Symmetricom 87-360-000 XL-DC FTM III AC Line Frequency Measurement Monitor Card

Description: Tested/Guaranteed • Removed from Working XL-DC Unit • Part 87-360-000 • FTM AC Line Frequency Measurement • Time Monitor • Was $1,295 • Used, Very Good Condition Photos show the actual item for sale This was removed from a working XL-DC unit within which it was recognized by the firmware and it offered the ability to set both the large and small LCD displays to show the results of the AC frequency measurement. It is not thought to be compatible with devices other than the XL-DC Description - Frequency and Time Deviation Monitor This plug-in card meets the specific needs of the electrical power industry. It provides a digital display and computer compatible outputs of the following parameters: Frequency Deviation – The instantaneous difference between the locally generated frequency (typically 50 or 60 Hz) and the precision frequency of the host Synchronized Clock. System Frequency – The user’s locally generated frequency. Time Deviation – The accumulated difference in time between a clock locked to the locally generated frequency and the precise time of the Synchronized Clock. System Time – (Hours, minutes and seconds) as defined by a clock running off the user’s locally generated frequency. Local Time – Local corrected UTC time seconds through days. Both the display port and the communication port have user-selectable baud rates, parity and the number of data bits and stop bits. The monitored frequency and time deviation values are available via the front panel display(s), the communication port, and the remote display driver RS-232 port. GENERAL SPECIFICATIONS Measurement input: 95–260 VAC, 40–70 Hz; user-selectable 50 or 60 Hz operation. Signal conditioning: RFI input filter; multistage low-pass filter. Line fused; varistor protected 2500 VAC rms isolation. Transformer coupled. Remote display port: RS-232. Each output term has individual address codes. FREQUENCY DEVIATION Current deviation of the measurement input frequency from the nominal frequency (50 or 60 Hz).Measurement Sample Rate: 1 sample per second Range: ±9.999 Hz Measurement resolution: 30 μHz. Output data resolution: Resolution to 1 mHz TIME DEVIATION Accumulated time drift due to user’s local frequency difference as compared to the host clock. The user can enter an initial time offset. Measurement sample rate: 1 sample per second Range: ±99.999 seconds Measurement resolution: 500 nS Output data resolution: 1 mS Time offset input: ±99.999 seconds maximum. Entry via keypad or communication port. SYSTEM FREQUENCY Current measurement of input reference frequency. Range: 40 - 70 Hz Measurement Resolution: 30 μHz Output Data Resolution: 1 mHz SYSTEM TIME Arithmetic value calculated from local time, plus user-entered offset, plus time deviation.
