[High-precision, high-stability, high-purity master clock for audio A/D device]

Use of the high precision, high stability and high purity of the clock signal eliminates the sense of harshness in the high frequency range (orchestra), and many users have testified to the clarity of the sound.

[True holdover function]

A true holdover function is also provided, which is a proof of high performance GPSDO.　Even if the satellite signal is interrupted by torrential rain or snowfall attenuation, or if the satellite signal is removed, the 10MHz output frequency keeps high accuracy without the slightest fluctuation. Of course, when the satellite signal is recovered, it immediately returns to GPSDO mode.　There is no frequency fluctuation at all during the transition to and from holdover mode.

On some conventional GPSDOs when the satellite lock is lost, they have been unable to function as a frequency reference device because the output frequency jumps or breaks but this unit continues to output the exact 10MHz reference frequency with its automatic holdover function even when the satellite signal is lost.

[12-digit frequency display]

High-precision display of the current output frequency to the nearest 100μHz.

It is nice to see 10 to 11 zeros in a row, 10 000 000 000.0.

The LCD panel also displays other information such as satellite reception status, UTC, and satellite lock information.

[10MHz 2 output as standard (Default: Two 10MHz Sine waves)]

・Right BNC connector：10MHz Sine wave or 10MHz Square wave

・Left BNC connector：10MHz Sine wave or 10MHz Square wave or 1pps Square wave

　Default is two 10MHz Sine waves. You will need to specify when you order if you need the square wave.

[Very high sensitivity].

We have heard from several Trimble ThunderBolt owners and users of other GPSDO that this unit has the highest sensitivity (more satellites captured than others).

If the installation environment of the antennas is the same, it means "higher sensitivity = stronger satellite lock = better ability to maintain frequency accuracy".

[Fast satellite capturing]

This unit takes only a few minutes to capture satellites. This is unmatched in speed.

Just a few minutes after power-on, the LCD display will indicate that the unit has captured the satellite.

In addition, this unit outputs all signals shortly after power-on.

[NMEA signal output]

This unit has an NMEA signal output and works as a GPS/NMEA signal receiver.

Some free software can be used to monitor the NMEA signals. (The NMEA capability is Talk only, does not accept Commands.)

By connecting this GPSDO to a Windows PC via RS232 cable, you may monitor the distribution of satellites over the entire sky, each signal level, signal-to-noise ratio, high precision position information, etc.

If your PC does not have an RS232 port, you can also connect via USB port. In that case, use the "RS232-USB converter cable".

The instructions for connecting to a PC and setting up the recommended NMEA software are given in the instruction manual.

*We check the NMEA output capability before the shipment by our Windows 10 PC and attach the data as a performance data of the product.

We can assure that this unit outputs NMEA data but since the operation of software is dependent on the computer used, it does not necessarily mean that we can guarantee that it works on all computers.

[Strict Product Inspection]

This product is delivered to you after rigorous inspection and verification.

The inspection includes NMEA signal analysis to check the distribution of satellites over the entire sky, each signal level, S/N ratio, and so on.

This also confirms the performance of the receiver circuit and the antenna's directivity pattern over the entire sky.

The test data will be included in the delivery.
