LBE-1421
Low jitter GPS-locked frequency clock source with 2 outputs with one as selectable PPS output.
1 Hz to 1.4 GHz output
This device outputs high purity signal with frequency locked to GPS.
LBE-1421 is perfect for both - accurate frequency calibration and RF reference use in mixers or multipliers. It has an additional output which can be programmed for different frequency outputs.
Frequency stability of its output is defined by the accuracy of GPS satellite onboard Caesium references and approaches 1x10-12 or 0.000001 ppm.
Output phase noise is shaped by high quality internal TCXO, providing clean clock signal with sub-picosecond RMS jitter.
Multi-loop digital-analog PLL allows output frequency to be set to any value between 1 Hz and 1.4 GHz with infinite resolution. For example, 144800000.025Hz
LBE-1421 can often be pushed to operate beyond its guaranteed frequency range - all the way up to 1.5 GHz.
Output signal is a 3.3V CMOS square wave with 50Ω source impedance. It can be used directly by most instrumentation and RF equipment.
LBE-1421 comes with a magnetic base active GPS antenna.
Output power level (at 10MHz, fundamental power channel): +11dBm
Typical phase noise at 10MHz:
-72 dBc/Hz at 1 Hz
-101 dBc/Hz at 10 Hz
-128 dBc/Hz at 100 Hz
-147 dBc/Hz at 1 kHz
-156 dBc/Hz at 10 kHz
-159 dBc/Hz at 100 kHz
-164 dBc/Hz at 1 MHz
Power draw through 5V USB is 250mA max
Rise/fall time of output signal at 10MHz is 300ps/260ps measured between 10% and 90% levels.
Operation requires presence of GPS signal, however temporary satellite signal loss is handled seamlessly with no frequency or phase jumps. Active or passive antennas are supported. An active antenna with 5 metre cable is provided but can be substituted by other common types. GPS acquisition time after power-up is around 30 seconds. If GPS signal is lost, digital PLL will maintains best estimated output frequency based on historical data. On reacquisition of GPS lock, output is seamlessly brought back in sync with GPS reference. Entry and exit of this frequency hold is glitchless.
Frequency setting is configurable via USB connection from Windows PC.
Satellite signal NMEA data telemetry is available via virtual serial port over USB connection.
GPS clock can be powered via USB-C connector from a PC, USB charger or USB power bank. LBE-1421 comes ready to use and configured for 10MHz output. USB connection to computer is required only for configuration changes. All settings are stored inside the device and maintain values when off. The SMA antenna connector voltage is 3.3V. Most active antennas marked as 3.3V or 5V will work.
Examples of use include:
10.000MHz, 1.000MHz or other frequency reference for lab equipment and instrumentation
reference for transmitter equipment - HAM equipment, propagation beacons, frequency markers, VHF, UHF and microwave converters.
reference for receiving equipment, RTL SDRs (28.8MHz) and band scanners
calibration source for radio receivers
master clock for audio and video equipment, DACs and studio recording gear

Shipping & Returns
Ordering from the EU
We have recently started shipping orders from a partner company in the EU; SkunkRF who are located in France. This will mean that you will pay import VAT at checkout instead of on import, reducing fees and vastly reducing shipping times. For companies in the EU with a valid EU VAT number, please contact support@leobodnar.com in advance so we can set up your account for 0% VAT orders.
Tracked International Mail (Airmail)
Web orders are processed every working day. Orders are shipped with FedEx International Connect, this method is significantly slower than FedEx Express. Please use FedEx Express when orders are urgent.
UPS and FedEx shipping as usual
At the moment, UPS or FedEx courier delivery are the best options to guarantee a reliable delivery of your order.
Import Charges
We are located and are shipping from the UK and the EU. Shipping to any country not in the UK or EU is subject to import duties and taxes, please make sure you are aware of these before ordering.
The vast majority of orders are dispatched within 1 working day, however large orders or items which require manual assembly may take slightly longer. We will usually inform you if this happens.
International Shipping
Orders to destinations outside the United Kingdom are dispatched via tracked Airmail, UPS or FedEx. You can select your shipping option at the checkout page - click the Estimate Shipping button in the shopping cart to view the shipping option costs. Shipping cost depends on the total weight of the goods.
Orders over £100 and heavy items may only be sent via FedEx.
