TZT GPSCSG V2.1 GPS Disciplined Oscillator GPSDO GPS Corrected Signal Generator 20 Stored Frequencies

TZT GPSCSG V2.1 GPS Disciplined Oscillator GPSDO GPS Corrected Signal Generator 20 Stored Frequencies

Description:
It is developed based on open source design: http://sq1gu.tobis.com.pl/pl/index.php?option=com_content&view=article&id=44:generator -si5351a&catid=12&Itemid=107.

It is a GPS disciplined oscillator with a 10KHz-220MHz frequency standard which boasts dual-channel adjustable frequency.

Its firmware has been fully upgraded and 20 groups of commonly used frequencies can directly selected. Thus, it is a must-have for audio enthusiasts! In short, it is suitable for audiophile audio equipment and high-precision instruments.

It supports Beidou and GPS satellites and dual-channel output. Frequencies can be independently adjusted for each channel. And each channel can save 10 frequencies to call arbitrarily.

Channel A can store 10 frequencies by default:
10.000MHz
8.4672MHz
11.2896MHz
12.288MHz
16.9344MHz
22.5792MHz
24.576MHz
27.000MHz
33.8688MHz
38.880MHz

Channel B can store 10 frequencies by default:
22.5792MHz
24.576MHz
44.100KHz
48.000KHz
88.100KHz
96.000KHz
176.400KHz
192.000KHz
352.800KHz
384.000KHz

Hardware Upgraded to V2.1:
1. Upgrade and optimize its circuit design, optimize wiring, and reduce phase noise.
2. Upgraded to a super capacitor as a backup power supply for GPS ephemeris data.
3. Upgrade to double solid capacitor filtering, long-term 1.5A three-terminal voltage regulation, so that the power supply is more pure.
4. Upgraded to real gold plated SMA RF terminal.

Tips:
The frequency accuracy of GPS discipline does not need to consider the crystal oscillator used by the frequency synthesizer. After testing, it can still correct the error of the frequency to 0.01Hz even with ordinary crystal oscillators.
