A5-8

The Quartzlock A5-8 Distribution Amplifier is a precision distribution amplifier for use with Frequency Standards or other signals where a need for multiple outputs from a single generator is required.
Available in 8 outputs. The A5-8 replaces previous A5 models; the specification has improved
isolation and other parametrics.

Features
• High Isolation between inputs and outputs
• Ultra low phase noise
• Ultra high stability
• Very low harmonic distortion
• Bipolar Junction Amplifiers 24Vdc BBU &/or 90 ... 240Vac operation

Benefits
• Hydrogen Maser compatible performance
• Retains original input signal characteristics
• 8 outputs
• May be supplied with two or three channel inputs
• No cross channel interference between outputs for mission critical applications

Applications
• Frequency Distribution where the highest levels of stability and lowest levels of phase noise are required
• National Standards Laboratories
• Calibration Laboratories
• Research and Development
• Production Test
