{"product_id":"stanford-research-sr620","title":"Stanford Research SR620 Time Interval \/ Frequency Counter","description":"\u003cp\u003e\u003cstrong\u003eStanford Research SR620 Time Interval \/ Frequency Counter, 0.001 Hz to 1.3 GHz\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 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 a 1-second measurement. It's suitable for measurement applications ranging from short-term phase locked loop jitter to long-term drift of atomic clocks. All measurement modes are supported by a wide variety of flexible arming and triggering options.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFeatures:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003c\/li\u003e\n\u003cli\u003e25 ps single-shot time resolution\u003c\/li\u003e\n\u003cli\u003eFrequency Range: 1.3 GHz\u003c\/li\u003e\n\u003cli\u003e11-digit Frequency resolution (1 s)\u003c\/li\u003e\n\u003cli\u003ePhase resolution: 0.001°\u003c\/li\u003e\n\u003cli\u003eStatistical analysis \u0026amp; Allan variance\u003c\/li\u003e\n\u003cli\u003eGraphical output to XY scopes\u003c\/li\u003e\n\u003cli\u003eTimebase (10.000 MHz): 1x10-6\/year; 5x10-10\/day with option 01\u003c\/li\u003e\n\u003cli\u003eGPIB (IEEE-488) and RS-232 interfaces\u003c\/li\u003e\n\u003cli\u003eDisplay: LED\u003c\/li\u003e\n\u003cli\u003e100\/120\/220\/240 VAC (+5 %, -10 %), 50\/60 Hz operation\u003c\/li\u003e\n\u003cli\u003eWeight: 11 lb; Size: 89 mm (3.5 in)H x 356 mm (14.0 in)W x 356 mm (14.0 in)D\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePlease see Datasheet for complete details and specifications.\u003c\/p\u003e","brand":"Stanford Research","offers":[{"title":"S.R.S.
