Product Description
Characteristics
Control Elements | E1- or T1-generator, settable by DIL-switch or control input |
Accuracy of Frequency Outputs | The accuracy of the generated output signals depends on the master oscillator of the preconnected GPS-satellite controlled clock.
The following options are available: Option Short term stability with GPS-synchronization OCXO MQ ±2·10E-10 OCXO HQ ±5·10E-12 Rubidium ±2·10E-12 |
