The HP/Agilent 5316B is a low-cost, high-performance universal counter offering frequency, period, time interval, ratio, and totalize measurements. Unique counting circuitry delivers the best of both reciprocal and conventional frequency counting. Programmable functions include all measurement modes, plus trigger level and trigger slope controls. The 5316B is encased in a high-quality metal case that meets strict electromagnetic compatibility standards, making it well-suited to applications such as low-level receiver or high-power transmitter testing. With standard HP-IB interfacing, 5316B is suited for ATE system design or other environments where interference from other equipment is a concern.

Features:

• Exceptional resolution at both low and high frequencies
• Three time-interval modes solve more problems
• Flexible signal conditioning optimized for both frequency and time-interval measurements
• Selectable gate time from 60 ms to 10 s
• 100 MHz A and B input channels
• C Channel increases range to 1000 MHz
• Full frequency range (to 100 MHz) on both input channels
• Proven reliability and excellent RFI protection
• Below 10 MHz, the counter measures the input signal period, then computes and displays the reciprocal frequency with 7 digits of resolution in one second for signals as low as 0.1 Hz. Above 10 MHz, the counter automatically performs as a conventional counter.
• The HP 5316B offers 100 ns single-shot time-interval resolution. Time-interval averaging boosts performance to 10 ps resolution. A time-interval delay ignores spurious signals that would normally cause the counter to trigger.
• Choose ac or dc coupling, a sensitivity control (variable attenuator), and a switchable low-pass filter. Both channels have trigger level controls with easy setting.
