HP5370B 精密时间间隔通用计数器

厂家：美国惠普

The Agilent 5370B precison time-interval universal counter offers unsurpassed single-shot resolution and a microprocessor-based design for versatile measurement and complete statistical characterization capabilities. The exceptional single shot resolution is achieved by a unique phase-lockable-phase-startable oscillator, used with a digital vernier interpolation scheme that eliminates the ± count quantization error present in most time-interval counters. Statistical functions include mean, maximum, minimum, and standard deviation within the selected sample size. 

The 5370B allows both positive and negative time interval measurements that are useful for differential phase measurement. Other features include automatic calibration of systematic errors and easy display of triggers. Performance, automation, and ease of use make the 5370B the premier time interval measurement counter for applications in component testing, radar/laser ranging, nuclear systems, calibrations labs, computer peripherals testing, digital communications (jitter analysis), and IC tester verification.

Time Interval：Achieve 20 ps single-shot LSD on time intervals from 0 to 10 s, including negative time (in
which the STOP channel event occurs before the START channel event)

Frequency：Measure up to 100 MHz with 11 digits of resolution in 1 s. Choose gate times down to 1 period：
use 1 period with average mode and access the powerful statistics capabilities

Period：Measure period average from 1 to 100 k samples

Statistics：Reduce external computations, reduce random errors, and improve measurement throughput

Sample size：Select 1, 10, 1 k, 10 k or 100 k samples from the front panel, or 1 to 65,536 samples over HPIB.
For the selected sample size, you can compute：

Mean 
Standard Deviation 
Minimum 
Maximum 
Flexible Arming and Gating：+TI or ±TI with internal or external arming, with or without external hold-off

Full HP-IB Programming and Fast Data Output： 

Up to 800 readings/s in fast binary mode - 125 μs dead time 
10 to 20 readings/s fully formatted - 330 μs dead time 
Time Interval Measurement Characteristics

Range

±TI：-10 to +10 s, including zero 
+TI：10 ns to 10 s 
Resolution：Measurement resolution depends on input ** noise and slew rate.

Accuracy：Time-interval measurement accuracy is influenced by internal systematic uncertainties, triggerlevel
timing error for each trigger edge, and timebase aging in addition to resolution or random uncertainties.
Careful calibration with the HP J06-59992A time interval calibrator and averaging will result in accuracies to
±100 ps.

Frequency and Period Measurement Characteristics

Range

Frequency：0.1 Hz to 100 MHz 
Period：10 ns to 10 s 
Resolution：Measurement resolution depends on input ** noise as well as measurement gate time.

Accuracy：Accuracy is influenced by internal certainties, timebase againg, and noise on the input **.
Periodic timebase calibration minimizes uncertainty due to timebase aging. Internal uncertainties and
noise effects may be reduced by selecting longer gate times, or by averaging results.
