STANFORD RESEARCH SYSTEMS SR620 Time Interval / Frequency Counter

The Stanford Research SR620 Time Interval Counter performs virtually all of the time and frequency measurements required in a laboratory or ATE environment. The instrument's single-shot timing resolution and low jitter make it the counter of choice for almost any application. The SR620 measures time interval, frequency, pulse-width, rise and fall time, period, phase and events. Time intervals are measured with 25 ps rms resolution, making the SR620 one of the highest resolution counters available. Frequency is measured from 0.001 Hz to 1.3 GHz, and a choice of gates ranging from 1 period to 500 seconds is provided. The SR620 delivers up to 11 digits of frequency resolution in one second, making it suitable for measurement applications ranging from short-term phase locked loop jitter, to the long-term drift of atomic clocks. All measurement modes are supported by a wide variety of flexible arming and triggering options. Specifications. Timebase; Frequency: 10.000 MHz. Stability 0 to 50 °C: 1 ppm, (<2 × 10^-9 Option 01). Settability: 0.01 ppm, (0.001 ppm Option 01). Time Interval, Width, Rise and Fall Times; Range: -1000 to +1000 s in +/-TIME mode; -1 ns to +1000 s in all other modes. Trigger rate: 0 to 100 MHz. Display: LSD 4 ps single sample, 1 ps with averaging. Frequency; Range: 0.001 Hz to 300 MHz via comparator inputs. 40 MHz to 1.3 GHz via internal UHF prescalers. RATIO A/B range: 10^-9 to 10^3 . Period; Range: 0 to 1000 s, RATIO A/B range: 10^-9 to 10^3. Phase: Definition: Phase = 360 × (Tb - Ta) / Period A. Range: -180 to +180 degrees, 0 to 100 MHz. Counts; Range: 10^12, RATIO A/B range: 10^-9 to 10^3. Count: Rate 0 to 300 MHz.

*This is a Web introductory price for one calibration of the STANFORD RESEARCH SYSTEMS SR620. 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.

Crest Factor
Crest factor or peak-to-average ratio (PAR) is a measurement of a waveform, calculated from the peak amplitude of the waveform divided by the RMS value of the waveform

Linearity
Linearity is the relative difference between the displayed power ratio, Dx/D0, and the actual (true) power ratio Px/P0 caused by changing the displayed power level from the reference level, D0, to an arbitrary displayed level, Dx.

Phase Noise
Phase noise is the frequency domain representation of rapid, short-term, random fluctuations in the phase of a waveform, caused by time domain instabilities. Phase noise (L(f)) is typically expressed in units of dBc/Hz, representing the noise power relative to the carrier contained in a 1 Hz bandwidth centered at a certain offsets from the carrier.

Sensitivity
Sensitivity is the minimum magnitude of input signal required to produce a specified output signal having a specified signal-to-noise ratio, or other specified criteria.
