A1000

The Quartzlock A1000 Frequency Reference is a 1U rack-mounted Rubidium Atomic Clock based instrument. Exceptionally low drift is a unique parameter for the A1000. The hourly and daily stability and drift performance are "best available", typically 8x10-13/day, at the 10MHz, low distortion, sine wave, 50 Ohm output.

Warranty is 3 years.

Very high reliability stems from the physics package and Quartzlock's electronics. Long term production has led to MTBF's of well over 100,000 hours.

The A1000 Frequency Reference has a high reliability inbuilt 110 - 240V ac power supply with low noise characteristics.

The A1000 can accommodate many "standard" options to meet customers’ specific applications. Multiple outputs, alternative output frequencies to the standard 10MHz. Mixed output frequencies and ultra-low noise and highest short term stability options all set the A1000 apart from any other 1U frequency reference @ -123dBc/1Hz for 5MHz and-170dBc/100kHz for 10MHz outputs.

Applications include: Space Ground Control Frequency Referencing, Wired and wireless telecom network synchronisation, HDTV and other AM, FM Satcom (Satellite Communications Equipment) and Broadcast TX applications.
