Keysight-Agilent 5316A

The 5316A Universal Counter uses a unique custom circuit called the MRC (Multiple Register Counter) which packs counting and computing power into one unit. Frequency range (channel A) is 0.1Hz to 100MHz. Period range is 10 ns to 105 sec, time interval range is 100 ns to 105 sec. Ratio range is 0.1Hz to 100MHz (both channels) and totalize range is DC to 100MHz. HP-IB provides programmable functions and control. Display is an 8-digit LED for superior resolution. The unit is housed in a rack-and-stack metal case, has built-in HP-IB capabilities and front panel access to Channel A and B trigger levels for easy measurement with a DVM.

Options:
001 - TCXO Time Base
003 - 1 GHz C-Channel Input
004 - High Stability Time Base
