STANFORD RESEARCH SYSTEMS CG635 2.05 GHz Synthesized Clock Generator

The SRS CG635 generates extremely stable square wave clocks between 1 µHz and 2.05 GHz. The instrument's high frequency resolution, low jitter, fast transition times, and flexible output levels make it ideal for use in the development and testing of virtually any digital component, system or network. Clean clocks are critical in systems that use high-speed ADCs or DACs. Spurious clock modulation and jitter create artifacts and noise in acquired signals and in reconstructed waveforms. Clean clocks are also important in communications systems and networks. Jitter, wander, or frequency offsets can lead to high bit error rates, or to a total loss of synchronization. The SRS CG635 can provide the clean, stable clocks required for the most critical applications. The SRS CG635 has several clock outputs. The front-panel Q and -Q outputs provide complementary square waves at standard logic levels (ECL, PECL, LVDS or +7 dBm). The square wave amplitude may also be set from 0.2 V to 1.0 V, with an offset between -2 V and +5 V. These outputs operate from DC to 2.05 GHz, have transition times of 80 ps, a source impedance of 50 ohm, and are intended to drive 50 ohm loads. Output levels double when these outputs are unterminated. Specifications. Frequency Range: DC, 1 µHz to 2.05 GHz. Frequency Resolution: 16 digits (f >= 10 kHz), 1 pHz (f < 10 kHz). Timebase (20 °C to 30 °C ambient) Stability: <5 ppm (std. timebase). Phase Noise (at 622.08 MHz) 100 Hz offset: < -90 dBc/Hz. Jitter (rms): <1 ps (1 kHz to 5 MHz bandwidth. Phase setting Range: ±720° (max. step size ±360°). Option 01, PRBS.

*This is a Web introductory price for one calibration of the STANFORD RESEARCH SYSTEMS CG635. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

dBm
dBm (sometimes dBmW) is an abbreviation for the power ratio in decibels (dB) of the measured power referenced to one milliwatt (mW). Zero dBm equals one milliwatt. A 3 dB increase represents roughly doubling the power, a 3 dB decrease, the power is reduced by about one half.

Millimeter-wave
Millimeter-wave is a term that generally refers to frequencies of 26.5 GHz and above. That is where signal wavelengths fall below approximately 10 mm, and thus the terminology changes from centimeters to millimeters.

Power Repeatability
Power Repeatability is the random uncertainty in reproducing the power level after changing and re-setting the power level. The power repeatability is ± half the span (in dB) between the highest and lowest actual power. Note: - The long-term power repeatability can be obtained by taken the power repeatability and power stability into account.

Stability
Stability is the extent to which a specified property, characteristic, or parameter of a substance, device, or apparatus, remains fixed with the passage of time or with varying environmental conditions.
