The newest addition to the Spectrum line of products is the TM-4M Time & Frequency System. Incorporating a TM-4/OEM™ and a rechargeable lead-acid battery, the TM-4M allows for both portable service and the confidence of continued operation during power failures. In addition, the TM-4M Time & Frequency System offers six user-selectable outputs on the front panel, including PPS, 10 MHz and any of the standard outputs mentioned above. It is also optionally rack mountable and is available without the backup battery for those who would like the multiple outputs from the TM-4 without extra cables or adapters. Spectrum will offer a Rubidium version of this product in Q2 of 2007. |

The Intelligent Reference/TM-4™ and TM-4/OEM™ are GPS disciplined time and frequency references that feature near-Rubidium accuracy and holdover characteristics while retaining the economy and low phase-noise of quartz-based products. The TM-4 incorporates very advanced technology, including our Intelligent Holdover™ function, simultaneous Event Time Tag (ETT) and Programmed Output Pulse (POP) capability, FastStart™ technology and an optional wide-range filtered timing pulse (synchronous to PPS), with ultra-low jitter. Other optional features include a GPS-locked wide-range frequency synthesizer, a super low power OCXO, and a low cost, power-conserving TCVCXO. The Intelligent Reference/TM-4™ is Stratum-1 compliant, is highly customizable and is available with or without case. |

The versatile Intelligent Reference/TM-4D™ incorporates our TM-4/OEM™ and takes time and frequency references to a whole new level. Integrating a signal generator with both digital and analog distribution amplifiers, the TM-4D generates and distributes timing signals, time code, and both digital and analog signals all in one product. The TM-4D can also be optionally configured to distribute externally-supplied signals. |

The D/A-1 is a versatile distribution amplifier for both analog and digital signals. Built upon the TM-4D chassis but without an internal signal generator, it will distribute four independent digital signals to as many as 24 outputs and two different analog signals to as many as 16 outputs. The D/A-1 features signal indicators for all six amplifier stages, is DC powered and occupies 1U of rack space. |
