The Hewlett Packard HP 5316A Universal Counter with Option 003 is a precision measurement instrument for frequency, time interval, period, phase, and totalize functions across electronic testing and calibration environments. Option 003 delivers 11-digit frequency resolution and 100 ps time interval resolution, supported by advanced triggering capabilities and improved time base stability. The instrument accepts input signals from DC to 100 MHz on Channel A and provides both analog and BCD digital outputs for system integration.
