IRIG Time Code Receiver & Generator Module
TCR180
-
Meinberg Funkuhren GmbH & Co. KG
The module TCR180 has been designed to receive and to generate IRIG-A/B/G, IEEE 1344, IEEE C37.118 or AFNOR NF S87-500 time codes. It is used in applications like data acquisition, standalone computer time synchronization (for systems without a network connection or higher accuracy requirements) or as an IRIG converter device. The frequency locking of the master oscillator to the time code system enables this module to generate fixed and programmable standard frequencies with high accuracy and stability. Various oscillator options allow the cost efficient implementation of different requirements concerning the accurracy of the outputs. The generator of the IMS-TCR module generates pulses per second and per minute and per hour. Four programmable outputs are also available. The pulses are synchronized to UTC-second.

Broadband antennas, compared to half wave dipoles, reduce test time because the technician did not have to stop the test to adjust the dipole antenna for each frequency. Most compliance standards now require the use of such antennas. The latest version of Mil-Std 461E states the used of broadband double ridge guide horn antenna as the antenna of choice for frequencies above 200 MHz.

Calibration Executive Software
CalEasy Series
-
CalEasy is a full-featured, Calibration Executive software package that supports the verification and calibration of Marvin Test Solutions instruments. The software is intended for use by users that prefer to perform in-house calibration and verification for their Marvin Test Solutions instruments. By calibrating or verifying the instrument in-house, the time and cost associated with returning an instrument to Marvin Test Solutions for calibration service can be eliminated or reduced. CalEasy is also used internally by Marvin Test Solutions production to perform initial calibration and to recalibrate the instrument when received for service. This ensures that user and factory based calibration performance is similar. Depending on the specific instrument, standards instrumentation supported for calibration / verification includes a DMM, and a frequency standards module. Some modules require the use of matrix switch card.

Redundant Frequency and Timing Systems
-
A unique feature of our frequency standards and distribution amplifiers is that the two separate parts of the redundant system are identical and can easily be inter-changed, for maintenance purposes. What we mean by this is that that we don't have a "Master" unit and a "Slave" unit. Whatever unit is powered up first becomes the master unit and the other becomes the slave unit.
