60 kHz carrier of WWVB.
The Model 8164 is continuously monitored against WWVB and
kept on frequency by a microprocessor. The oscillator
outputs can be used as a precise external input for
transmitters, receivers, counters, synthesizers, and other
electronic equipment. Figure 1-1 shows the Model 8164
Disciplined Oscillator and the Model 8206 Antenna.
1.1 FEATURES
The Model 8164 WWVB Receiver-Disciplined Oscillator offers
the following features:
BUILT-IN PHASE COMPARATOR - may be used to compare the phase
of the internal ovenized oscillator or local input with the
received WWVB signal. Results are recorded on the strip
chart recorder.
TRACEABILITY - verification to the National Bureau of
Standards is done by noting the hourly WWVB phase shift
identification. The hourly offsets appear as "tick” marks on
the strip chart recording.
ALARM STATUS - operational status is communicated by alarm
lamps and RS-422 alarm outputs.
SELECTABLE FRONT PANEL OUTPUTS - 0.1, 1.0, 5.0 or 10 MHz TTL
compatible signals of the phase locked and standard
oscillator outputs.
FREQUENCY OFFSETS - with the addition of a frequency offset
option, the internal 10 MHz standard oscillator is offset a
precise amount. The offset frequency used as a reference to
a television or paging transmitter reduces or eliminates
co-channel interference.
DISTRIBUTION OUTPUTS - with the addition of Option 03,
Built-In Distribution Amplifier, up to 25 remote stations
may use the standard outputs as a common time base.
