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.

dBc
dBc (decibels relative to the carrier) is the power ratio of a signal to a carrier signal, expressed in decibels. If the dBc figure is positive, then the relative signal strength is greater than the carrier signal strength. If the dBc figure is negative, then the relative signal strength is less than carrier signal strength.

Load Regulation
Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Settling Time
Settling time of an output device is the time elapsed from the application of an ideal instantaneous step input to the time at which the amplifier output has entered and remained within a specified error band, usually symmetrical about the final value.
