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.

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.
