Upgraded version ZYT-GPSDO-3 LCD 10MHz 1PPS OCXO GPS Disciplined Oscillator

Description

Due to the skyrocketing price of chips, shipping costs have increased. The cost of this product has continued to increase recently.
This is GPS Disciplined Clock made with SAMSUNG STP 2878 LF
GPSDO Board. Full tested by Agilent 53220A with  Ex-ref from Trimble Thunderbolt GPSDO.
ZYT GPSDO-3 provides one 1PPS Output, one 10MHz sine wave output, and TWO 10MHz LVTTL/CMOS output. It has a
SAMSUNG
GPSDO Module inside.
Power supply: 10V to 24V DC power supply, typical 12V/1A.
Antenna:
Use an amplified GPS antenna that is
5V LNA compatible
.
The October 8, 2020 version is upgraded as follows
1: Added sine wave 10MHz (optional start forced output) Even if the antenna position is not good, sine wave 10MHz can be used. (The default is not to start) You can set the start time by yourself through the serial port command.
(Please inform if you need to set it up)
2: Added LCD backlight shutdown function. Through the serial port, you can set 0-3600 seconds to turn off the LCD backlight. (The default is 600 seconds to turn off the backlight) After turning off, any key can turn on the backlight.
How many seconds it takes to close can be modified on your behalf. Those who can use serial data 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 and at the same time solves the light pollution problem of long-term power-on.
3: Increase the LCD contrast to adjust through the serial port command, 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 GPSDO module instruction set.
5：Better adaptation to Lady Heather
This clock is recommended as a frequency counter reference is very good.
Star search sensitivity is high.
In the case of locking the antenna, the 24-hour average accuracy reaches ± 0.01mHz
Equivalent to 10.000 000 000 01MHz = 0.000001ppm = 0.001ppb
Without connecting the antenna, it can still maintain the level of ± 0.1ppb, maintaining a very high level every day.
The noise is very low without connecting the antenna.
The peak-to-peak energy of a gate per hour in one second is less than 5 * 10-11 measured with Agilent 53220.
Very suitable for frequency meter reference
Each clock we will power on the star lock test for a week to greatly optimize the aging.
Ensure that high accuracy can be maintained without connecting the antenna.
