HP 70120A Universal Counter

The HP 70120A universal counter was designed with ATE environments in mind. It offers the high speed setup and measurements (60 measurements per second) required in today's manufacturing and test environment. This high production throughput is crucial in keeping you ahead of the competition. High throughput, system reference monitoring, and all the features you expect from a universal counter are all available with SCPI-compatible remote commands. The single-slot HP 70120A provides three channels: 100 MHz, 200 MHz (1/2), and 2.4 GHz (1/64). Each of the inputs may be switched between 1 M ohms or 50 ohms. Sensitivity is 100 mV peak-to-peak, and for larger signals, an internal x 10 attenuator allows measurements up to ±100 V peak. Built-in functions include frequency, period, time interval, rise and fall times, ratios, totalize, pulse width, and voltage minimum and maximum for ac or dc. The 10 MHz reference gives the user the option of locking to a house standard or remotely switching in the internal TCXO. The internal TCXO can be ported externally for use as a system reference. A monitoring scheme continuously samples the reference in use, internal or external, even when the HP 70120A is inactive. If a problem occurs this monitoring scheme can immediately provide an interrupt. In addition to the three main inputs, an external arm input is provided. Rear inputs include trigger in, 10 MHz reference in or out, and a gate input.
