ZYT GPSDO GPSDO-2 Blue Backlight GPS Disciplined Oscillator 10MHz Low Phase Noise Square Sine Wave

ZYT GPSDO GPSDO-2 Blue Backlight GPS Disciplined Oscillator 10MHz Low Phase Noise Square Sine Wave

Improvements:
1. Added sine wave 10MHz (optional start-up forced output), which is convenient for audiophiles. (Not start by default) You can set start time by yourself through serial port command. (Please let us know if you need to set it up on your behalf)
2. LCD backlight shutdown function. Through the serial port, you can set 0-3600 seconds to turn off the LCD backlight. The backlight turns off in 600 seconds by default. After turning off the backlight, press any key to turn on the backlight. How many seconds it takes to close can be modified on your behalf. Those who can use the serial port can return to the instruction set through the (help?) instruction, follow the instructions in the instruction set and fill in the corresponding numerical settings. Turning off the backlight saves energy while facilitating the light pollution problem of audiophiles with long-term power on
3. LCD contrast can be adjusted by serial port commands and set according to personal preference. Default coarse adjustment 36 (range 32-39), default fine adjustment 18 (range 0-63)
4. Use the instruction HELP to get the module instruction set

ZYT GPSDO Series are Mainly Divided into Three Types:
* GPSDO-1 = module for trimble
* GPSDO-2 = module for SYMMETRICOM
* GPSDO-3 = module for SAMSUNG

GPSDO-2:
- The measured phase noise of this GPSDO is very low, it is a rare good product, very suitable for HIFI enthusiasts
- Phase noise level 1Hz≈-110dBc 10Hz≈-130dBc 1kHz-100kHz≈-160dBc
- When your antenna is locked, the 24-hour average accuracy reaches ±10uHz=0.01mHz, which is equivalent to 10.000 000 000 01MHz =0.000001ppm=0.001ppb
- Not connected to a antenna, it can still maintain the level of ±0.1ppb per day, maintaining a very high level
- After more than three years of testing and improvement, it outperforms other GPSDO that suitable for audio use in the market
- It is recommended to use BNC port square wave or SMA port sine wave output directly without using antenna
- With its strong aging performance, it can fully meet the needs of audio use
- We will energize and lock the satellite for a week for each clock, which greatly optimizes the aging
- Ensure that high accuracy can be maintained even without any antenna

More Details:
- Your antenna must ensure at least 50% of the sky in order to be better locked, and it is not easy to lose the lock after locking
- Power consumption: start 10-24V <1.5A, after stabilization <0.8A
- Configure DB9 serial communication
- Sine wave output port SMA 10MHZ SINE 50Ω ≈1.4VPP ≈7dBm
- 1pps output Second pulse SMA port
- Square wave output port BNC*2 10MHz measuring impedance 50 ohms ≈1.4VPP 1M ohms ≈3.3VPP
- Antenna ANT SMA port 5V can be connected to GPS active antenna. GPSDO provides 5V voltage for antenna
- Screen displays a variety of status information
- Optional LCD backlight: Blue, White
- Time information: Default UTC time, other time can be changed (such as Beijing time)
- Satellite information: visible satellites, lock satellites, track satellites
- PPS deviation output state
- Various conditions such as internal temperature
- Connect to your computer and use the third-party software for Lady Heather to view more information, including GPS satellite trajectories

Package Included:
- 1 x GPSDO

Note:
- The GPSDO does not contain any accessories. If it is needed, please purchase accessories separately.
