HP 5371A Frequency and Time Interval Analyzer

The HP 5371A is a general-purpose modulation domain analyzer that captures frequency or time intervals at extremely high speeds. The HP 5371A combines a choice of over 60 arming and triggering configurations with built-in analysis including math, statistics, and limit testing. The HP 5371A uses a continuous measurement time sampling technique to quickly capture and display data. By eliminating reset time, measurement throughput is dramatically increased to more than 10 million measurements per second with a frequency range of up to 500 MHz.

The HP 5371A can help you analyze jitter effects, characterize the transient and steady state responses of a VCO, examine frequency or phase modulation, measure frequency stability, analyze computer peripherals, or measure fast hopping radio signals.

[ Features ]

Calculated Allan Variance specifies frequency stability in the time domain
Broad selection of measurements
Quick and easy-to-use push button analysis
Graphic display and histograms add visual meaning to numbers
Excellent single-shot 10-digit resolution at 150 ps rms
Fast HP-IB throughput with up to 20,000 measurements per second

Calculated Allan Variance

Many applications specify frequency stability by Allan Variance. Allan and Root Allan Variances are calculated and displayed directly, along with traditional statistical parameters. Frequency to 500 MHz is measured with zero dead time, assuring no lost information in the Allan Variance calculation.

Broad selection

Measurements include frequency and period; time interval, +/- time interval, and continuous time interval; positive or negative pulse width; rise or fall time; duty cycle; totalize; phase; and peak amplitude.

Quick and easy

Built-in statistics and analysis mean that you do not have to send data to a computer or write analysis software.

FREQUENCY MEASUREMENT PRECISION

	For Single Measurement:

		Least Significant Digit Displayed:
			+/- (200 ps / Sample Interval) x Frequency
		Resolution:
			+/- (150 ps rms + (1.4 x Trigger Error) / Sample Interval)
			x Frequency

	Accuracy: +/- Resolution +/- (Timebase Aging x Frequency)
				
	For Continuous Frequency Measurements (Mean Estimation):

		rms Resolution:

		(square root of(13.5) x (150 ps rms + 1.4 x Trigger Error) / 
		(No. of Blocks)^1/2 x (No. of Meas. per Block)^3/2 x 
		Sample Interval) x Frequency
			

	Accuracy: +/- Resolution +/- (Timebase Aging x Frequency)
			
	Least Significant Digit Displayed:

		200 ps / sqrt(N)

	Resolution:

		(+/- 150 ps rms +/- Start Trigger Error +/- Stop Trigger Error) /
