The formats are: STANDARD FDM String: F:49.984 FD:-00.016 REF:15:03:30 PLT:15:03:30.368 TD:+00.368[CR][LF] SHORT FDM String: FD:-00.016 TD:+00.368[CR][LF] AREVA FDM String: [STX] 02049.984[CR][LF] 021-00.016[CR][LF] 022+00.378[CR][LF] 02315 03 30.368[CR][LF] 024068 15 03 30 [CR][LF] [ETX] |
| Analogue Outputs | 2 analogue outputs for longtime-recording via 16pin DMC connector (time deviation and/or frequency deviation), range: -2.5V ... +2.5V, resolution: 16Bit |
| Board Dimensions | 160mm x 100mm, 1,5mm Epoxy |
| Board Type | Eurocard |
| Current Consumption | 0.4 A - 1 A (depending on oscillator type) |
| Electrical Connectors | 96-pin VG-rail DIN 41612 |
| Further Information | A preconnected reference is necessary that provides a serial time string and a PPS (pulse per second). The accuracy of the measurements is derived from these signals.
The module calculates the frequency as well as the time, based on the mains frequency. The time deviation (TD) is the difference of this calculated time (PLT) to the reference time (REF). This time deviation as well as the frequency itself is sent out via serial interface or is being converted to an analogue voltage output provided by a DAC. |
| Input Signal | 10MHz, serial time string, PPS (via backplane)
mains frequency, 70 - 270 V AC, 50Hz or 60Hz |
| Power Supply Maximum Power Range | +5V DC |
| Relative Humidity | Max. 85% |
| WEEE Status of the Product | This product is handled as a B2B category product. In order to secure a WEEE compliant waste disposal it has to be returned to the manufacturer. Any transportation expenses for returning this product (at its end of life) have to be incurred by the end user, whereas Meinberg will bear the costs for the waste disposal itself. |
