Time and Frequency Distribution

Spectracom offers a variety of devices to enable the effective use of time sources and frequency references in a variety of systems. Applications include clock, signal and timecode amplifiers, source fault-detection and failover, wireless time distribution. We also offer bus-level timing boards synchronized to GPS and IRIG timecodes for stand-alone PCs and embedded computer systems. They can be used as a timecode generator.

Models

---

	7535-001 Quad/IRIG-B Buffer Amplifier (1 to 4)
	The model 7535-001 is a Quad (4) buffer amplifier (1 input to 4 output). Each input is a differential channel routed to four output connectors where every output signal is buffered individually with a unity gain amplifier. This architecture allows four devices to be connected to a single input channel.

	8140 Frequency Distribution System
	Spectracom's Frequency Distribution System comprises of the Model 8140 Distribution Amplifier and combinations of Model 8140T LineTaps, Model 8140MT MultiTaps, and Model 8140VT VersaTaps.

 

---

	8140VT VersaTap
	The standard VersaTap is a single-frequency telecom clock converter whose output is factory-set to 1.544 MHz (T1) or 2.048 MHz (E1). Specify exact frequency at time of order.

 

---

	8143 Signal Selector/Distribution Amplifier
	The Spectracom Model 8143 Signal Selector/ Distribution Amplifier detects failure of either input signal and provides manual or automatic switchover between two frequency sources. The selected input is distributed via twelve buffered output line drivers.

 

---

	8144 Clock Selector/Distribution Amplifier
	The Spectracom Model 8144 Clock Selector / Distribution Amplifier detects failure of input clock and provides manual or automatic switchover between two clock sources. The selected input is distributed via twelve buffered output line drivers.

 

---

	8145 TimeGuard Monitor/Selector
	The TimeGuard monitors the RS-232, RS-485, IRIG B/E signals and time sync status of two NetClock®s (example: WWVB and GPS for time reference redundancy). In the event of a primary clock failure, the TimeGuard, Model 8145 automatically switches to the backup clock. An operator-controlled manual override is provided to select either clock. Outputs: RS-232, RS-485, IRIG

 

---

	8179T TimeTap
	A TimeTap converts RS-485 to RS-232 Time Code, allowing the NetClock® time code to reach as many as thirty-two RS-232 devices spanning 4,000 feet

 

---

	8185 TimeBurst Wireless Time Link
	The TimeBurst, model 8185, receives time code from NetClock®/2 or NetClock® GPS Master Clock via RS-485, then connects to customer-provided radio console, such as for building security radio. Requires RS-485 wiring such as CW04xxx from NetClock® and to radio console.

 

---

	9388 NTP Ethernet Time Server
	The Ethernet Time Server, model 9388, is an NTP Time Server that offers system-wide split-second timing information to computers over an Ethernet TCP/IP network. The Ethernet Time Server, Model 9388, is synchronized to an RS-485 time code provided by a NetClock GPS master clock.

Epsilon Switch & Amplifier System

SAS Switch & Amplifer Systems offer distribution of signals to many devices in applications where timing and frequency is required. SAS models offer automated or manual switching between two precision time and frequency sources. If a fault is detected on one source, the other source is used as the reference. Two versions are available. A 1 RU unit distributes up to (x8)10 MHz, (x8)1PPS and (x1)Time of Day output. A 2 RU unit distributes (x16)10 Mhz, (x16)1PPS, and (x4)time of day outputs.
