The device also includes remote control and monitoring capabilities, enabling seamless integration into complex systems.

This timebase is housed in a rugged, anodized aluminum enclosure designed to withstand harsh environments and provide excellent temperature stability. The SR625 is also equipped with internal power supply options, including a universal AC adapter and backup battery, ensuring uninterrupted operation even during power outages.

In summary, the Stanford Research Systems SR625 Rubidium Timebase is an essential tool for applications requiring extreme precision and stability in timing, such as telecommunications, satellite communications, and scientific research. Its robust design, versatile frequency output, and user-friendly interface make it a reliable and indispensable addition to any precision timing system.

1. High Stability: The SR625 Rubidium Timebase offers excellent frequency stability and accuracy, making it ideal for applications requiring precise timekeeping.

2. Long-term Stability: Rubidium atoms have a very long half-life, ensuring the timebase maintains its accuracy for years without needing adjustment.

3. Low Drift: Compared to other atomic clocks, the SR625 has a much lower drift rate, which means it keeps time more consistently over time.

4. Reliability: Rubidium timebases are known for their robustness and reliability, making them suitable for use in harsh environments.

5. Low Power Consumption: The SR625 Rubidium Timebase uses minimal power, making it energy-efficient.

1. Cost: Rubidium timebases, including the SR625, are more expensive than other types of atomic clocks due to the materials and technology involved in their construction.

2. Size: The SR625 is a larger device compared to other atomic clocks, which might be a disadvantage if space is a limiting factor.

3. Complexity: The SR625 can be more complex to set up and maintain than other types of atomic clocks, requiring specialized knowledge and equipment.

4. Limited Frequency Range: While the SR625 offers excellent accuracy and stability, it may not be suitable for applications requiring a wide frequency range.

The SR625 Rubidium Timebase (Stanford SR620 Research) is a high-quality, reliable, and accurate timekeeping solution, making it an excellent choice for applications where precision and long-term stability are critical. Although it is more expensive and complex than other atomic clocks, its benefits in terms of stability, reliability, and low power consumption can justify the investment. If space and frequency range are not major concerns, the SR625 is a recommended choice.

Details:

Convenient cursors allow you to read the value of any data point in the histogram or strip chart. The instrument's single shot timing resolution and low jotter make it the counter of choice for almost any application. This listing is for a Stanford Research Systems model SR620 time interval counter plus SR625 rubidium timebase and 2ghz preschooler.

Built in DBMS and analog outputs two rear panel Dem inputs make measurements of dc voltage s with. The SR620 delivers up to 11 digits of frequency resolution in a 1 second measurement. A rear panel input let's you connect any external 5 MHz or 10 MHz source as a timebase.

Auto scale and zoom features make it simple to display all, or any portion, of the graphs. 3 GHz, and a choice of gates ranging from 1 period to 500 seconds are provided.

Unit passes self test and all performance checks as detailed in the manual starting on page 61. It's suitable for measurement applications ranging from short term phase locked loop jotter, to long term drift of atomic clocks. Measurements the SR620 measures time interval, frequency, pulse width , rise and fall time, period, phase and events. Frequency is measured from 0.

The ref output can be used as a source of start or stop pulses for any of the SR620's measurement modes. Glib, rs 232 and display out are all fully functional from Sr's's data sheet 25 PS single shot time resolution 1. Time intervals are measured with 25 PS RMS resolution, making the SR620 one of the highest resolution counters available. 001 Hz to 1.

Graphical data is available in three formats a histogram showing the distribution of values within a set of measurements, a strip chart of mean values from successive measurements, or a strip chart of jotter standard deviation or Allan variance values from successive measurements. 3 accuracy CDC range. Histograms strip charts unlike conventional counters that only have numeric displays, the SR620 frequency counter provides live, graphical displays of measurement results. Two ADC outputs continuously provide voltage s proportional to the mean and the jotter of the measurement sample.

The SR620 will automatically calculate the mean, standard deviation or Allan variance, minimum and maximum for each set of measurements. Sr's offers a choice of a standard timebase with an aging coefficient of year, or an optional oversized oscillator timebase with only day aging, and about an order of magnitude better short term stability than the standard timebase.

10 MHz reference the choice of timebase affects both the resolution and accuracy of measurements made with the SR620. These values may be read via the interfaces or displayed directly on the front panel. Up to 250 strip chart points, or histogram bins, can be displayed.

Both histograms and strip charts can be displayed on any oscilloscope with an x axis input see pictures, or can be plotted on an hp GL compatible plotter or dot matrix printer. For instance, the length of a cable connected between ref and the b input can be precisely determined by measuring the time delay between ref and b. Reference output a precision 50 duty cycle square wave 1 khz is available at the front panel ref output. Complete statistical calculations the SR620 can make measurements on a single shot basis, or calculate the statistics of a set of measurements.

Sample sizes from one to one million can be selected.
